Wireless Mesh Networks (WMNs) are evolving to be the key technology of the future. The self-configuring nature of WMNs and the ease, with which a mesh router/mesh point can be added, makes it pertinent to ensure their secure operation. All the routing protocols in WMNs naively assume the nodes to be co-operative in forwarding each other’s packets. However, a node can behave selfishly by discret...

In spite of increasing international and academic attention, there remains many challenges facing real world implementations of developing technologies. There has been considerable hype behind Wireless Mesh Networking as the ubiquitous solution for rural ICT in the developing world. In this paper, we present the real world rural mesh network implementation in the village of Macha, Zambia and dr...

In service networks, discovery plays a crucial role as a layer where providers can be published and enumerated. This work focuses on the responsiveness of the discovery layer, the probability to operate successfully within a deadline, even in the presence of faults. It proposes a hierarchy of stochastic models for decentralized discovery and uses it to describe the discovery of a single service...

Mesh technology has captured the interest of university research and industry, because of its capacity to meet at the same time the requirements of Internet service provider and users. But, its architecture and configuration do not ensure a protection against the unauthorized use of the network since the used basic security measures do not include the concept of mobility. Our endeavor in this p...

In the last years Wireless Mesh Networks (WMNs) became more and more important and due to that the number of clients and the amount of data transferred over those networks grew constantly. The main reason why WMNs earned more attention is because they are an easy and cheap alternative to connect large areas with the internet, that maybe could not be connected with wires before. Conservative rou...

The present layout of the indoor wireless mesh network test-bed build at the Meraka Institute is introduced. This is followed by a description of a numerical electromagnetic model for the complete test-bed, including the coupling and diffraction effects, as generated with WIPL-D Pro. The results of numerical simulations are compared with the measurements. The findings help to quantify errors an...

The report details implementation of the infrastructure based wireless mesh networks, certain existing routing strategies and performance analysis of different topologies. The backbone of the network consists of a gateway, an access point, two routers and a client. The bandwidth obtained at these different nodes for different topologies were extensively studied and the phenomenon of bandwidth l...

Wireless mesh networking based on 802.11 wireless local area network (WLAN) has been actively explored for a few years. To improve the performance of WLAN mesh networks, a few new communication protocols have been developed in recent years. However, these solutions are usually proprietary and prevent WLAN mesh networks from interworking with each other. Thus, a standard becomes indispensable fo...

Wireless Mesh Networks (WMNs) have gained increasing attention as an attractive means to provide connectivity in complement to access as offered by regular Internet Service Providers (ISPs). Such a grass-root technique, however, often suffers from detrimental operating conditions and poor quality. Network virtualization, on the other hand, has been widely advocated as a possibility to overcome ...

In remote parts of Africa, the lack of energy supply, of wired infrastructure, of trained personnel and the limitation in OPEX and CAPEX impose stringent requirements on the network building blocks that support the communication infrastructure. Consequently, in this promising but untapped market, the research aims at designing and implementing energy-efficient, robust, reliable and affordable w...
