Fixed Partitioning Methods for Extending lifetime of sensor node for Wireless Sensor Networks

ABSTRACT WSN based on wireless sensor nodes, Sensor nodes can not be reassigned and recharged if they once placed. Each sensor node comes into being involved to a communication network with its limited energy. But the existing proposed clustering techniques, being applied to WSN environment with irregular dispersion of sensor nodes, have the network reliability issues which bring about a communication interruption with the local node feature of unbalanced distribution in WSN. Therefore, the communications participation of the sensor nodes in the suggested algorithm is extended by 25% as the sensor field divided in the light of the non-uniformed distribution of sensor nodes and a static or a dynamic clustering algorithm adopted according to its partition of sensor node density in WSN. And the entire network life cycle was extended by 14% to ensure the reliability of the network. 키워드 : 계층적 라우팅 구조, 고정 클러스터링, 동적 클러스터링, 정적클러스터링 Key word : Hierarchical Routing Structure, Fixed clustering, Dynamic clustering, Static Clustering
