Abstract EN
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 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 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.
