A new approach of wireless communication system using quality of service requirements system satisfaction

Abstract

During our autopsy, we studied and identified the main components of local wireless networks and presented some of the work of the scientific community on these same networks. Nevertheless, and despite the ambition of the MANET group, it is clear that all contributions on wireless networks is focused on the management of physical layers, access methods, mobility, routing. This is partly due to the complexity inherent in the layered construction of these networks. There has been no disruption of usage related to the proliferation of wireless networks: on the contrary, these networks are today mainly used as a local network for individuals to distribute access to the Internet. However, examples of new uses mentioned in MANET, such as mesh networks, are almost non-existent in current use; the few initiatives are the work of research groups, wishing to experiment the behavior of protocols on localized or groups of voluntary users, who take advantage of the possibilities of certain embedded hardware, such as some routers using Linux as an operating system to integrate routing functions into an 802.11 access point, and thus creating a community network, like the Citizen network in Belgium¹. However, from the very confession of the users, these networks are rather inefficient, and pose problems ranging from the setting up of new nodes, addressing, routing, naming, reaction times, security transferred data.
