Description

Sink mobility has been proven to be an effective way for minimizing delay in data delivery and mitigating the hot spot problem in wireless sensor networks (WSNs). However, there is an impact of the path selection for the mobile sink on the data delivery delay. Hence selection of optimal number of halting positions called rendezvous points (RPs) and their locations are challenging in WSNs. In this proposed system we implement an algorithm for the selection of MS with the consideration of the rendezvous points that is the meeting points of the cluster nodes. In that proposed system, we perform the operation for consider the delay bound path formation of the MS. The intention behind using a Mobile sink (MS) is to decrease the transmission cost and unbalanced energy consumption among the SNs. cost and unbalanced energy consumption among the SNs. In large -size WSNs, to make sure that the data are conveyed to the base station within in delay limit, the MS could not travel nearby each SN and gather data sequentially, hence only SNs that are deployed near the MS’s path can directly send data to the MS and the remaining nodes convey their data to the MS in a multi-hop manner. The two RkM and DBRkM will resolve the mobile hotspot problems. And the performance of the system is evaluated by the simulation of the nodes in the network and the efficient data gathering of the mobile sink in the network. And the performance results shows that the proposed system gives the better results than the existing system.
