The emergence of powerful hand held devices like cell phones, personal digital assistants (PDA), pagers coupled with the advancement of wireless communication system have paved the way for a variety of mobile computing and wireless networking technology recently. The history of wireless networking goes to early days Defense Advanced Research Projects Agency packet radio network. The advantage of wireless networking is its ability to support user mobility and has created a new breadth to problem solving in this domain, resulting in unpredictable resource requirement and uncertainty in network connectivity. Solutions to these problems have boosted the market for wireless services. Wireless ad hoc network is a collection of mobile devices forming a network without any supporting infrastructure or prior organization. Nodes in the network should be able to sense and discover with nearby nodes. Due to the limited transmission range of wireless network, multiple network "hops" may be needed for one node to another (source to destination or intermediate node) across the network. There are number of characteristics in wireless ad hoc networks, such as the dynamic network topology, limited bandwidth and energy constraint in the network. Mobile ad hoc network plays an important role in different applications such as military operations to provide communication between squads, in emergency cases in out-of-the-way places, in medical control etc. Routing protocols play a significant role in the implementation of mobile ad hoc networks (MANET). Due to the characteristics of mobility of ad hoc networks it is crucial to find a path or route from the source to the destination node and perform the communication between nodes for a long period of time. In MANET, a number of routing protocols using a variety of routing algorithms has been proposed - for example Dynamic Source Routing (DSR), Ad hoc On demand Distance Vector Routing (AODV), Temporally Ordered Routing Algorithm (TORA), Lo
