With the increasing usage of mobile devices to ubiquitously access heterogeneous applications in wireless Internet, the measurement and analysis of Internet traffic has become a key research area. In this paper, we present the results of our measurements for VBR traffic over UDP in 802.11g and GPRS networks. We focus on Inter-Packet Arrival Time (IPRT) and Inter-Packet Transmission Delay (IPTD)...

Computer networks are used for the easy sharing of data and resources within a closed user group. These networks find use in a plethora of scenarios. This paper describes an App in Android which enables the android devices in a particular Wi-Fi network to join a private wireless network such as an office. Users entitled to use this particular app can share messages and data without using any pa...

Wi-Fi fingerprinting is widely used for indoor positioning and indoor navigation due to the ubiquity of wireless networks, high proliferation of Wi-Fi-enabled mobile devices, and its reasonable positioning accuracy. The assumption is that the position can be estimated based on the received signal strength intensity from multiple wireless access points at a given point. The positioning accuracy,...

The fast growing of mobile Internet users with the ability of using a wide diversity of access technologies such as Wi-Fi, WiMAX and UMTS/LTE, and the increasing proliferation of mobile devices with heterogeneous network interfaces, require versatile mobility mechanisms providing seamless roaming across those access technologies. Mobility agents such as Mobile IP and Fast MIPv6 are common, howe...

The Internet of Things (IoT) – connection of small smart sensors, actuators and other devices to the Internet – is a key concept within the smart home. To ease deployment, such devices are often wireless and battery powered. An important question is the wireless interface used. The ubiquity of WiFi in homes today makes this an attractive option, but the relatively high power requirements of Wi-...

The convergence of wireless mobile technologies and Internet allows compelling possibilities for future applications due to the new advancement, constantly growing and personalized services in the mobile communication. 3G (third generation) and Wi-Fi are major wireless technologies that are used by most people today. The two most important phenomena impacting telecommunications over the past de...

background: the use of devices emitted microwave radiation such as mobile phones, wireless fidelity (wi-fi) routers, etc. is increased rapidly. it has caused a great concern; the researchers should identify its effects on people's health. we evaluated the protective role of vitamin c on the metabolic and enzymatic activities of the liver after exposure to wi-fi routers. material and methods: 70...

We present a framework for monitoring enterprise wireless networks using desktop infrastructure. The framework is called DAIR, which is short for Dense Array of Inexpensive Radios. We demonstrate that the DAIR framework is useful for detecting rogue wireless devices (e.g., access points) attached to corporate networks, as well as for detecting Denial of Service attacks on Wi-Fi networks. Prior ...

Wireless networks have become so ubiquitous that researchers all over the world have come up with various security protocols to ensure confidentiality and integrity of data as well as availability of resources. IEEE 802.11 task group drafted a new wireless security protocol known as robust security network (RSN circa 2009) erstwhile Wi-Fi alliance came up with Wi-Fi Protected Access (WPA). The ...
