LSR Protocol Based on Nodes Potentiality in Trust and Residual Energy for WSNs

In Wireless Sensor Networks (WSNs), all the nodes selected for packet routing must be trustworthy, andat the same time energetic too. Smooth conservation of nodes energies and the trust levels, are an important issues in WSN because they directly affects the life span and reliability of the nodes as well as the entire network. The energy utilization at every node must be very smooth and at the same time, packets should be forwarded via trusted nodes only. In this paper, we propose an Energy Efficient LinkState Routing Protocol (EELSRP) using the potential nodes selected by applying the fuzzy logic on the trust and residual energy levels. This routing protocol finds the best route by balancing the nodes residual energies and trust levels, and protects the WSN against routing attacks by eliminating the untrusted nodes before the creation of route.
