Efficient broadcasting for multi-radio mesh networks

This book addresses the problem of efficient §broadcast in a multi-radio multi-channel multi-rate§wireless mesh network (MR2-MC WMN). In such networks,§nodes are equipped with multiple radio network§interface cards, each tuned to an orthogonal channel,§that can dynamically adjust transmission rate by§choosing a modulation scheme appropriate for the§channel conditions. The specific problem this book§addresses is called the§`minimum-latency-broadcasting'' (MLB) problem in which§the goal is to minimize broadcast latency , defined§as the maximum delay between a packet s network-wide§broadcast at the source and its eventual reception at§all network nodes. Many broadcast-based applications§of WMNs have strict latency requirements: e.g., IPTV,§audio conferencing, video-feeds, multi-player games;§these and other latency-sensitive WMN applications§can benefit from the algorithms proposed in this§book. Important insights are also presented for§designers of routing protocols for multi-radio§multi-rate wireless networks.
