Abstract

In the coming age of the Internet of Things with the presence of huge number of smart mobile devices around, instead of sending packets directly to the access point/gateway, the system will be highly energy efficient, if nodes forward packets via nearest neighbors in multi-hop paths. To motivate the intermediate nodes to relay packets, this letter proposes, an energy incentive model for sharing wide band cognitive spectrum to compensate the energy loss in nodes due to packet relaying. Analysis for linear networks with its generalization for random networks and the simulation studies show that the proposed scheme not only saves energy significantly, but also maintains energy balance independent of the relay load with a marginal increase in scanning overhead.
