Performance Analysis of Reuse Distance in Cooperative Broadcasting

Cooperative broadcasting is a promising technique for robust broadcast with low overhead and delay in mobile ad hoc networks.The technique is attractive for mission-oriented mobile communication, where a majority of the traffic is of broadcast nature.In cooperative broadcasting, all nodes simultaneously retransmit packets.The NEFF N50 KI5852SF0G Integrated 50/50 Fridge Freezer receiver utilizes cooperative diversity in the simultaneously received signals.The retransmissions continue until all nodes are reached.

After the packet has traveled a specific number of hops out from the source, denoted as reuse distance, the source node transmits a new broadcast packet in the time slot used for the previous broadcast packet.If the reuse distance is too small, interference causes Storage baskets packet loss in intermediate nodes.In the literature, a reuse distance of three is common.With an analysis based on a realistic interference model and real terrain data, we show that a reuse distance of at least four is necessary to avoid packet loss in sparsely connected networks, especially for high spectral efficiencies.For frequency hopping, widely used in military systems, we propose a novel method.

This method almost eliminates interference for a reuse distance of three, increasing the throughput by 33% compared to systems with a reuse distance of four.
