Abstract 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.
