Opportunistic management of spontaneous and heterogeneous wireless mesh networks [Accepted from Open Call]

In the traditional model for wireless mesh networks, a two-tiered architecture classifies nodes into mesh routers or clients. Such an approach, based on strong separation of roles, is interesting when an administrative entity deploys and controls the network. Nevertheless, in spontaneous and self-organized networks, where there is no administrative entity behind the network formation, this model does not hold anymore. In such a scenario the heterogeneity of nodes should be fully exploited in order to increase, as much as possible, network availability and usability. In this article we propose an approach for opportunistic wireless mesh network formation and maintenance that breaks the rigidness of the traditional architecture. We relax the role separation constraint and consider the case of spontaneous network formation relying on the concept of self-organization and collaboration. The main idea is to make the network take advantage of the specific resources and characteristics of the nodes in an opportunistic fashion. In our vision, any node (routers and clients) can perform any network functionality, if they can and if they wish.

EPEW: An extended prototyping environment for wireless mesh networks

This paper introduces EPEW, an environment for rapid prototyping of communication protocols over IEEE 802.11 mesh networks. EPEW provides a software environment that makes prototyping as quick, easy, and effortless as possible, which allows researchers to conduct both functional assessment and performance evaluation as an integral part of the protocol design process. Since EPEW runs on real IEEE 802.11 wireless mesh routers and clients, prototypes can be evaluated and adjusted under realistic conditions. EPEW facilitates prototype development by providing: (i) a set of building blocks that implement common functions needed by a wide range of protocols for wireless mesh networks, and (ii) an API that allows protocol designers to access EPEW primitives.
