无线网移动通信数据传输性能优化设计

Wireless Mobile Communication Data Transmission Performance Optimization Design

针对无线网移动通信数据传输性能进行优化,可以有效提高无线网移动通信效率。由于无线网移动通信数据容易受到通信距离的影响,使得通信数据特征存在动态波动性,传统的数据传输性能主要通过动态源路由(DSR)算法进行优化,优化后分组开销大,出现时延,导致通信效率差,误差大的问题。提出一种分组头压缩的改进型DSR算法(PHC-DSR)。通过散列操作和取模运算,将数据分组头中的完整路径信息压缩成一个较低位数的路径摘要,降低路由发现阶段的路由应答(RREP)数据包长度和数据包传输阶段所发送的控制信息的大小。仿真结果表明,改进的动态源路由算法可以有效的提高无线网移动通信数据传输的性能,增加通信数据传输效率。

In this paper, we propose an algorithm of packet head contraction DSR （ PHC - DSR）. Full path data packet head was compressed to a lower - order digit path abstract via hash handle and modular arithmetic. Packet length of route response data in route discovery stage and control information size in data packet transfer stage were reduced. Simulation results show that the modified PHC - DSR can enhance wireless networks mobile communication data transmission performance and increase its efficiency.
