...ufpe.br∗ , jean@uag.ufrpe.br† The remainder of this paper is organized as follows. Section II provides an overview about mobile clouds and the analytical modeling for availability evaluation. The methodology adopted is presented in detail in Section III. Section IV presents the models developed to represent a mobile cloud system. A case study is described in Section V, with the results obtained through model analysis. Section VI concludes the paper, presenting also some possible future works. II. BACKGROUND Abstract—Mobile cloud computing refers to abstraction of computational power to outside of the mobile device, processed in the “clouds”. This paper provides an availability and energy consumption study using hierarchical heterogeneous modeling. Different scenarios were analyzed considering wireless communication technologies, such as 3G and WiFi. The results shows that the 3G protocol causes a lower availability and is the greater responsible for the discharge of battery, but when is combined with WiFi protocol providing communication redundancy, we have the best results of availability and better results of uninterrupted operation time of battery. I. I NTRODUCTION In the last years, the tech industry has showed a special interest in cloud computing and mobile devices. Cloud computing enables the use of computing resources by means of providers that may be in any geographic location, accessible through de Internet, i.e., in the clouds [1]. In parallel with the advance...

...Evil Twin Wi-Fi Attacks NT1110: Computer Structure and Logic October 23, 2013 Abstract What is the “Evil Twin”? Evil Twin is a type of Wi-Fi attack, it is a home-made wireless access point that masquerades as a legitimate hot spot with a very strong signal in efforts to gather personal or corporate information. With this, the overall goal of this report is to educate the public on how to protect themselves. Additionally in this disadvantages and advantages will be discussed along with the effects on consumers and the future. According to Dr. Phil Nobles, a wireless Internet and cybercrime expert at Cranfield University, said: this is how the evil twin works. "So-called 'evil twin' hotspots present a hidden danger for Web users. In essence, users think they've logged on to a wireless hotspot connection when in fact they've been tricked to connect to the attacker's unauthorized base station. The latter jams the connection to a legitimate base station by sending a stronger signal within close proximity to the wireless client -- thereby turning itself into an 'evil twin. Cybercriminals don't have to be that clever to carry out such an attack. Because wireless networks are based on radio signals they can be easily detected by unauthorized users tuning into the same frequency."

...Wireless Technology in Business Many varieties of wireless communication are available today; and many are even tailored for business application. The two technologies that Team B recommends are cellular communication and WIFI. These are two markets that are reaching to expand accessibility and creating new applications to mobilize our business. Through the WIFI on our phone we are able to send picture of designs for new paper products. We can tailor presentations for our target audience and with our WIFI we can show them almost anywhere especially if a client has access to a smart phone. Through these forms of wireless technology our business has the ability to go global. Pros Some benefits of the technologies are as follows. One, cellular technology creates the most efficient form of communication within the company, by keeping employees focus on work while they are communicating since they are using company property. Two, it streamlines the process of exchanging important information in the digital form. Simply put this form is the easiest method of exchanging important information like documents, contracts, and or emails. Therefore having WIFI technology available within the company the process of communication is much quicker and easily accessible. WIFI technology also benefits a company’s workspace because an employee does not have to work in one specific place based on location of the internet hard line points. It allows employees to move around and still be able to...

...Case Study 2: Wireless and Mobile Technology By Terry Boone Dr. Stevens CIS 500: Information Systems for Decision Making 5/24/2014 Wireless and mobile technologies have transformed our daily lives, and also made a huge impact on the business world. The definition of the terms wireless and mobile technologies are often used interchangeably; however, this is not the case. Wireless technology is the ability to communicate on the internet via devices without a wire. Mobile technology is the ability to communicate on the internet via wireless and over a wired connection. Mobile technology allow for a user to access the internet anywhere at any time; conversely, wireless technology is only limited to the broadcast area emanating from the router and modem combination. Businesses use wireless and mobile technologies to increase efficiency by saving money on installation costs freeing up funding to be used elsewhere. Businesses can use wireless technology to connect employees throughout building, but still be connected to important software that runs the businesses operations through portable devices. Cell phones, laptops, and tablets in conjunction with wireless technologies have created the possibility for employees to become more powerful. Smaller organizations must maximize the efficiency of workers, so they can compete. Small organizations must ensure that employees are always connected, in addition to not being tied down to a single location (Koose, n.d.). Smart phones...

According to the recently released September 2012 edition ofHotel Horizons®, PKF Hospitality Research, LLC (PKF-HR), is forecasting that on any given night in 2012, nearly 3.0 million of the nation’s 4.8 million hotel rooms will be occupied. This is 5.6 percent greater than the levels of lodging demand accommodated in 2007, the year prior to the great industry recession. RevPar: Revenue per available room * Shift from high-end and branded hotels to more economical options: Countries in or highly connected to the Eurozone face an uncertain short-term outlook and are likely to see stagnant or negative GDP growth, depending on the outcome of the sovereign debt crisis. Many other developed and major emerging markets are expected to experience modest growth. => tourists from Europe and emrgeing markets look for cheaper accomodation while traveling. -Long term growth: The industry is expected to continue to grow rapidly in the long term.

...opportunity. It is how technopreneur has their vision and thinking to make the future world even better. Nowadays, the technology are growing rapidly likes smart phone, tab or laptop to help people in communication to become better. Most of the people in town are benefits with these technology but in contrast, the rural areas are still unable to benefit from this technology. This is due to the deficiency of resources and knowledge about it. There are lacks of server and cable network to build in the urban area as this may cost a lot of money to develop. The broadband also unstable in network services to those in urban area and people at there may suffer the slow speed internet connection when they surf the internet. In the new era with technology, it should not discriminate between town or rural area to own a better living life. The technology of internet services should continue developing in urban area so that the all people can enjoy share the information technology knowledge. First of all, to tackle the problem of internet services, a product likes long range wifi router can be built in the rural area to provide the internet services. The long range wifi router should has a solar energy feature so that it can save the power supply. It also includes a backup power function during the cloudy or raining days. This technology can save the direct power usage by using solar energy. After the wifi router is success build up, the signal is passed to the satellite and finally the...
