Mobile Ad hoc NETwork (MANET) is infrastructure less networks of mobile nodes linked with wireless connectivity (Corson and Macker, 1999), which are dynamic in nature, to transfer data. Wireless mobile networks based on cellular concept depends on infrastructure support of base stations which acts as access points to the mobile devices to route messages to and from mobile nodes in specified transmission area. WLAN, GSM, WLL etc are wireless networks based on this concept. Whereas MANET does not require any pre-existing fixed network infrastructure; centralized message passing device is not required for communicating between mobile nodes.
