A mobile ad hoc network (MANET) is a collection of mobile nodes that can instantly establish a network, whenever they coexist in the same neighbourhood without the need of any fixed infrastructure or centralized administration. The role of routing protocols in an ad hoc network is to allow the source to find routes to destination with the cooperation of other nodes. Due to the arbitrary movement of the nodes, the network topology changes rapidly and randomly. Hence the routing protocol must also be able to react to these changes and must enable the nodes to identify new routes to maintain connectivity. The problem of security in MANETs(2)(3) represents a serious challenge. This is primarily due to the high dynamic nature of the ad hoc network and due to the need to operate efficiently with limited resources, including network bandwidth and the CPU processing capacity, memory and battery power (energy) of each individual node in the network. Rapid and frequent routing protocol interaction between nodes is required. Expensive and cumbersome security mechanisms can delay or prevent such exchanges of routing information, leading to reduced routing effectiveness, and may consume excessive network or node resources leading to many new opportunities for possible Denial-of-Service (DoS) attacks through the
