Design and implementation of high event density area centered clustering based routing

Energy consumption is the most important issue in a wireless sensor network (WSN). As the WSN scale increases, the required energy consumption and bandwidth are increased. In this paper, we propose high event density area centered clustering based routing (HEDACR) for efficient energy consumption in WSN. HEDACR forms a high density tree based cluster centered at the high event density area. The main idea of HEDACR is to form a multi-hop short distance routing path and for all sensors to participate in the data transmission to diffuse energy consumption for data transmission. We developed the environmental data gathering and aggregation sensor (EGAS) to realize HEDACR. We experimented on HEDACR in a test bed. The result of experiment indicates that HEDACR reduces the energy consumption and extends the network lifetime as compared with LEACH using one-hop.
