Hybrid Sink Repositioning Mechanism for Wireless Sensor Network
Durga Prasad Mishra, Ramesh Kumar · International Journal of Research in Advent Technology · 2019
Wireless sensor networks are a collection of tiny resource-constrained sensors deployed in a dense mode in a specific area to interact and accomplish specified tasks; major challenge that affects the lifetime of wireless sensor network is uneven, unpredictable energy consumption by nodes, in this paper, we have proposed a Hybrid mechanism for the deployment and repositioning of the Optimal Number of Sinks in wireless sensor network to increase the lifetime of sensor network and nodes.Sink deployment can provide an optimal solution but its not always feasible since it requires precise knowledge of the monitored area for the proper and optimal repositioning of the sink, in order to maintain the residual energy of wireless sensor nodes that improve lifetime and performance of the network.Proposed hybrid sink re-positioning technique will overcome issues specific to energy holes.In our case, we have used both stationary and moving sinks to gather the data from the sensor nodes.
