Cooperative energy harvesting-adaptive MAC protocol for WBANs.

Esteves V, Antonopoulos A, Kartsakli E, Puig-Vidal M, Miribel-Català P, Verikoukis C - Sensors (Basel) (2015)

Bottom Line: In this paper, we introduce a cooperative medium access control (MAC) protocol, named cooperative energy harvesting (CEH)-MAC, that adapts its operation to the energy harvesting (EH) conditions in wireless body area networks (WBANs).In particular, the proposed protocol exploits the EH information in order to set an idle time that allows the relay nodes to charge their batteries and complete the cooperation phase successfully.Extensive simulations have shown that CEH-MAC significantly improves the network performance in terms of throughput, delay and energy efficiency compared to the cooperative operation of the baseline IEEE 802.15.6 standard.

Mentions: We consider a WBAN consisting of a source (S), a destination/hub (H) and n relay nodes (Figure 1). We assume that a direct link is established between the source and the hub, with a packet error rate (PER) denoted by PERS−H. However, whenever the direct transmission fails, the relays that have overheard the transmitted data enter a contention phase in order to attempt new retransmissions. Regarding the cooperative links, we assume a symmetric topology with identical channel errors in the links between the source and the relays (denoted by PERS−R) and in the links between the relays and the destination (denoted by PERR−H).
