Energy-efficient topology control for wireless sensor networks using online battery monitoring

[摘要] This paper presents a first approach towards cooperative energy managementin wireless sensor networks using online battery monitoring. Using astandard platform for wireless sensor networks, a simple concept formeasuring the battery voltage on the mote with little additional hardware isshown. This is used for modelling of the battery discharge behaviour ofLi-Ion batteries and deriving the remaining lifetime under givenenvironmental conditions. As an application example this model can beincorporated into a topology control scheme for optimized network lifetimeunder variable environmental conditions.
