针对当前语义缓存一致性维护策略难以适应移动终端频繁切换、断接的问题,提出使用移动代理技术来维护语义缓存一致性的方法.首先,基于SMC-架构设计移动代理MSSAg和MTAg;其次,提出无小区切换和有小区切换2种情况下进行缓存一致性维护的方法.实验结果表明,所提方法在减少缓存一致性恢复时间和降低网络通信量方面较其他算法有明显的改善,可以有效地在频繁断接、移动和切换的环境中进行语义缓存一致性维护.
Aiming at the problem that current semantic cache coherency maintenance strategy is difficult to adapt to the problem of frequent handoff and disconnection of mobile terminals, a method of using mobile agent technology to maintain semantic cache coherence is proposed.Firstly, mobile agent MSSAg and MTAg are designed based on SMC-architecture. Secondly, There is no cell handover and there are two cases of cell switching cache consistency maintenance methods.Experimental results show that the proposed method in reducing cache coherency recovery time and reduce network traffic significantly improved than other algorithms can effectively Semantic cache coherency maintenance in frequently disconnected, moved, and switched environments.
