在这项工作中，我们介绍了我们在印度孟买附近的一个村庄管理无线网状网络部署以支持实时语音服务的经验。我们将重点放在我们部署的三个基本方面：(1)便于网络规划的网络内机制，(2)运行网络中的网络管理和数据收集，以及(3)用于长期网络维持的容错机制。特别是在实地资源有限、经常进行实地视察的农村部署方面，对这三个方面的考虑大大简化了我们的部署和衡量活动。我们的网络内机制不断提供所需的网络反馈，以应对现场的运营挑战。在基于TDMA的无线Mesh网络上，我们精心设计并实现了一个低开销、非侵入式的网络管理模块。在我们的部署过程中，此模块成功诊断了实时网络中的多个网络故障，并收集了所需的网络统计信息，而不会影响主要应用程序。我们还在原型中实现了一套容错机制，在我们的部署过程中，我们的网络证明了自己对各种网络故障的健壮性。村民们使用我们的网络一个多月，使用了一百多个语音呼叫，包括村内的本地电话和外部世界的远程电话。
In this work, we present our experiences of managing the deployment of a wireless mesh network to support real-time voice services in a village near Mumbai, India. We focus on three essential aspects of our deployment: (1) in-network mechanisms for ease of network planning, (2) network management and data collection in an operational network, and (3) fault-tolerance mechanisms for long-term network sustenance. Especially for rural deployment, where the amount of resources on the field are limited and frequent physical visits are costly, the consideration of these three aspects drastically simplified our deployment and measurement activities. Our in-network mechanisms constantly provided the desired network feedback to meet operational challenges while on the field. We carefully designed and implemented a low over-head and non-intrusive network management module over our TDMA based wireless mesh network. During our deployment, this module successfully diagnosed several network faults in a live network and collected required network statistics without affecting the primary application. We also implemented a set of fault-tolerance mechanisms in our prototype, and during our deployment, our network proved itself to be robust to various network failures. The villagers used our network for more than a month and availed more than hundred voice calls comprising of local calls within the village and remote calls to the phones in outside world.
