Abstract:
Performance on multi-hop networks suffers from limited throughput capacity and poor scalability problems as the network size or density increases (Gupta and Kumar, 2000). One way to alleviate these problems is to equip each node with multiple radios. As hardware cost drops, this approach becomes more and more appealing and feasible. By tuning radios into non-interfering channels, the wireless spectrum can be more efficiently utilized, thus enhancing the whole network performance. This work extensively evaluates Dynamic Source Routing Protocol(DSR) (Johnson and Maltz, 1996) for multi-radio multi-hop networks. Through simulations, DSR with multi-radio extensions exhibits an overall performance improvement for throughput, packet delivery rate and latency.
