Abstract: In order to reduce overhead of dynamic source route protocol supporting mobile Ad Hoc networks, and improve the utilization ratio of wireless channel, it is crucial to use MAC address of 1 B to identify network node when route protocol is running. This paper researches how to dynamically assign a MAC address for node identified by IP address, and a dynamic assignment scheme based on prophet for MAC address is realized, which is conflict-free and low overhead. Practical application validates that the scheme for MAC address is applicable and reliable for mobile Ad Hoc network.

摘要： 减小动态源路由协议DSR的开销、提高无线信道的利用率的关键是在协议运行时，使用1 B的MAC地址对节点进行标识。该文研究了如何为特定IP地址标识的网络节点动态分配MAC地址，实现了一种基于预测的无冲突MAC地址动态分配方法，其中所引入的开销较低。实际应用表明，该分配方法具有较强的适用性、可靠性。
