Continuous Neighbor Discovery in Wireless Sensor Network

In sensor network the node connectivity is to be changes of disruption in wireless communication, transmission power changes or loss of synchronization between neighbour nodes. Hence a sensor is aware of its immediate neighbour it must continuously maintain of its view. It’s called continuous neighbour discovery. In this paper it differentiates between neighbour discovery during sensor network initialization and continuous neighbour discovery. It’s used to reduce the power consumption without increasing the time required to detect hidden sensors. In sensor network, the node is to detect their immediate neighbor which they direct communication that is used to establish routes to the gateway.
