Abstract

In wireless sensor networks, considering the problems of network congestion and unreliable transmission of data packets caused by large numbers of data transmission in monitoring abnormal events, this paper proposed a reliable transmission routing protocol(RTRPT) based on trust mechanism. The protocol proposed a gradient clustering model to select cluster head nodes. When no abnormal events occurred, the nodes identified the neighbor nodes for data transmission by forwarding energy threshold. At the same time, it calculated the forwarding probability and historical trust degree of these nodes to obtain the direct trust degree, and then obtained the indirect trust degree through the interactive indirect evaluation of these nodes. Then this protocol used direct trust degree, indirect trust degree, distance measurement and residual energy as evaluation indexes. After quantification, it obtained the comprehensive trust of neighbor nodes by the entropy weight method. When abnormal events occurred, the nodes only needed to select the neighbor nodes with the highest comprehensive trust as the forwarding node, then established the routing path. In the simulation environment, compared with TSRP and ESRT, RTRPT reduced the packet loss rate of nodes by 69.4% and 52.7% respectively. The node transmission delay reduced by 53.6% and 34.8% respectively. The network life cycle extended by 32.5% and 15.7% respectively. Simulation results show that RTRPT can effectively decrease packet loss, reduce transmission delay and prolong life cycle.
