Hybrid Communication Method for Data Gathering in Wireless Sensor Networks
When cluster heads transmit their data to the sink via multi-hop communication, the cluster heads closer to the sink are burdened with heavy relay traffic and tend to die early. On the contrary, if all cluster heads transmit datas to the sink via single-hop communication, the cluster heads further from the sink will die much more quickly than those closer to the sink. In this paper, we first develop an analytical model to derive the optimal cluster radius. Then we propose a hybrid communication method where the nodes can transmit data to the sink in either single-hop or multi-hop. Finally, we conduct extensive experiments and show that our method outperforms LEACH and HEED in terms of network lifetime by balancing energy consumption.
