Grid based data dissemination protocol for mobile sink in wireless sensor network

Abstract

Life time and Energy Efficiency are important factors in the design of wireless sensor network. A critical issue during data collection is the formation of energy holes near the sink. Sensors near the sink have to participate in relaying data on behalf of other sensors and thus their energy will be depleted very quickly. The mobile sink movement yields the significant performance gained through decreasing the amount of energy consumption. In this study, we propose a Grid Based approach for Data Disseminating to the Mobile Sink in Wireless Sensor Network. Mapping the position of nodes and sink to virtual grid infrastructure construct our main contribution. So that the data which is buffered by nodes could be disseminated to the mobile sink to the optimal manner. Finally, comprehensive simulation reveals the superiority of proposed algorithm in various scenarios.
