Additional sink placement strategy in wireless sensor network
S M Taiabul Haque, Rehana Tabassum · 2009
In Wireless Sensor Network, energy is the most critical resource constraint due to the limited battery power of each sensor node. Almost all applications of Wireless Sensor Network require the flow of sensed data from multiple sources to a sink. So, the optimal location of sink is an important topological consideration. In this work, we focus on the topological modification of Wireless Sensor Network after a certain period by adding new sink node. We find optimal location for placing new sink node in order to maximize the network lifetime.
