Abstract

This paper proposes MiniMesh, an opportunistic transmission mechanism for theIEEE 802.15.3 medium access control (MAC) protocol; a key technology torealizing wireless personal area networks (WPANs). MiniMesh exploits thevarying channel conditions to devices in a WPAN, thereby enabling the senderand receiver of a flow to transmit at high data rates when the channelcondition is favorable. In addition, MiniMesh addresses the coverage problemthat limits peer-to-peer communications and is backward compatible with theIEEE 802.15.3 specification. We have implemented MiniMesh and the DS-UWBphysical layer that offers data rates ranging from 28 Mbps to 1 Gbps in the{\it ns-2} simulator. Our results show devices obtain at least a three foldincrease in throughput when only the piconet controller is serving as a relay;further increases are possible with additional relays. Moreover, a flowexperiences faster recovery from packet loss and is able to maintain a highthroughput even when channel conditions worsen.
