A secure alternate path routing in sensor networks

This paper presents a secure alternate path routing in sensor networks. Our alternate path scheme makes the routing protocol resilient in the presence of malicious nodes that launch selective forwarding attacks. SeRINS (a Secure alternate path Routing IN Sensor networks) detects and isolates the compromised nodes, which try to inject inconsistent routing information, from the network by neighbor report system. In neighbor report system, a node’s route advertisement is verified by its surrounding neighbor nodes so that the suspect node is reported to the base station and is excluded from the network. Simulation experiments show that SeRINS is resilient in the presence of several compromised nodes which launch selective forwarding attacks, and robust by excluding the compromised nodes which inject inconsistent routing information from the network. 2006 Elsevier B.V.
