Abstract Algorithms for scheduling TDMA transmissions in multi-hop networks usually determine the smallest length conflict-free assignment of slots in which each link or node is a...
An ad-hoc network comprises mobile nodes that cooperate with each other using wireless connections to route both data and control packets within the network. As the low transmissi...
