Abstract

A Mobile Ad hoc Network (MANETs) is a group of wireless mobile terminals, which cooperate together by routing packets to each other on a temporary network. MANETs are attracting attention for their potential use in several fields such as collaborative computing and communications in indoor and outdoor environments. Considering mobility of the terminals, routing is a key process for operation of MANETs. In this paper, we analyze the performance of Optimized Link State Routing (OLSR) protocol in a mixed indoor and outdoor environment considering different scenarios (STA1, STA2, MOV) for horizontal topology. We evaluate the scenarios based on throughput and delay metrics. From the experimental results, we found that for STA1 scenario, there is a decrease in performance in the case of rightarrow-4 flow, for both metrics, because of the hop distance. For STA2 scenario, the presence of node 5 improves route quality for rightarrow-4 flow. When destination node is moving (MOV scenario), the delay and throughput decreased because it becomes difficult to keep the route to the destination.

室内外混合环境下MANET试验台性能评价

移动自组网(manet)是一组无线移动终端，它们在一个临时网络中通过相互路由数据包的方式相互协作。manet因其在室内和室外环境中的协作计算和通信等多个领域的潜在用途而引起人们的关注。考虑到终端的移动性，路由是城域网运行的关键环节。本文分析了水平拓扑下不同场景(STA1、STA2、MOV)下，优化链路状态路由(OLSR)协议在室内和室外混合环境下的性能。我们基于吞吐量和延迟度量来评估场景。从实验结果中，我们发现，对于STA1场景，由于跳距离的原因，在右箭头4流的情况下，两个指标的性能都有所下降。对于STA2场景，节点5的存在提高了右4流的路由质量。当目的节点移动时(MOV场景)，由于难以保持到目的节点的路由，延迟和吞吐量下降。
