Research on Routing Protocol Applied to Wireless Mesh Networks

leave a comment »

In Wireless Mesh Network conventional routing protocol can not be used because of difference in processing power, limited energy and less memory of nodes. So it was decided that it should have its own routing protocol. In this paper it was concluded that according to researchers that Dynamic Source Routing (DSR) is the protocol that provides most benefits. DSR routing protocol is improved by transmitting the packet based on distance threshold and congestion threshold. Results shows that each node forwarding becomes better i.e. network throughput has been greatly improved and broadcasting overload problem or congestion problems are reduced.

What is wireless mesh network?

leave a comment »

Wireless mesh networks (WMNs) have emerged as a key technology for next generation wireless networks showing rapid progress and inspiring numerous applications. WMNs seem to be significantly attractive to network operators for providing new applications that cannot be easily supported by other wireless technologies. The persistent driving force in the development of WMNs comes from their envisioned advantages, including extended coverage, robustness, dynamic self-configuration, easy maintenance, and lower operating costs.These characteristics allow WMNs to play an important role in the next generation of wireless network.
Wireless mesh network overcomes the drawbacks of traditional one hop wireless networks which are usually expensive and require licenses (e.g., 3G networks and licensed WiMAX) or have limited coverage (e.g., 802.11 WLANs). WMN are multihop wireless network, which require no infrastructure of its own and uses the existing infrastructure of these network .Thus WMN can be used to provide seamless connectivity on the go. Moreover, they can be used to provide broadband connectivity to the rural areas where service providers are not willing to deploy wired infrastructure which are more expensive and time-consuming to set up than a wireless one. One of the most attractive features of wireless mesh networks is self-organization. Various functions, such as medium access control and routing, are carried out in a fully distributed manner with minimal human intervention. They are not subject to any centralized network management processes of the kind practiced in wired networks. These attracted features of WMN have gained attention of research community and industries and a lot of research has been conducted in the last decade and is still being done regarding the issues of WMN implementation like routing and MAC layer design
