...Effects of Routing on Current Communication Methods Used by Organizations Communicating to the consumer is the key element in a successful business. Due to a fast paced world there are modernized techniques that all companies need to adapt and implement when it comes to marketing. There is several ways a company can reach out to their clients. A company must dedicate their time to keep their presence known to the public. In order for Johnson and Company to stay competitive and market to their clients and prospects, there are suggestions I have to help make this happen. First, the phones systems need to be updated from an analog system to a Voice Over IP (VOIP) system. One of the main advantages of VOIP is receiving and taking calls away from the office, if you have an internet connection. Another advantage to a digital phone system is clear and crisp sound creating a better experience for the caller. With VOIP you can set up phone conferences allowing you to see and hear the client or vendor. An after-hours machine can be utilized to provide information on the company and its products, website information, and any other details you want your customer to know about. (Zultys n.d.) Another upgrade that would need to take place is the way the customer orders are handled. A POS system is a way to analyze data sales, maintain a sales history, and improve accuracy by integrating bar-codes and having the ability to take credit card transactions. (Point of Sale System n...

... The Johnson Company is a small business that provides networking components and services. They are in need of new methods of communication for reaching out to new customers, standing out from other businesses, meeting existing customer needs, and keeping customers informed of news and updates. The Johnson Company still uses analog phone lines and still takes customer orders by hand. Their only current method of advertising is an ad in the yellow pages. They have reached out to our IT consulting firm to help them update their current business processes and communications Setting up an intranet site is one of the best ways for small businesses to keep all their workers in the loop and communicate new information. The Johnson Company can also use Microsoft SharePoint application and services to set up internal websites designed for specific projects. Providing customers with a website capable of taking online orders while advertising online as well would give the customers ease of access and efficiency. Project managers can also use these specialized websites to share documents and information, and this can help the projects run more smoothly and effectively. Email is one of the most widely used forms of technological business communication. Instant messaging services such as Skype and Go To Meeting are very up and coming and can provide better communications even more than email. Online advertising, forums, blogs, as well as some possible radio ads may also increase clientele...

...A REPORT ON CURRENT BGP PROBLEMS AND SUGGESTED SOLUTIONS CS526- Assignment# 4 Amit Jhamb & Bhavani Prasad University of Missouri- Kansas City BGP Overview The Border Gateway Protocol (BGP) is an exterior gateway protocol (EGP) also known as inter-Autonomous System routing protocol. The primary function of a BGP speaking system is to exchange network reachability information with other BGP systems. This network reachability information includes information on the list of Autonomous Systems (ASs) that reachability information traverses. This information is sufficient to construct a graph of AS connectivity from which routing loops may be pruned and some policy decisions at the AS level may be enforced. BGP-4 provides a new set of mechanisms for supporting classless interdomain routing. These mechanisms include support for advertising an IP prefix and eliminate the concept of network "class" within BGP. BGP-4 also introduces mechanisms, which allow aggregation of routes, including aggregation of AS paths. BGP also performs interdomain routing in TCP/IP networks. Problems in BGP I-BGP Scaling Problem: All BGP speakers within a single AS must be fully meshed so that any external routing information must be re-distributed to all other routers within that AS. This "full mesh" requirement clearly does not scale when there are a large number of IBGP speakers as is common in many of todays internet networks. For n BGP speakers within an...

...TOPICS IN AD HOC AND SENSOR NETWORKS Simulations in Wireless Sensor and Ad Hoc Networks: Matching and Advancing Models, Metrics, and Solutions Ivan Stojmenovic, University of Birmingham and University of Ottawa ABSTRACT The objective of this article is to give advice for carrying out a proper and effective simulation activity for protocol design. It challenges some of the existing criticisms of simulation practices that emphasized validation aspects. This article advocates the use of simple models, matching assumptions and metrics in the problem statement and simulation to provide a basic “proof of concept,” and comparison with truly competing solutions, which is possible only after a thorough and critical literature review. Then the complexity of the models can be increased (one parameter at a time), revising the algorithms themselves by adapting them to new assumptions, metrics, and the corresponding simulation environment. Selected independent variables should explain performance under a wide range of scenarios. unclear which protocol will perform well under a wide range of scenarios. It is our view that each article should be judged on its overall contribution, including the assumptions used, theory developed, new algorithms introduced, protocol details, simulation results, and relevance to an ultimate goal of staying on a path toward creating applications. We begin with a literature review of existing criticism for simulation practices, and then discuss what we...

...for OLSR Routing Protocol in MANET Kirti Aniruddha Adoni1 and Radhika D. Joshi2 1 Modern College of Engineering, Shivaji Nagar, University of Pune, , India akirti2008@gmail.com, k_adoni@rediffmail.com 2 College of Engineering, University of Pune, India rdj.extc@coep.ac.in ABSTRACT Mobile Adhoc Network (MANET) eliminates the complexity associated with an infrastructure networks. Wireless devices are allowed to communicate on the fly for applications. It does not rely on base station to coordinate the flow of the nodes in the network. This paper introduces an algorithm of multipath OLSR (Optimized Link State Routing) for energy optimization of the nodes in the network. It is concluded that this solution improves the number of nodes alive by about 10 to 25% by always choosing energy optimized paths in the network with some increase in normalized routing overheads. KEYWORDS OLSR, multipath, Energy Optimization, Nodes Alive, Overheads 1. INTRODUCTION A Mobile Adhoc NETwork (MANET) is a multi-hop, distributed and self configuration network[1].The communication between two distant nodes is through the number of intermediate nodes which relays the information from one point to another. As nodes can move randomly within the network, routing packets between any pair of nodes become a challenging task. A route that is believed to be optimal for energy utilization at certain time might not be optimal at all, few moments later.[4] Traditional proactive routing protocols[3...

D'Souza National Institute of Technology Karnataka, Surathkal, India Johny Jose National Institute of Technology Karnataka, Surathkal, India ABSTRACT Delay Tolerant Networks (DTNs) have evolved from Mobile Ad Hoc Networks (MANET). It is a network, where contemporaneous connectivity among all nodes doesn’t exist. This leads to the problem of how to route a packet from one node to another, in such a network. This problem becomes more complex, when the node mobility also is considered. The researchers have attempted to address this issue for over a decade. They have found that communication is possible in such a challenged network. The design of routing protocol for such networks is an important issue. This work surveys the literature and classifies the various routing approaches. discontinuity in the network. There are also methods that have employed additional mobile nodes, to provide better message delivery. Researchers are even exploring how the social interaction of humans can be utilized for routing in a DTN. This survey has made an extensive study of the various routing strategies taken by the researchers in the past few years. We have classified them based on the type of knowledge used for routing. 2.

...selforganization wireless communication network through multi-hop relay. Thus it authentically achieves the purpose of ‘monitor anywhere and anytime’. The basic function of sensor network is gathering and sending back the information of the monitoring areas which the relevant sensor nodes are set in. But the sensor network node resources are very limited, which mainly embodies in battery capacity, processing ability, storage capacity, communication bandwidth and so on. Because of the limited monitoring range and reliability of each sensor, we have to make the monitoring areas of the sensor nodes overlapped when they are placed in order to enhance the robustness and accuracy of the information gathered by the entire network. In this case, certain redundancy in the gathered data will be inevitable. On the way of sending monitoring data by multi-hop relay to the sink nodes (or base stations) which are responsible to gather the data. It is necessary to reduce the redundant information by fusion processing. Data fusion is generally defined as a process that lots of data gathered from multiple sources or information are processed and combined in order to achieve more efficient data and ones that can better meet the requirements of the users. In most applications of wireless sensor network, sometimes we only concern about the monitoring results rather than gathering a lot of original data. Data fusion technology is an efficient method...

TCP provides reliable, ordered, error-checked delivery of a stream of octets between programs running on computers connected to a local area network, intranet or the public Internet. It resides at the transport layer. Web browsers use TCP when they connect to servers on the World Wide Web, and it is used to deliver email and transfer files from one location to another. HTTP, HTTPS, SMTP, POP3, IMAP, SSH, FTP, Telnet and a variety of other protocols are typically encapsulated in TCP. Applications that do not require the reliability of a TCP connection may instead use the connectionless User Datagram Protocol (UDP), which emphasizes low-overhead operation and reduced latency rather than error checking and delivery validation.

...On the State of IP Spoofing Defense TOBY EHRENKRANZ and JUN LI University of Oregon 6 IP source address spoofing has plagued the Internet for many years. Attackers spoof source addresses to mount attacks and redirect blame. Researchers have proposed many mechanisms to defend against spoofing, with varying levels of success. With the defense mechanisms available today, where do we stand? How do the various defense mechanisms compare? This article first looks into the current state of IP spoofing, then thoroughly surveys the current state of IP spoofing defense. It evaluates data from the Spoofer Project, and describes and analyzes host-based defense methods, router-based defense methods, and their combinations. It further analyzes what obstacles stand in the way of deploying those modern solutions and what areas require further research.
