Abstract

Wireless Sensor Network (WSN) becomes familiar network where nodes are controlled in the presence of base station. In such case, nodes are communicated without the presence of base station. In this scenario, data gathering is a major challenge where nodes may get interrupted from external attackers. It leads to less network lifetime. In existing schemes, data gathering ratio is not improved highly without stable multicast routing scheme. In this research work, Scheduling based Stable Multicast Data Gathering Scheme (SSMDGS) is proposed for attaining balance between data gathering ratio and stability. It consists of three phases. In first phase, cluster construction and maintenance is implemented to support data gathering. Message creation time is estimated to reduce the overhead and delay. Energy is estimated before and after data gathering phase. The comparison of energy is done and maximum energy is attained after data gathering phase. Based on the extensive simulation results, SSMDGS achieves high data gathering ratio, energy efficiency, network lifetime, packet delivery ratio and low delay as well as overhead.
