An improved routing scheme for wireless sensor networks with Hybrid Energy Storage System

In This paper we proposed an improved routing metrics for wireless sensor networks (WSNs) based on Hybrid Energy Storage System (HESS) which merges Super capacitor (SC) and a Rechargeable Battery (RB). The proposed routing scheme assigns different metrics considering not only residual energy, harvesting rates and expected path length of next hop, but also the potential of the future hops. Simulations results show that the proposed scheme can obtain a better delivery of data packets while maintain low latency in some situation.
