摘要：The execution and survival of ad hoc networks depends on cooperative and trusting nature of the distributed nodes. There is a common assumption in the routing protocols that all nodes are trustworthy and cooperative. However, this na.ve dependency on intermediate nodes makes the ad hoc networks vulnerable to passive and active attacks by malicious nodes. To enhance security in ad hoc networks, it is important to evaluate the trustworthiness of other nodes without central authorities. A considerable amount of work has been done on trust based routing. Yet there are some issues which are not addressed clearly in the existing papers. These issues are like concept of malicious node/selfish node, calculation of trust, concept of central trust authority, proactive nature of calculation and lack of security model for cryptographic analysis of trust based routing. If these issues may be taken care of then an efficient and robust trust based protocol can be developed.
