TCP performance over cluster-label-based routing protocol for mobile ad hoc networks

초록

The performance of a TCP protocol on MANETs has been studied in a numerous researches. It has been shown that performance of TCP on MANET is poor and that it is caused by two groups of reasons: one inherited from wireless networks and one caused by nodes mobility. One reason of TCP degradation is inability to distinguish between packet losses due to congestion from those caused by nodes mobility and as consequence broken routes. This paper presents the Cluster-Label-based Routing protocol that is an attempt to compensate source of TCP problems on MANETs - multi-hop mobile environment. By utilizing Cluster-Label-based mechanism for Backbone the CLR is able to concentrate on detection and compensation of movement of a destination node. The proposed protocol provides better goodput and delay performance than standardized protocols especially in cases of large network size and/or high mobility rate.
