摘要: In this paper, we investigate the energy efficiency of an incremental relay based cooperative communication scheme in wireless body area networks WBANs. We derive analytical expressions for direct and schemes taking into account effect packet error rate. The following scenarios specific to a WBAN are considered: i in-body between implant sensor node gateway, ii on-body surface gateway with line-of-sight LOS non-LOS channels. results reveal threshold behavior that separates regions where transmission is better from cooperation more useful terms efficiency. It observed that, compared communication, improves significantly. Further, extends source-to-destination hop length over, which efficient can be achieved as communication. also observe both well prone channels, optimal size exists result maximum Copyright © 2013 John Wiley & Sons, Ltd.
