Enabling opportunistic energy trading between overlapping energy harvesting wireless sensor networks
Enabling opportunistic energy trading between overlapping energy harvesting wireless sensor networks
Energy harvesting offers wireless sensor networks the possibility of indefinite operation. Their energy sources are typically uncontrollable and exhibit significant temporalspatial variation. Traditional approaches to managing their operation have been designed to adapt to these variances, but are inherently limited to only managing resources within the physical boundary of the network. Opportunistic Energy Trading (OET) was proposed to allow co-located WSNs to trade energy resources with each other, permitting energy management across network boundaries. In this paper, we extend this prior work by removing a number of simplifying assumptions. We consider the effect of varying degrees of overlap between neighbouring networks, mechanisms for monitoring and recording trades, and the modifications needed at higher layers of the protocol stack. To demonstrate our approach, we evaluate a case study where, during night, a solar-powered network ‘buys’ energy from a neighbouring battery-powered network to sustain operation.

Abstract
Energy harvesting offers wireless sensor networks the possibility of indefinite operation. Their energy sources are typically uncontrollable and exhibit significant temporalspatial variation. Traditional approaches to managing their operation have been designed to adapt to these variances, but are inherently limited to only managing resources within the physical boundary of the network. Opportunistic Energy Trading (OET) was proposed to allow co-located WSNs to trade energy resources with each other, permitting energy management across network boundaries. In this paper, we extend this prior work by removing a number of simplifying assumptions. We consider the effect of varying degrees of overlap between neighbouring networks, mechanisms for monitoring and recording trades, and the modifications needed at higher layers of the protocol stack. To demonstrate our approach, we evaluate a case study where, during night, a solar-powered network ‘buys’ energy from a neighbouring battery-powered network to sustain operation.
