Recent advances in ad-hoc networks

Due to rapidly growing impact on lightweight wireless devices as well as evolution of wireless communications, the Ad-Hoc network technologiesare gaining effort in increasing number of widespread applications. Ad-hoc networks can be used anytime, anywhere, autonomous with cost effective and limited or no communication infrastructure. The preceding infrastructure is fancy or annoying to use. The ad-hoc networks can be classified according to their application such as Mobile Ad-hoc NETwork (MANET), Vehicular Ad-hoc NETwork (VANET), Wireless Sensor Network (WSN) and Wireless Mesh Networks (WMN). MANET is a self-organizing infrastructure less personal area network of mobile devices communicated with wireless link. VANET uses travelling cars as nodes in a network to create a mobile network. WSN consists of autonomous sensors to control the environmental actions from a remote location. WMN is made up of radio nodes in a mesh topology. The potential applications of the Ad-Hoc networks are tactical networks, crisis management services, commercial and civilian environments, home and enterprise networking, coverage extension, education, game theory and business environment, entertainment, sensor networks, context aware services, provincial level, backup services and Bluetooth. The major design challenges and the characteristics of the Ad-Hoc networks are limited battery power, autonomous devices, device heterogeneity, limited bandwidth, network scalability, security, dynamic network topology, routing, resource discovery, no fixed access point (i.e. infrastructure less), contrary environment and irregular connectivity. This talk will focus on various design challenges, issues and applications of the Ad-hoc networks. Meeting these requirements on ad-hoc networks architecture can support a wide range of network applications. Further, few designed protocols on Ad-Hoc networks also will be discussed.
