In this work, by bridging the IEEE 802.15.6-based WBANs and the IEEE 802.11e EDCA-based WLAN we develop a wireless healthcare network. We assign 8 WBAN User Priorities (UPs) to the WBAN nodes. By mapping the UPs into 4 WLAN Access Categories (ACs) we convey the medical data to the WLAN access point. We investigate the network performance under varying priority differentiation and number of nodes in...
Since the signal transmission in WBANs takes place around or in the human body, the channel fading significantly affects the error performance of the networks. In this paper, we investigate MAC performance of an IEEE 802.15.6-based WBAN operating over a Rician-faded channel. We deploy Bit Error Rate (BER) as a function of channel quality, diversity order, and Signal to Noise Ratio (SNR) values for...
A Wireless Body Area Network (WBAN) aims to provide real-time and ubiquitous body monitoring to perform autonomous early prediction, diagnostic, and tracking the response of the body to treatments. IEEE 802.15.6 is a communication standard for WBANs which pervasively and continuously monitor the human body. In this paper, we develop an analytical model for performance evaluation of the IEEE 802.15...
In this paper we investigate the ratio of dwelling time in control channel (CCH) and service channel (SCH) for single channel devices deploying WAVE (Wireless Access in Vehicular Environments) protocols. Based on analytical model for both channels and four traffic types we present tradeoffs in channel performance when CCH/SCH duty cycle is changing. Our results show that, when video traffic is absent,...
