A New Polling Protocol with Efficient Cluster Creation for WSN

Recently, wireless sensor network is widely used. The deployment of WSN in the field, however, is still restricted due to limited energy supply, limited computing power, limited buffer size, and packet delay. In this paper we present a new cluster model and polling protocol integrating the schedule polling and low power listening scheme. The new clustering approach allows short routing between the sensor nodes towards the base station. Also, the polling protocol uses smaller time slot resulting in shorter delay for data transmission. This significantly reduces the energy consumption of the cluster. The simulation results demonstrate that the proposed scheme can effectively reduce the delay and prolong the lifetime of the network.
