PADCP: Power-aware dynamic clustering protocol for wireless sensor network

The energy consumption is the most important issue in the wireless sensor network. In order to extend the lifetime of the wireless sensor network, clustering technique is considered as an effective way to achieve the power conservation, network scalability, and load balance. In this paper, we present a low energy clustering network architecture PADCP to prolong the network lifetime and to improve the performance of transceiver by adding several adaptive schemes: dynamic cluster range, dynamic transmission power, and cluster-heads re-election. Besides, our PADCP also improves the load balance when the sensor nodes are non-uniform dispersion. In addition, the mobility of die sensors is also taken into consideration in this paper. The experimental result proves that our proposed method is effective in saving power and load balance.
