Abstract

A Mobile adhoc network is a self-organized multi hop system comprised by multiple mobile wireless nodes with peer-to-peer relationships. It is vulnerable to attacks from malicious nodes since there is no centralized administration and interactive so the qualities of overall networks are also easily affected. In this connection, this paper proposes trust based routing protocol using fuzzy logic rules prediction method. It eliminates the untrustworthiness nodes in order to obtain a reliable path between the source and the destination. The proposed trust based routing algorithm is a new Multipath proactive routing protocol on the basis of the multipath OLSR. The simulation result shows that the proposed protocol effectively detects the malicious nodes and guarantee higher packet delivery ratio and throughput compare with secure multipath OLSR (SMP-OLSR).
