On renewable sensor networks with wireless energy transfer [PDF]
2011 Proceedings IEEE INFOCOM, 2011 Traditional wireless sensor networks are constrained by limited battery energy. Thus, finite network lifetime is widely regarded as a fundamental performance bottleneck. Recent breakthrough in the area of wireless energy transfer offers the potential of removing such performance bottleneck, i.e., allowing a sensor network remain operational forever. In
