摘要
在分析与研究Ekta与MDPastry系统基础上,采用Kademlia作为DHT覆盖层协议,DSR作为网络层协议,本文提出了一种新型的基于Ad Hoc网络的DHT系统——MDKademlia。该系统优化了Kademlia的路由表及其维护机制,同时通过对RLM算法的改进,本文提出了ORLM算法实现节点的动态聚簇,降低了冗余的网络负载,增强了系统的可扩展性。仿真实验结果表明,本系统的路由成功率和网络负载两个关键指标均较为理想。
This paper presents a new DHT system called MDKademlia based on mobile ad hoc networks after analyzing and studying these two systems Ekta and Pastry. It optimizes both the routing algorithm and the muting table maintenance mechanism of Kademlia and DStL By studying and improving the RLM algorithm, the paper proposes the ORLM algorithm for the dynamic clustering of nodes. The results of simulation indicate that the two key indexes of the system, namely the muting success rato and the network overhead,are satisfactory.
