摘要

自组织网络由MAC、路由协议和物理环境组成。本文研究了自组网环境下最大传输单元(MTU)的最佳大小。对于性能指标，定义“吞吐率”。吞吐量是整个系统接收的数据包数量与发送的数据包数量之比。随着节点移动的增加，路由失败造成的损失也会增加。在没有误码率的情况下，250字节到750字节之间的mtu具有更好的吞吐率。在10/sup -4/ BER中，最大传输速率为500字节。在无误码率条件下，AODV的性能略好于DSR。

Optimum UDP packet sizes in ad hoc networks

Ad hoc networks are comprised of MAC, routing protocols and physical environments. In this paper, optimum MTU (maximum transmission unit) sizes are studied in the ad hoc network environment. For performance index, "throughput rate" is defined. The throughput rate is a ratio between the number of packets received and packets sent through the overall systems. As node movements increase, losses increase because of routing route failure. MTUs between 250 bytes and 750 bytes have better throughput rates under no BER circumstances. 500 bytes MTU has the best throughput rate in 10/sup -4/ BER. AODV has a slightly better performance than DSR under no BER conditions.
