Abstract — The wireless sensor network (WSN) technology is a key component for ubiquitous computing. In order to achieve the long term operation of WSNs, communication protocols based on clustering have been extensively studied such as LEACH, ACE and HEED. In this paper, we propose clustering communication methods for WSNs. The features of our methods are: 1) the number of neighboring nodes is grasped with less communication overhead and 2) the radius of broadcast is determined based on the number of neighboring nodes. Thanks to those features, each cluster has almost even members and their energy consumption is smaller than conventional methods. We also extend the proposed method to a multi-hop communication version. The effectiveness of the proposed methods are demonstrated by numerical simulation.
