A Mobile Ad hoc wireless NETwork (MANET) consists of a number of wireless mobile nodes that are capable of communicating with each other without the use of a network infrastructure or any centralized administration. In such a network, each mobile node operates not only as a host but also as a router, forwarding packets for other nodes that may not be within the direct wireless transmission range. Thus, nodes must discover and maintain routes to all other nodes. Due to the mobility of the nodes, routers for MANETs need to be dynamically renovated to reflect the changes in topology. Therefore, the design of the routing protocols for such networks is more challenging than that for wired networks.
