Performance Analysis of Reliable Transmission on Multiple Paths and Single Path

Using multiple paths for achieving high capability has some obvious benefits. However, some multipath protocols may not get acceptable throughput if reliable transmission is guaranteed. For some case, the situation may even worse than using single path only. We propose a specific mechanism to analyze the potential problems which may lead to performance decrease in reliable multipath transmission. Topologies for multiple paths and single path are set up for evaluating our analytical methods. The results reveal some critical conditions and could be helpful in designing scheduling schemes for multipath transmission.
