Distributed Cluster Based Routing Technique with Multiple Sinks for Wireless Sensor Networks

Problem Statement: In order to reduce or minimize energy consumption and to improve bandwidth utilization in Wireless Sensor Networks (WSN), it was essential to consider its architecture in the network topology, power consumption, data rate and fault tolerance. Our objective is to formulate an effective cluster formation of nodes with multiple sinks to reduce power consumption and minimize the data loss. Approach: In this study, we propose to design a distributed cluster based routing technique in which multiple sinks were deployed. Initially the average distance between the sensor nodes and the sink was calculated and the nodes send their location information to the neighboring sinks. The sinks were updated this information at every time interval. The optimal sink places could be found using the global information based method. After sinking deployment, the information of each cluster was transmitted to other cluster using a gateway. The information gathered by the sink was transmitted to other clusters using a gateway. Results: By simulation results, we show that our proposed technique was enhanced the packet delivery ratio while reducing the energy consumption and delay. Conclusion: Our proposed approach minimizes the power consumption and data losses.
