Dead End Free Topology Maintainance Protocol For Sinktrail
Wireless sensor network uses a sensor to monitor and record physical condition of environment and organised the
data at central location. There is sufficient flexibility in the movement of mobile sinks to dynamically adapt to various
terrestrial changes, without requirement of GPS devices or predefined landmark. SinkTrail established a logical coordinate
system for routing and forwarding data packets, making it suitable for diverse application scenario. SinkTrail protocol suffer
from dead end while routing or forwarding data packets. Our proposal reduces the control overhead and find out alternative
neighbourhood node if dead end situation occur in SinkTrail. It also find the shortest routing path using dead end free
topology.The dead end phenomenon (also known as the local maximum problem) when performing geographic forwarding
in wireless sensor network add some overheads forward the packet to the alternative route.
