Multipath routing protocols enhance the lifetime of the wireless sensor networks by distributing traffic among multiple paths instead of a single optimal path. Transmission of secured data is also an important research concern in the wireless sensor networks. In this paper, a secure node disjoint multipath routing protocol for wireless sensor networks is proposed. Here, the data packets are transmitted in a secure manner by using the digital signature crypto system. It is compared with an ad hoc on-demand multipath distance vector routing protocol. It shows better results in terms of packet delivery fraction, energy consumption, and end-to-end delay compared to the ad hoc on-demand multipath distance vector routing. © 2012 IEEE.Data packetDistance vector routingDistance vector routing protocolsEnd to end delayEnergy efficient routing protocolMultipath routing protocolsMultiple-pathNode-disjointNode-disjoint multipath routingOperational lifetimeOptimal pathsPacket DeliverysecurityAuthenticationCryptographyEnergy utilizationMobile telecommunication systemsRouting protocolsWireless sensor networksSensor nodes
