Abstract:
The wireless mesh network is a new emerging technology that will change the world of industrial networks connectivity to more efficient and profitable. Mesh networks consist of static wireless nodes and mobile customer; have emerged as a key technology for new generation networks. The QoS is designed to promote and support multimedia applications (audio and video), real time (ToIP, VoIP). However guarantee of QoS on wireless networks is a difficult problem by comparison at its deployment in a wired IP network. The reason is the random mobility of nodes, the nature of wireless channel (interference), the multi-hop communication and the lack of a central coordinating authority. Wireless Mesh Networks (WMNs) are commonly considered the most suitable architecture because of their versatility that allows flexible configurations. Different studies have proposed number of protocols in different layers of model TCP/IP to enhance transmission of data and its QoS. This paper mainly focuses on classification layer of the largest existing approaches dedicated to QoS. It is also discussing the most interesting works on QoS in WMNs networks.
