摘要

在深入剖析多速率机制导致不公平性根源的基础上

提出了基于传输速率的数据分组长度调整(TRPSA)策略

该策略保证了传输速率不同的节点能公平地占用无线信道。理论证明和仿真验证了该策略能有效实现多速率多节点情况下的公平性

显著提高网络性能。该策略只需对IEEE 802.11做细小修改

易于在实际网络中实现和推广。

Abstract

After deeply analyzing the reasons of the unfairness in the multi-rate mechanism

the new strategy

transmission rate-based packet size adjustment（TRPSA） was provided.This strategy guaranteed that each node with different transmit rate could access the wireless channel fairly.The theoretic proof and the extensive simulation validation show that the proposed strategy can achieve the efficient fairness and improve the network performance under the multi-rate multi-node situation.The proposed strategy slightly modifies IEEE 802.11.Thus

it is easy to be implemented and widely applied in the practical network.
