一种k跳分簇Ad Hoc网络协作框架

基于k跳簇的特殊结构，提出了一种k跳分簇Ad Hoc网络协作框架。簇首根据启发式规则选择合适的簇间协作网关节点，自适应地管理簇间协作关系。相部的协作“网关节点”与簇首协作，管理簇内节点、网关节点的移动。当簇首发生移动时，选择合适的节点完成簇首信息的交接。移动代理在簇首节点间漫游，实现全网络协作，扩大k跳簇首的知识范围。仿真结果表明，协作框架能够以较低的控制负载高效地管理k跳分簇Ad Hoc网络中的移动节点，并提供网络级的协作。

Cooperation Framework for k-hop Clustered Ad Hoc Networks

Based on the special structure of k-hop cluster, presented a kind of cooperation framework for k-hop clustered Ad Hoc networks. Cluster heads utilize heuristic rules to select cooperative gateway nodes and set up adaptive intercluster cooperation. Neighboring gateway nodes cooperate with cluster-heads to manage the mobile cluster members and gateway nodes. When cluster head is moving, it transmits information to an optimal replacing cluster head selected by cluster head itself. Mobil agents roam between cluster heads of network and establish a cooperation of network scale. By this way, knowledge ranges of cluster head is enlarged efficiently. Simulating results indicate that this cooperation framework can manage the mobile nodes of k-hop clustered Ad Hoc networks and provide network scale cooperation efficicntly with moderate control overhead.
