Abstract

Wireless multihop networks, built with tactical radios, have limited bandwidth; yet often need to support bandwidth-intensive 1-to-many and many-to-many communications. Efficient routing proposals for wireless broadcasting have been suggested in the literature, and more recently the use of network coding to efficiently support such communication patterns. This paper explores the use of efficient broadcasting protocols with and without the use of network coding. Through extensive simulation studies and comparisons of protocol and coding options, the performance gains and the relative tradeoffs of different approaches are unveiled for practical tactical networking scenarios.
