In wireless mobile ad-hoc networks, data packets have tobe relayed hop by hop from a given source node to a destinationnode. This means that some or all of the mobile nodesmust accept to forward information for the benefit of othernodes. It has been shown in [10] that this ability of forwardingpackets leads to a new unfairness problem in wirelessad-hoc networks, where a node which is forwardingother nodes' packets gets less bandwidth, for its own use,than a node which is not participating to the routing service.The proposed RAMAC scheme in [10], has showed allits effectiveness to cope with this unfairness problem. However,an extra bandwidth is sometimes allowed to the routingnode's own traffic comparing to other non routing nodes'own traffics, and the routing node's routed traffic gets muchless bandwidth. This is explained by the fact that at the upperlayer (for instance the IP layer) does not differentiatebetween the routing and the own traffics, and that the multiplicativefactor used to compute the new contention windowis too aggressive. In this paper, an enhanced RAMACscheme is proposed, by taking into account the differentiationon top of the MAC layer, between the and routed traffics within a routing node, and by smoothing the multiplicativefactor used to compute the new contention window. Thesimulation results obtained showed a good improvement ofthe original RAMAC scheme, leading to better approximateequal bandwidth share among all the mobile nodes in thewireless ad-hoc network.
