Abstract

In mobile ad hoc networks (MANET) with contention-based MAC, the nodes along a path of transmission contend for access the medium in a distributed manner, this leads to intra-flow contention that cause degradation in the network performance. The precision for determining the intra-flow contention helps any contention-based admission control to make correct decisions to admit or reject any new flows, and in turn improves the performance of the network. However, the calculation of the intra-flow contention is challenging, because the nodes only know their neighbors that are located within the transmission range, but do not aware about those are located between the edge of the carrier sense range and the transmission range, or those are located within interference range of the receiver. This paper analysis the intra-flow contention and evaluates the existing methods in the literature for calculating the contention count. The analysis shows that, the current methods still have limitation in term of the covered area for calculating the intra-flow contention, they also have considerable overhead and delay that cause impact on the throughput in MANETs.
