Abstract:

Wireless and mobile technology is rapidly gaining in popularity in both home and business networking and has become quickly a promising technology in today’s emerging technologies. The advantages of wireless transmission include mobility and elimination of cables while its disadvantages include the potential for radio interference due to weather, other wireless devices, or physical obtrusions such as walls. A new type of broadband access network known as wireless mesh network (WMN) enhances the potentials of wireless and mobile networks by using the wireless mesh routers and wireless mesh clients. The main characteristic of a WMN is that the nodes at the core of the network are responsible for forwarding data to and fro clients, forming thus the Mobile and Ad- hoc Network (MANET). Unfortunately, the inherent shortcomings of WMNs, such as dynamic topology, the limitations of mobile terminals and heterogeneity makes it’s end to end QOS become very difficult and challenging.  In this work, we propose an MPLS internetworking approach that builds on the capability of traffic engineering in an IP-network by identifying traffic flows by labels and creating explicit routes (label switching paths (LSPs) for various traffic flows to solve these challenges. This approach uses ATM technology to address certain issues of WMNs such as reliable handoff procedure, bandwidth management, distributions of traffics as well as capacity. The theoretical aspects related to this MPLS protocol, its functionality, strengths and weaknesses as well as their implementations were discussed. The unsuitability of WMNs for Traffic Engineering and efficient resource allocation was also discussed.
