Impact of limiting number of links on lifetime of wireless sensor network
Wang Zhichao · Computer Engineering and Applications Journal · 2012
For the energy constrains wireless sensor nodes,it is an important task to optimize the lifetime of Wire-less Sensor Network(WSN).By means of an Mixed Binary Linear Programming(MBLP)framework,it investigates the impact of limiting the number of incoming/outgoing links on the WSN lifetime.The MBLP is used for maximizing WSN lifetime and gives the corresponding constraints.Then,by the linear network topology,the impact of node number and area per node on the network lifetime of WSNs are analyzed.Performance analysis shows that the decrease in WSN lifetime is less than 1.0%if the limits on the number of incoming and outgoing links are not lower than three.Thus further proves that splitting the flows into three parts is good enough to balance the energy consumption among the sensor nodes.
