Abstract
Environmentally-powered wireless sensor networks (WSNs) exploit renewable energy sources to make the lifetime of sensor nodes theoretically unlimited. This perspective requires a paradigm shift in the design of energy-aware WSNs: Instead of maximizing the lifetime under given energy constraints, we need to maximize the workload that can be sustained by a given distribution of environmental power. This paper formulates the maximum energetically sustainable workload problem (MESW) and we shows that it can be cast into an instance of a modified max-flow problemFile in questo prodotto:
