Nowadays mobile and ultramobile devices able to maintain a wireless connection with each other and to form a client mesh network are becoming more and more spred. The basic problem lies in optimal bandwidth sharing between a management traffic and a user one. On one hand it is necessary to provide effective routing and quick reaction on unit porting/disconnection, on the other hand a high-level service (QoS) of payload data transfer is extremely important too.
Only client mesh networks without any infrastructure elements such as servers, hubs, access points etc are being considered. That leads to more strict requirements for bandwidth sharing algorithms. They are:
The majority of modern IP-routing algorithms are directed to infrastructure networks what causes a number of essential deficiencies in their use for mesh networks. The disadvantages are:
Mesh network infrastructure model development
One of research directions is an adequate mesh networks model development which would take into account the particular qualities of modern wireless devices and ways of their usage (content exchange, teleconferences, games etc). In the context of model development it is intended to observe current states of algorithms, standards and routing protocols realizations for Ad Hoc and Mesh networks. The model should include:
Routing algorithm development
Mesh network infrastructure model is intended to help in developing of a routing/controlling algoritm for client mesh network that would provide adaptive bandwidth sharing between management and user traffic with considering of network topology and the way of its usage.
Open source realization
In the context of this project open source realization development is destined for XO laptops (OLPC, http://laptop.org) and its testing is proposed to take place in study rooms with such laptops.
