Tactical adhoc nets is a sudden data services primarily packet radio network,traffic has actually had a kind of self-similar characteristics,in traditional retreats algorithm easily cause congestion problems node cache queue,and proposes an improved retreats algorithm is applied to tactical network traffic.The improved algorithm into the appropriate competition for node to channel that the coefficient of the current network access may,according to the state of emergency,and according to reasonable dispatch network state,and conflict node on competition conditions,and used respectively to linear,window size of linear and multiple down heavy growth means such as dynamic adjustment,improve the network performance.Simulation results show that the modified retreats algorithm has better performance and network retreats algorithm reduce the network channel access conflict probability.The tactics of adhoc network traffic resources disposition has very big value.
