Performance analysis of cross-layer approach about error control scheme for WBANs

Abstract

In this paper, we analyze performance of our error control scheme in a cross-layer design for wireless body area networks (WBANs). As in our previous work, we have proposed an optimal QoS control scheme that employs a multiplexing layer for priority scheduling and a decomposable error control coding scheme for WBANs. However, a cross-layer approach has not been considered yet. In this paper, we utilize a crosslayer approach at physical (PHY) and medium access control (MAC) layers and analyze performance of our proposed error control scheme and the standard scheme. Numerical results show that our proposed scheme has better performances than the standard scheme. For instance, we show that the proposed system obtains over 6dB gain than the standard about the probability of unsuccessful transmission. Additionally, the case utilizing a schedule access protocol has better performances than a random access protocol.
