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...
This paper proposes self-deploying approaches for sensor networks. The gravitational field (GF) and the radioactive decay (RD) are used to model the repulsion forces between sensor nodes. The Received Signal Strength (RSS) is transformed to the repulsion force for computing the next move distance and direction. The GF approach reduces the power consumption on communication overheads while the RD approach...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
