SinkTrail Protocol with a Dead End Free Topology Used In WSN

Now a day WSNs are widely used in many reasons such as monitoring of various conditions related to the environment, precious species and monitoring the infrastructure, process control in many automation company etc. As we know that all such WSN are built around sensor nodes. Providing security to this node as well as energy consumption of this node are very challenging. There are lots of flexibility in the movement of mobile sinks to dynamically achieve to various terrestrial changes, without using GPS devices or predefined landmark. SinkTrail creates a logical coordinate system for routing and forwarding data packets, so that it can be used in diverse application scenario. SinkTrail protocol has a major disadvantage of dead end while routing or forwarding data packets. In Our proposed system we reduces the control overhead and find an alternate neighbourhood node if dead end occur in SinkTrail. Here we also find the shortest routing path using dead end free topology.
