In the next generation of wireless communication systems, there will be a need for the rapid

deployment of independent mobile users. Significant examples include establishing survivable, efficient,

dynamic communication for emergency operations, disaster relief efforts, and military networks. Such

network scenarios cannot rely on centralized and organized connectivity, and can be conceived as

applications of mobile ad hoc networks. A MANET is an autonomous collection of mobile users that

communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the

network topology may change rapidly and unpredictably over time. The network is decentralized, where

all network activity including discovering the
