摘要：Mobile Ad Hoc Network (MANETs) is a Collection of mobile nodes connected with wireless links MANET has no fixed topology as the nodes are moving constantly form one place to another place. All the nodes must co operate with each other in order to route the packets. Cooperating nodes must trust each ot her. In defining and managing trust in a military MANET, we must consider the interactions between the composite cognitive, social, information and communication networks, and take into account the severe resource constraints (e.g., computing power, energy , bandwidth, time), and dynamics (e.g., topology changes, mobility, node failure, propagation channel conditions). Therefore trust is important word which affects the performance of MANET. There are several protocols proposed based on the trust. This paper is a survey of trust based protocols and it proposes some new techniques on trust management in MANETs. In this paper , we propose a recommendation exchange protocol which builds a trust relationship between nodes in an ad hoc network. The trust is based o n previous individual experiences and on the recommendations of others . We present the Recommendation Exchange Protocol (REP) which allows nodes to exchange recommendations about their neighbors. At last, we analyze the performance of the REP protocol and show its scalability. We show that our implementation of REP can significantly reduce the number messages.
