Network lifetime maximization with guaranteed coverage is an important issue in wireless sensor networks. Based on our recently proposed confident information coverage (CIC) model, this paper studies the multi-modal confident information coverage (M2CIC) problem. Assuming that each node is equipped with different types of sensors, the objective is to schedule the multi-modal sensors’ activity, such...
In this paper, based on our proposed confident information coverage model [1], we address the multi-modal confident information coverage (M2CIC) problem, with the goal of maximizing the network lifetime of a wireless sensor network. We model the M2CIC problem as a multi-modal set cover problem (M2SC), which is a NP-complete problem. For solving the M2SC problem, we design two energy-efficient greedy...
