The wireless sensor network transferring packets with the valid information via a single-path routing is more vulnerable to the malicious sniffing attack which tries to eavesdrop on the valid information. In this paper, we propose a multi-path secure routing protocol for ad-hoc wireless sensor networks transferring packets which include parts of the valid information to the sink node through the multiple-paths against sniffing. Transferring packets with parts of the valid information over the multiple-paths significantly reduces the risk of the eavesdropping on the valid information. The enhanced security and the energy efficiency of the proposed multi-path routing protocol are shown by the simulated results using the NS-2 by comparing with single-path routing protocol.
