Dynamic Model for Efficient Data Collection in Wireless Sensor Networks with Mobile Sink
Deepak Puthal, Bibhudatta Sahoo, Suraj Kumar Sharma · 2012
WSN is a multi-hop network which depends on the intermediate node to relay the data so the energy of the nodes near to the sink exhausted very quickly, as a result network gets disconnected. To over the problem and to prolong the lifetime of the network we proposed Mobile Sink Wireless Sensor Network (MSWSN) model which uses a mobile sink to collect the data. We also proposed a mobility model to the sink to move in the network and cover the whole network area. Further we compare the simulation results with existing protocols and find that the proposed model gives better results in terms of throughput, residual energy and lifetime of the networks.
