Ad Hoc网络协议栈通用要求研究

Ad Hoc网络是由一组带有无线收发装置的移动节点组成的一个多跳的临时性的自治系统。Ad Hoc网络与有线网络相比有很多特殊点，会导致传统的网络协议栈在Ad Hoc下不能有效使用。解决的办法是使Ad Hoc网络的网络协议栈满足比传统协议栈更高的要求：物理层要能实现分布式多点发起的同步，媒体访问控制（MAC）层要能管理多个分布站点随机的收发行为，网络层要能高效地管理分布式的路由协议，传输层要针对各种不同的业务进行优化。

General Requirements of Protocol Stack in Ad Hoc Networks

An Ad Hoc Network is a multi-hop, temporary and autonomous system composed by mobile nodes with wireless receiving and sending functions. Compared with wired networks, the Ad Hoc network has some unique characteristics that sometimes may cause the traditional network protocol stacks not to function well in Ad Hoc networks. The solution to this problem is to make the Ad Hoc protocol stack meet much higher requirements as follows, while compared with the traditional protocol stack. The physical layer is required to achieve synchronization initiated by distributed multiple nodes. The Media Access Control (MAC) layer should be able to manage the random receiving and sending at distributed multi-stations. The network layer should effectively manage the distributed routing protocols. The transport layer should have the capability to optimize the configuration for different services.
