무선 센서 네트워크를 위한 에너지 인식 하이브리드 클러스터링 = An Energy Aware Hybrid Clustering for Wireless Sensor Networks

다국어 초록 (Multilingual Abstract)

Many studies for the efficient utilization of node energy in wireless sensor networks has been done because sensor nodes operate with limited power based on battery. Existing cluster structure has problem that energy consumption is unbalanced because energy consumption is concentrated in cluster head. And in case distribution density of sensor node is low, the energy efficiency is declined because only a few members exist in cluster. In this paper, we submit an hybrid clustering mechanism to construct topology by mixing cluster structure and mesh structure selectively according to distribution of sensor nodes to improve energy efficiency. And we attempt to derive balanced energy consumption by selecting cluster head considering residual energy of each node. The performance of the proposed mechanism has been examined and evaluated with the NS-2 simulator in terms of network lifetime and end-to-end delay.
