Abstract

In this paper Cwe propose a new MAC protocol in presence of multiple wireless Body Area Network (BANs) which can for reduce inter-WBAN interference and improve overall performance of all BANs. A BAN system consists of a coordinator and some sensor nodes. When coverages of multiple BANs are overlapped, some packets transmitted from sensor nodes of different BANs cause interference. Although an international standard for wireless medical BAN, i.e. IEEE802.15.6 can reduce intra-WBAN interference within a single BAN, inter-WBAN interference caused by coexistence of multiple BANs can not reduce effectively. Therefore, this paper proposes such a new MAC protocols method that coordinators of overlapped BANs can negotiate among coordinators of BANs. In addition, to enable priority control which is a feature of the standard, we propose a method that changes parameters of the proposed method according to priority of packets. Throughput and delay time of the proposed scheme are illustrated by simulation, in which it is convinced that the proposed scheme can improve overall performance such as throughput and delay considering efficiency of priority control.
