Abstract: | In this study, Random Contention-based Resource Allocation (RACOON) medium access control (MAC) protocol is proposed to support the quality of service (QoS) for multi-user mobile wireless
body area networks (WBANs). Different from existing QoS designs that focus on a single WBAN, a multiuser WBAN QoS should further
consider both inter-WBAN interference and inter-WBAN priorities. Similar problems have been studied in both overlapped wireless
local area networks (WLANs) and Bluetooth piconets that need QoS supports. However, these solutions are designed for non-medical
transmissions that do not consider any priority scheme for medical applications. Most importantly, these studies focus on
only static or low mobility networks. Network mobility of WBANs will introduce unnecessary inter-network collisions and energy
waste, which are not considered by these solutions. The proposed multiuser-QoS protocol, RACOON, simultaneously satisfies
the inter WBAN QoS requirements and overcomes the performance degradation caused by WBAN mobility. Simulation results verify
that RACOON provides better latency and energy control, as compared with WBAN QoS protocols without considering the inter-WBAN
requirements. |
