An Approach to Place Sink Node in a Wireless Sensor Network (WSN)

In wireless sensor network (WSN), the data collected from the different sensor nodes are collectively forwarded to the special node called sink node. The placement of such sink nodes plays a vital role in reducing the propagation latency/delay and energy consumption of WSN. This paper addresses the problem of placing the minimum number of sink nodes in an un-weighted topology in such a way to maximize the link connecting different sensor nodes and proposes a heuristic approach to place the sink node in an appropriate location in the WSN.
