Ten billion. That’s how many mobile devices will populate our planet by 2017. 1 This rapid proliferation in mobility is increasing the need for wireless connectivity. Many organizations are responding to this trend by providing Wi-Fi access to employees and guests, which presents many opportunities but also poses new threats to the network. Savvy mobile users can set up wireless networks just b...

To address deployment schemes over large dispersed geographical area a paradigm shift in the technology was needed. Wireless Mesh Networks (WMN) has emerged as a promising technology to such challenging tasks. As wireless network grows it puts an increased demands in infrastructure based networks.802.11s based WMN is a concrete step that address this paradox to make infrastructure itself wirele...

Smart homes have gained a lot of attention in recent years. People are looking forward to receiving an opportunistic network, where they can gather communication devices within a wireless heterogeneous network. The most important issue in a wireless heterogeneous network is to manage bandwidth, due to the scarcity of this resource in wireless links, compared to wired networks. Bandwidth managem...

Push-to-Talk (PTT) is a service that allows users using mobile phones in a way like walkie-talkie. All big telecommunication vendors and operators consider PTT an emerging application. 3GPP and OMA regulate the PTT specifications on the basis of Session Initiation Protocol (SIP) to assure interoperability. However, current PTT services are dedicated to cellular phones. We would like to realize ...

Many studies have demonstrated that Wireless Fidelity (Wi-Fi) networks can detect human behavior due to the development of wireless devices and detecting methodologies. Human activity recognition applied Channel State Information (CSI) in commercial Wi-Fi devices, which has many practical applications. This paper aims present a method for recognizing uses enhanced Wi-Fi-based CSI signals. At fi...

Testing and evaluating the performance of actual software for wireless networks is difficult. Real-world wireless testbeds are costly and cumbersome to maintain. Measurement studies are complicated by many uncontrollable environmental influences, particularly the wireless channel. Network simulations on the contrary allow the convenient analysis of wireless networks with a maximum level of cont...

Thousands of enterprises worldwide are cutting the wires to their local area networks (LANs) to enjoy greater productivity from their unwired work force. Many wireless networking systems were established to manipulate urban networks in order to provide internet, data and video etc. connectivity. A significant drawback of traditional Wi-Fi system based on IEEE 802.11b standard is that they are q...

Next generation wireless communications will likely rely on integrated networks consisting of multiple wireless technologies. Hybrid networks based, for instance, on systems such as WMAN and WLAN can combine their respective advantages on coverage and data rates. WLAN is provided in hotspots, places like coffee bars, airports, shopping centers etc. where the hotspots are covered by access point...
