Abstract:

This paper firstly analyzed the existing two authentication schemes,the centralized authentication scheme and the distributed authentication scheme before a new relay node accessing into the MMR WiMAX Network.Secondly a new hybrid authentication scheme was proposed based on the two existing authentication schemes.Then we used the queuing theory to analyze time-delay of the centralized and hybrid authentication scheme under different relay nodes distribution.Finally the results of numerical analysis show that the hybrid authentication scheme has great advantage in the performance of authentication time-delay compared with the centralized authentication scheme.

首先分析了在移动多跳中继(Mobile Multihop Relay,MMR)WiMAX网络中,新的移动中继(Relay Station,RS)节点在进入网络之前存在的两种认证方案:集中式和分布式接入认证方案。接着在这两种接入认证方式的基础上,提出了一种新的混合式认证方案。然后使用排队论对集中式和混合式认证方案在不同中继节点分布下的认证延时性能进行了分析。最后数值分析结果表明,混合式认证方案相较于集中式认证方案在认证延时性能方面具有更大的优势。
