Abstract: Wireless Sensor Networks are basically employed for critical tasks whose operation is of prime importance. The sensor nodes are deployed in an environment where human intervention is not possible most of the times. The deployment of sensor nodes in habitat monitoring, health care, military fields demands that security to be in place because the data being handled is highly confidential. Wireless sensor networks are vulnerable to a wide set of attacks which threaten the network operation. The routing procedure employed in wireless sensor networks must be capable of preventing the data integrity loss that results out of the both active and passive attacks. In addition to the network being secure, trust establishment at various points at which the data is transmitted and energy awareness is essential to have high network lifetime. Networks are highly constrained in resources such as memory, processing capabilities and energy. This resource constraint is a rigid obstacle against applying traditional security mechanism like cryptographic solutions which need too much processing power and thus leading to heavy energy consumption. The limited energy resources on sensor nodes make them an attractive target for the attackers. Our proposed protocol caters to include trustworthiness and energy awareness by including a trust model that includes both direct and indirect trusts. The proposed protocol safeguards a wireless sensor network from intruders by considering the trustworthiness of the forwarder node at every stage of multi-hop routing. Increases network lifetime by considering the energy level of the node, prevents the adversary from tracing the route from source to destination by providing path variation. The protocol is built on NS2 Simulator. Experimental results show that the protocol provides energy balance through establishment of trustworthy paths from the source to the destination.
