Ali Journal On Wireless Communication Networks 2320 - 2351 5 4 1 9 Wireless Sensor Network (WSN), AODV, DSDV, OLSR, QoS, Link Reliability In this paper, the author has proposed a new route next-hop selection algorithm for Wireless Sensor Networks (WSNs) that is aimed towards reducing packet loss, end-to-end delay, and energy consumption. In this proposed algorithm, the forwarding nodes are selected through hop-by-hop estimation of QoS, and residual energy. The efficiency of the proposed routing algorithm is evaluated by using the NS-2 simulator. The simulation results show that the proposed algorithm provides a significant improvement in terms of energy consumption, the number of packets forwarded, an end to end delay, and packet delivery ratio compared to the existing routing protocol.
