Hybrid Energy Storage-Aware Routing for Saving Battery Cycle Life


In hybrid energy storage system (HESS) has both a supercapacitor (SC) and a rechargeable battery (RB). Today, HESSs are used in some radios, with the SC playing the role of the “surge protector” for the RB; however, the RBs are still accessed for every transmission. Existing harvesting-aware routing protocols do nothing to avoid exhausting the short cycle life of RBs.  We propose an HESS-aware routing protocol that utilizes the SC energy exclusively whenever possible, and when it is not possible, chooses the path that maximizes RB cycle life.
