One of the greatest challenges in vehicular ad-hoc networks (VANET) is to establish stable routing. Due to dynamic network , keeping stable routing is a difficult problem. Therefore, trust-based stable routing (TBSR) protocol is proposed in this paper. The node is chosen to be next-hop node until it reaches to trust threshold. To evaluate the node trust, we introduce the node' role trust, interaction printer trust, and recommendation trust. Moreover, the Analytic Hierarchy algorithm is used to coalesce various recommendation opinions from neighbor nodes. The simulation results show that the proposed approach outperforms GPSR (greedy perimeter stateless routing) and OLSR (optimized link-state routing) in terms of throughput, average delay .
