| Abstract: |
Broadcast transmission mode in ad hoc networks is critical to support probing and routing procedures. In this paper, we present a novel topology-transparent protocol for broadcasting, which guarantees a minimum average throughput per neighbour. Throughput and delay gains are the result of a physical-MAC cross-layer design based on retransmission combining. Coherent detection and separation of contending nodes is possible through training sequences which are selected at random from a reduced set. Guidelines for the design of this set are derived for a low impact on the network performance and receiver complexity. |
