....asymmetry and derive analytical expressions for throughput in terms of packet loss probability and the normalized asymmetry ratio under certain ideal assumptions. They also propose the use of a drop from front strategy for dropping acknowledgments at the bandwidth constrained reverse link. In [15], the authors demonstrate how bidirectional traffic over asymmetric links leads to ack compression, and consequently, degraded performance. They investigate a backpressure mechanism to limit data flow in the reverse direction, but conclude that this alone is not enough for good performance. There ....
....network we consider in this study is that the former has a much larger bandwidth delay product, which could be the dominating factor in performance. Finally, some basic performance measurements of Metricom s Ricochet packet radio network are presented in [7] While the results and analysis in [15] and [18] are very useful, the set of problems is far from being understood or solved. In addition to proposing and evaluating other schemes to alleviate the adverse effects of bandwidth asymmetry, we also characterize other types of asymmetry that occur in wide area wireless networks. We evaluate ....

....acks) flowing in each direction. They conclude that a large value of this ratio can have an adverse impact on TCP performance. To alleviate the performance problems, they suggest drop from front packet discard policy and weighted round robin scheduling at the upstream router. Kalampoukas et al. [58] studied the impact of two way (i.e. bidirectional) TCP traffic over asymmetric access networks. They show that downstream throughput could suffer because TCP traffic in the upstream direction may cause excessive queueing of acks at the upstream router. They propose a backpressure mechanism to ....

....a much larger bandwidth delay product, which could be the dominating factor in performance. Finally, some basic performance measurements of Metricom s Ricochet packet radio network are presented in [5] such as oneway transmission delays of unidirectional traffic. While the results and analysis in [13] and [16] are very useful, the set of problems is far from being understood or solved. In addition to proposing and evaluating other schemes to alleviate the adverse effects of bandwidth asymmetry, we also characterize other types of asymmetry that occur in wide area wireless networks.
