We consider information retrieval in a wireless sensor network deployed to monitor a spatially correlated random filed. The measured data are sent to an access point through multi-hop transmissions. We address the joint design of sensor scheduling and information routing in each data collection to optimize a performance measure: network lifetime. We first formulate this problem as an integer programming based on the connected coverage in sensor networks. We then derive an upper bound for the network lifetime which provides a measure for the performance of suboptimal methods. After that, we propose a suboptimal method for node scheduling and data routing to maximize the network lifetime. In the proposed method, instead of treating them as two separated optimization problems, the scheduling and routing are integrated into a single algorithm: when scheduling the sensors for area coverage, we consider not only the network geometry but also the energy consumed for the data transmission; when designing the information routing, we consider the role of each sensor in the scheduling since some sensors have crucial importance on the area coverage and should be treated specially in the routing. We study the performance of the proposed method by comparing its result with the lifetime upper bound and the separated design methods. Numerical examples demonstrate the performance of the proposed method.
