Sink Trail Protocol Extention with Dead End Free Topology Used in WSN
International Journal of Science and Research (IJSR) · 2015
Wireless sensor network (WSN) uses a sensor node to observer and stored environmental physical condition and organised the data at central location.There are to much divercity in the movement of mobile sinks due to continueous changes in the terrestrial, without using GPS devices or predefined landmark.SinkTrail sends data packets by making a logical coordinate system using routing and forwardings, so that it can be used in wrost application scenario.A local maximum problem that is dead end while routing or forwarding data packetsis the primary drawback of sinktrail .In order to overcome from this primary drawback we extend sinkTrail with a Dead End Free Topology (DEFT) in our proposed system.Such system can have the capability and efficiency to deal with the dead end occurred in the sink trail protocol.This type of system also provide facility for do not occurred dead end situation and also find shortest routing path using dead end free topology.
