In this paper we study thetarget Q-coverage(TQC) problem where each target needs to be covered by different numbers of sensors. We try to find a collection ofQ-covsetswhich satisfy the coverage quality requirement to maximize the network lifetime. We first prove that the problem is NP-Hard. Then we design a greedy algorithm to efficiently compute theQ-covsets. Finally, simulation results are presented to verify our approach.
