A cooperative selection reactive routing protocol for wireless sensor networks

In Wireless Sensor Network (WSNs), routing protocol is an important aspect to utilize network resources fairly. Normally, routing mechanisms are selfish in nature and are based on a single objective criterion, e.g., hop count. This behaviour is inappropriate for a long lasting communication as it causes performance degradation in the entire network and ultimately leads to network congestion. To enhance network performance, we propose a Co-operative Selection Reactive Routing Protocol (CSRP) that cooperatively selects the End-to-End (ETE) route by considering the traffic load along with the hop count. We compared CSRP with AODV using ns-2.35 in terms of ETE throughput, ETE delay, and Packet Delivery Ratio (PDR). The results reveal that CSRP improves throughput by 20.95%, reduces delay by 18.65% and increases PDR by 56.41%.
