【摘要】 MANET(Mobile Ad Hoc Network)是由一组无线移动主机组成的一个没有任何建立好的基础设施或集中管理设备的临时网络。网络拓扑易变、带宽、能源有限是Ad Hoc移动网络的主要特点。重点介绍了Ad hoc网络的组网关键技术——路由协议,并对现在的具有代表性的协议性能进行了比较,研究了在不同环境下的各自路由协议仿真实验所体现出来的性能差别,对Ad hoc的组网具有指导意义。更多还原

【Abstract】 Mobile ad hoc networks (MANETs) are collections of wireless mobile nodes, constructed dynamically without the use of any existing network infrastructure or centralized administration. Due to the limited transmission range of wireless network interfaces, multiple hops may be needed for one node to exchange data with another one across the network. MANETs are characterized by limited power resource, high mobility and limited bandwidth. Routing in MANETs is very important technology. Routing in ad hoc networks is analyzed and compared, in terms of delay, traffic distribution and connection throughput. The results reveal that in comparison with AODV, DSR and CBRP mechanism create more delay and overhead but provides better performance in connection throughput.更多还原
