基于分簇和跨层的 MANET管理方案磁

摘要

Dynamic topology ,unstable link quality and heterogeneous node capacity in MANET made traditional net‐work management face enormous challenges .A three‐dimensional MANET management scheme based on clustering and lay‐er‐crossing combined with policy mechanisms is proposed .On the one hand ,using distributed management framework ,the scheme carries on clustering network management .It reduces the load on the network management node and enhances scal‐ability .On the other hand ,the scheme performs policies by layer‐crossing mechanism ,including cross‐layer state information sharing ,management function calls and policy adjustment management spending and makes the management process more flexible and efficient .This paper describes the management mechanism ,gives the system architecture and realization .The a‐nalysis shows that the scheme can improve efficiency ,flexibility and scalability of MANET management .%移动自组织网络（Mobile Ad hoc Networks ，MANET）拓扑动态变化、链路质量不稳定、节点能力异构，使传统的网络管理面临巨大挑战。提出一种结合策略机制的基于分簇和跨层的MANET立体式管理方案：一方面，采用分布式管理架构，对网络进行分簇管理，减轻网络管理节点的负载，增强可扩展性；另一方面，采用跨层机制执行策略，包括跨层状态信息共享、管理功能调用和策略调整，降低管理开销，使管理过程更加灵活高效。论文阐述了管理机制，给出了系统架构及实现。分析表明，该方案能够提高MANET管理的高效性、灵活性和可扩展性。
