| Abstract: | Based on efficient scheduling and adapting sensing ranges which are the two important methods for maximizing wireless sensor network lifetime, we study the maximum set covers problem with adjustable sensing ranges (MSC-ASR), propose a mixed integer programming model, and demonstrate that MSC-ASR is a NPC problem. For solving MSC-ASR, we present two methods: centralized algorithm and distributed algorithm. Simulations show that the algorithms are effiective. |
