This work addresses the problem of designing the optimal network configuration for Wireless Sensor Network (WSNs). Specifically, given a surveying area our goal is to determine the parameters of network configuration such that some objectives are met. We begin by studying the configuration for a linear network and then extend our work to the two dimensional network area. For the linear network case we target two objectives: i) minimizing the overall energy consumption ii) and guarantying the node energy consumption fairness. Then we discuss the overall energy consumption minimization problem where the transmission energy takes only some given discrete values. Next, we study the network area configuration problem and show how the computation method given for the linear case can be extended to handle it. The solution method for these problems is based on dynamic programming algorithm which guarantees the optimality of the solution. This method has a low complexity compared to other methods proposed in the literature and it can be a great help for network designers thanks to its simplicity in implementation
