The Beauty of the Commons: Optimal Load Sharing by Base Station Hopping in Wireless Sensor Networks

Martin Vetterli, Patrick Thiran, Guillermo Barrenetxea Kobas, François Ingelrest, Runwei Zhang

In wireless sensor networks (WSNs), the base station (BS) is a critical sensor node whose failure causes severe data losses. Deploying multiple fixed BSs improves the robustness, yet requires all BSs to be installed with large batteries and large energy-ha ...
