Roshni Neogy, Chandreyee Chowdhury, Sarmistha Neogy

摘要:

近年来,移动代理被用来发现移动自组织网络(MANET)中的服务,代理在网络中旅行,收集和有时传播动态变化的服务信息。但是,重要的是要调查如何可靠的代理是这个应用程序的可靠性问题(可靠性和可用性)的移动自组织网络的高度影响其动态natural.The底层的MANET的复杂性,很难获得的移动代理系统(MAS)的路由可靠性,而是我们估计它使用蒙特卡洛模拟。因此,一个算法估计的MAS(部署用于发现服务)的任务路由可靠性的建议,考虑到在移动自组网中的节点移动性的影响。通过考虑不同的移动模型,节点的移动模式影响MAS的性能。无线信号的多径传播效应被认为是决定链路存在的因素。还考虑了瞬时链路错误。最后,我们提出了一个度量来计算服务发现协议的可靠性,看看MAS性能如何影响协议的可靠性。实验结果表明了该算法的鲁棒性。在这里,为我们的应用程序计算网络带宽的最佳值(需要支持代理)。然而,MAS的可靠性是高度依赖于链路故障概率。

英文摘要:

Recently mobile agents are used to discover services in mobile ad-hoc network (MANET) where agents travel through the network, collecting and sometimes spreading the dynamically changing service information. But it is important to investigate how reliable the agents are for this application as the dependability issues(reliability and availability) of MANET are highly affected by its dynamic nature.The complexity of underlying MANET makes it hard to obtain the route reliability of the mobile agent systems (MAS); instead we estimate it using Monte Carlo simulation. Thus an algorithm for estimating the task route reliability of MAS (deployed for discovering services) is proposed, that takes into account the effect of node mobility in MANET. That mobility pattern of the nodes affects the MAS performance is also shown by considering different mobility models. Multipath propagation effect of radio signal is considered to decide link existence. Transient link errors are also considered. Finally we propose a metric to calculate the reliability of service discovery protocol and see how MAS performance affects the protocol reliability. The experimental results show the robustness of the proposed algorithm. Here the optimum value of network bandwidth (needed to support the agents) is calculated for our application. However the reliability of MAS is highly dependent on link failure probability.
