Wireless Sensor Network Using Energy Efficient Ring Routing Protocol with Mobile Sink

In wireless sensor networks efficiency of energy is considered to be important role due to the limited battery capacity of sensor nodes. In existing system various hierarchical approaches have been experimented, in which each approach suffers from overhead, hotspot and flooding problem. In this paper we propose ring routing approach energy-efficient mobile sink routing protocol is introduced, which aims to minimize this overhead while preserving the advantages of mobile sinks. This ring routing approach is designed to support multiple mobile sink. The technique forms a ring of nodes from the available regular nodes. Ring is formed with the help of certain radius from the centre, nodes closer to the ring which is defined by the radius is formed. The location of the sink node is found through a ring node and is shared between all the ring nodes. Then the source node with the data forwards it to the sink through the anchor nodes. The proposed system achieves higher performance, lifetime and a smaller amount delay while compared with the existing system and this system prevents congestion, traffic between the nodes in case of large wireless sensor network.
