The rapid expansion of wireless sensor networks technology has created an unprecedented opportunity to gather and extract information from wireless sensor networks. How to gather sensed information in energy efficient way is critical problems recently. Clustering technique has been proven to be an effective approach for data-gathering in wireless sensor networks. However, in a mobile environment, the dynamic topology poses the challenge to design an algorithm for data-gathering. In this paper, we propose a novel cluster formation algorithm, namely PPD algorithm according to considering the ene...
