Abstract

Nowadays wireless systems changing our life experience, allowing ubiquitous communications, attracting new users, and supporting new applications, such as video streaming, VoIP, Mobile TV and other kind of multimedia applications. The combination of wireless networks and multimedia content distribution requires a new behavior of routing protocols for Wireless Mesh Networks (WMNs). Hence, new protocols must be developed to increase the user perception and optimize the usage of network resources. This paper presents a variation of the WMN routing protocol Optimized Link State Routing (OLSR), to achieve QoS and QoE requirements for multimedia applications. It is based on the dynamic choice of metrics and in a Fuzzy Link Cost (FLC) to determine the best routes for multimedia packets. Simulations were carried out to show the benefits of the proposed metric regarding user experience compared to existing versions of OLSR.
