Abstract
A wireless sensor network (WSN) is comprised of small, low powered self-organizing sensor nodes, densely deployed in the area to be monitored. WSN is a high scalable network deployed over a large area of interest for various applications. Since all sensor nodes are energy constrained, it becomes all more important to reduce the draining of energy of those nodes closer to the sink, simply because they are in the path of data propagation towards the sink. Further, the sink’s neighboring nodes would drain their energy faster leading to disconnected network. With a mobile sink, the nodes around the sink always changes, thus balancing the energy consumption in the network and improving the network lifetime. We evaluate the effect on Network Lifetime in wireless sensor networks due to the movement of sink in random walk and predefined path.
