Wireless sensor networking has been a subject of extensive research efforts in the recent years, and has been well recognized as a ubiquitous and general approach for some emerging applications such as a real-time traffic monitoring, ecosystem and battlefield surveillance. Since these networks deal with sensitive data, it is imperative that they are made secure against various types of attacks such as node capture, physical tampering, eavesdropping, denial of service etc. This paper presents a secure routing mechanism for wireless sensor networks. The protocol is resilient in the presence of malicious nodes that may launch selective packet dropping attack on the routing path. The scheme employs single-path routing, and therefore, it is energy-efficient. While the packets are forwarded towards the base station, if any node fails to forward a packet, it is isolated immediately. Packets are then routed around the node. Simulation conducted on the scheme clearly demonstrates that it is more efficient than some of the existing similar schemes.
