Energy-Efficient Node Placement in Linear Wireless Sensor Networks

Energy-efficient node placement is one of the main design issues for linear structure wireless sensor networks. Two types of node placement schemes studied in the paper are to maximize the network lifetime and to balance the network reload. For a given number of nodes, study the optimal spacing; for a given node spacing, study the optimal density of nodes. Simulation shows, two types of node placement schemes provide significant benefit over a commonly used uniform placement scheme, balance the network load and extend network lifetime.
