摘要

本文研究了利用802.11 DCF穿越一跳自组织网络的单播和广播流量的相对性能。建立了一个扩展的马尔可夫模型,并通过计算机仿真进行了验证,成功地预测了单播和广播在各种混合流量场景下各自的性能。在繁重的网络流量条件下,两种流量类别的性能之间出现了显著的差异——特别是,当网络变得饱和时,单播流量实际上比广播具有更高的优先级。因此,网络被单播帧所主导,导致广播帧的传输速率很低。

Characterising the Interactions Between Unicast and Broadcast in IEEE 802.11 Ad Hoc Networks
This paper investigates the relative performance of unicast and broadcast traffic traversing a one-hop ad hoc network utilising the 802.11 DCF. An extended Markov model has been developed and validated through computer simulation, which successfully predicts the respective performance of unicast and broadcast in a variety of mixed traffic scenarios. Under heavy network traffic conditions, a significant divergence is seen to develop between the performance of the two traffic classes - in particular, when network becomes saturated, unicast traffic is effectively given higher precedence over broadcast. As a result, the network becomes dominated by unicast frames, leading to poor rates of broadcast frame delivery.
