Now, an ad hoc network works well rely on other nodes in the network for discovering route and forwarding data packets. Most routing protocols are based on the assumption of cooperation and no cheat. If there are malicious nodes to attack network, these protocols would be broken down. In this paper, we propose the cooperative on-demand secure route (COSR) protocol to against the main passive route attacks. COSR measures node-reputation (NR) and route-reputation (RR) by contribution, capability of forwarding (CoF) and recommendation to detect malicious nodes. Furthermore, COSR uses reputation to balance load to avoid hot-point in the network. In this paper, we provide definition and formula of NR and RR. Moreover, we present improvement of DSR by reputation model to discover optimum route
