The WiMedia UWB MAC protocol is currently preferred among the wireless standards since it does not require the global coordinator in the ad-hoc network, i.e., a fully distributed beaconing network, and also it supports Quality of Service (QoS) unlike other WPAN protocols. Due to the changes of radio propagation environments, mobile nodes, or other effects, devices using two or more unaligned BPSTs may coexist in the range. This causes synchronization problem and is solved by merging two networks in the WiMedia. However, some applications such as HD-level video distribution in a subway train need a method of merging three or more beacon groups. In this long serial merged beacon group, multi-hop transmission should be realized. In this environment, we should consider several problems such as addressing, the number of available beacon slots, and spatial reuse of beacon slot, multi-hop routing algorithm. In this paper, we present requirements of multi-hop routing in the WiMedia network and analyze the existing routing protocols.
