The Medium Access Control (MAC) protocol design for distributed wireless networks has been a topic of extensive research in the last years. The protocol design challenge relies on the infra-structureless nature of distributed wireless networks, which difficult the implementation of optimal throughput MAC schemes. However, interesting optimal-based MAC protocols have been proposed in the last years,...
This letter presents new results obtained with a novel MAC scheme designed to be reliable and maximize the throughput of a single-hop network. Contrarily to the IEEE 802.11 MAC scheme, all nodes adopt a common optimal contention window size for unicast and broadcast transmissions, which is based on a common view of the channel. In this way, the conditional collision probability is independent of the...
Current applications and services for ad hoc networks heavily rely in advertisements, which are transmitted using broadcast. In the current Medium Access Control (MAC) schemes, namely in IEEE 802.11, broadcast co-exists with unicast frames. While the transmission scheme used for unicast frames is considered reliable, the IEEE 802.11 does not offer any possibility of retransmission for broadcast frames...
