A Study of the Optimal Packet Length in Mobile Ad Hoc Networks
无线Ad Hoc网络中最佳分组长度问题的研究

The effect of different packet length to network performance of mobile Ad Hoc network when transmitting CBR traffic is studied and the corresponding optimal packet length is given. Extensive simulations are made on a scenario where nodes move randomly with DSR routing protocol used. The simulation results show that there exists an optimal packet length which can optimizes the network performance when the number of CBR connections is given. The network performance becames worse rapidly when the packet length decreases from the optimal value gradually. On the other hand,the network performance becames worse slowly when the packet length increases from the optimal value gradually.
