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.

Klappentext
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.
