Abstract : 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.
