【摘要】 基于时分多址(TDMA)的媒体接入控制(MAC)协议能够提供很好的无线资源利用率,特别是在高负载的环境下。提出的适于AdHoc的MAC协议实现了节点间的自我同步、无冲突传输并由接收方发起。协议中,接收方作为本地基站可以在一个时隙上管理一个或多个传输。理论分析和仿真表明该协议与IEEE802.11相比提高了系统吞吐量并降低了端-端延迟。更多还原

【Abstract】 Time division multiple access(TDMA) based media access control(MAC) protocol provide a good utilization of the radio resources,especially at high input loads environment.The nodes self-synchronization,collision-free and receiver-oriented are realized in this proposed MAC protocol for Ad Hoc networks.In this protocol,receivers act as local base stations and can manage one or more communications on a single slot.A theoretical analysis and simulations show that this protocol improves throughputs and decreases end-to-end delay as compared with IEEE 802.11.更多还原
