In this paper, methods for constructing two dimensional nearest neighbour balanced (NNB) designs are considered. The methods given by Afsarinejad and Seeger (1988) are extended to give a new family of nearest neighbour balanced designs. Both nearest neighbour balanced designs with and without borders are constructed. A method of construction of a class of partial nearest neighbour balanced (PNN...

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 ...
