摘要:Ad hoc wireless networks have emerged as one of the key growth areas for wireless networking and computing technology. Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. Most of the routing protocols in wireless ad hoc networks, such as DSR, assume nodes are trustworthy and cooperative. One of the major factors effecting the ad hoc communication is the misbehaving of nodes. Although an efficient power management scheme is applied to an ad hoc network, a misbehaving node may result in the improper routing of packet which may extend to the complete collapsing of the network also. Existing approaches such as economic incentives or secure routing by cryptographic means alleviate the problem to some extend with limitations. The main objective of this project is to cope with misbehavior. This paper task, address the question of how to enable a system to operate despite the presence of misbehavior in a mobile ad-hoc network. How the network can be functional for normal nodes when other nodes do not route and forward the packet correctly. In this paper an optimal routing protocol for misbehaving network called RMP (Route Management Protocol) to cope with misbehavior for ad hoc network is proposed. The protocol enables nodes to detect misbehavior by first-hand observation and use of second-hand information provided by other nodes. A fully distributed reputation system that can cope with false information and effectively use second information in a safe way is proposed. The approach uses a modified Bayesian estimation and classification procedure for the isolation of malicious and selfish node in a given network.
