Analysis of Mobile Sink Based Routing Protocols in Wireless Sensor Networks

Abstract

In Wireless Sensor Network (WSN), the nodes are deployed densely all over the network region to sense the surroundings and transmit data to the Sink Node (SN). Basically, sensor networks are used for the applications like military surveillance, industrial monitoring, health or medical sensing, building and home automation, etc. Sensor nodes are responsible for sensing as well as processing the gathered data and transmit it to the SN. Direct communication between the SN and to the sensor nodes consumes a high amount of energy and the nodes tend to dissipate their energy faster. Hence, implementing mobility on the SN, to move through the network region for the data collection process, gives better result in terms of network lifetime. In this paper, Wireless Sensor Network’s different existing Mobile Sink (MS) based routing protocols are studied. The protocols considered here are designed to conserve the energy of the network implementing mobility to the Sink Node (s). We studied the mobility patterns of the Sink Node (s) and comparisons have been made on their results and the methodologies followed.
