Constrained Resource Optimization in Large-Scale Wireless Sensor Networks with Mobile Sinks

In this position paper we address key challenges in the deployment of wireless sensor networks (WSNs) with mobile sinks for large-scale, continuous monitoring. We propose a heterogeneous and hierarchical WSN architecture for such purpose. we also introduce several novel, constrained optimization problems related to this new paradigm of data gathering, which serve as the potential research topics in this area.
