Clustering is one of the energy-efficient solutions for the WSN in the static sink environment. The data is sensed by regular nodes and sent to the Cluster Head (CH). By deleting redundant packets, the CH collects and aggregates the data. Finally CH sends data to the sink node using single or multi-hop communication. The selection of CH depends on parameter like residual energy, distance form base station, density etc. In multi-hop network the sensed data from the remote nodes is transferred to sink through intermediate nodes. Thus the energy depletion is faster for nodes which are closer to the sink. This non uniform energy depletion reduces the network lifetime and disconnect sink node from other nodes. To overcome such condition Mobile Sink (MS) concept has been introduced. MS is used to collect data from nodes by traveling in the network and it is used to increase the network lifetime and delay constraint.
