Investigation into BATMANd-0.3.2 Protocol Performance in an Indoor Mesh Potato Testbed

In this paper, we describe the performance of the B.A.T.M.A.N daemon (Batmand) protocol on an indoor Mesh Potato (MP) testbed. The MPs are small devices used for voice communications over the wireless medium but also supports data. The batmand protocol is designed for ad hoc wireless networks. We measure delay, packet loss in order to understand the MPs network performance. The experiments used packets of varying sizes over multiple hops. We analyze the data to see if the network latency for up to four hops is within the recommended boundaries set by ITU-Recommendation G. 114. We also observe the how the network’s performance is affected by the varying packet sizes. Finally the experiments also reveal the common issues found on the wireless medium and also indoor testbeds

Investigation into Batman-adv Protocol Performance in an Indoor Mesh Potato Testbed

In this paper, we describe the performance of the B.A.T.M.A.N advanced (Batman-adv) protocol on an indoor Mesh Potato (MP) testbed. The MPs are small devices used for voice communications over the wireless medium but also supports data. The Batman-adv protocol is designed for ad hoc wireless networks. We measure delay and packet loss, jitter and throughput in order to understand the MPs network performance. The experiments used packets of varying sizes over multiple hops. We analyze the data to see if the network latency for up to four hops is within the recommended boundaries set by ITU-Recommendation G. 114. We also observe the how the network’s performance is affected by the varying packet sizes. Finally the experiments also reveal the common issues found on the wireless medium and also indoor testbeds

Evaluación de protocolos de encaminamiento en una red inalámbrica mallada desplegada en una zona rural

The implementation of wireless communication systems in rural areas through the deployment of data networks in infrastructure mode is often inadequate due to its high cost and no fault tolerant centralized structure. Mesh networks can overcome these limitations while increases the coverage area in a more flexible way. This paper proposes the performance evaluation of the routing protocols IEEE 802.11s and Batman-Adv on an experimental wireless mesh network deployed in a rural environment called Lachocc, which is a community located at 4700 MASL in the Huancavelica region in Peru. The evaluation was based on the measurement of quality of service parameters such as bandwidth, delay and delay variation. As a result, it was determined that both protocols offer a good performance, but in most of the cases, Batman-Adv provides slightly better performanc

Voice and rural wireless mesh community networks: a framework to quantify scalability and manage end-user smartphone battery consumption

Philosophiae Doctor - PhDCommunity wireless mesh initiatives are a pioneering option to cheap ‘last-mile’ access to network services for rural low-income regions primarily located in Sub-Saharan Africa and Developing Asia. However, researchers have criticized wireless mesh networks for their poor scalability; and scalability quantification research has mostly consisted of modularization of per-node throughput capacity behaviour. A scalability quantification model to design wireless mesh networks to provide adequate quality of service is lacking. However, scalability quantification of community mesh networks alone is inadequate because rural users need affordable devices for access; and they need to know how best to use them. Low-cost low-end smartphones offer handset affordability solutions but require smart management of their small capacity battery. Related work supports the usage of Wi-Fi for communication because it is shown to consume less battery than 2G, 3G or Bluetooth. However, a model to compare Wi-Fi battery consumption amongst different low-end smartphones is missing, as is a comparison of different over-the-top communication applications

Estudio e implementación de protocolos de enrutamiento de redes malladas inalámbricas en entornos rurales

Este proyecto surge de la problemática de llevar las tecnologías de la información a las zonas más alejadas e inaccesibles, donde generalmente se dan los mayores índices de pobreza. Para ello se propone el estudio de la viabilidad de las redes malladas inalámbricas aplicadas en entornos rurales. Las redes malladas tienen una filosofía distribuida que permite mayores coberturas con un menor presupuesto, además de ofrecer una mayor seguridad en caso de catástrofes y una gran independencia de las grandes redes de los proveedores de Internet. Esto hace que puedan ser una interesante alternativa a las redes de comunicación inalámbrica convencionales. En primer lugar se intenta analizar cu ́les son los protocolos de encaminamiento más adecuados para redes malladas en este tipo de escenarios rurales, donde el medio inalámbrico es adverso e inestable y la logística es más complicada. En concreto, se ha desplegado para su posterior estudio, una red experimental rural en un entorno altoandino. En dicha red se comparan dos soluciones de encaminamiento de código abierto, Batman-adv y IEEE 802.11s. Adicionalmente, el proyecto intentar difundir la tecnología y transferir los conocimientos aprendidos a través de diversos talleres de capacitación,artículo técnico sobre la comparación de las prestaciones Batman-adv y IEEE 802.11s, y la creación de un proyecto de red comunitaria libre llamado MESH-RURAL, el cual facilitar ́ la implementación de redes malladas inalámbricas con estas dos soluciones de encaminamiento
