Performance evaluation of multi-path and single-path routing protocols for mobile ad-hoc networks

There is an ambiguous opinion in the literature on whether multi-path routing offers significant merit in terms of a networkpsilas performance. The one camp supports the belief that multi-path routing is indeed advantageous compared to single-path counterparts and the other contends that the improvement is not significant, if at all. For the performance evaluation of the two counterparts, Dynamic Source Routing (DSR) protocol, is compared against a modified version of DSR which exploits multiple node disjoint routes. The comparison of the two routing schemes, is carried out using the Network Simulator ns-2, and the comparison is performed for static and mobile scenarios. The performance is quantified and it is shown that the proposed routing scheme outperforms the unipath counterpart.
