Selective Link Cost Alteration in Reservation-Based Multi-Hop Wireless Mesh Networks

Free registration required

Executive Summary

Link state protocol-driven wireless mesh networks are known for their flexible and highly scalable structure, due to a high degree of individuality, in terms of routing table generation in each connected node. QoS-focused research allows these nodes now to make accurate next-hop decisions based on QoS-sensitive routing metrics. This development enables significantly improved QoS-performance on the network layer. To further adapt link cost calculation to QoS-demands posed by digital media services on higher layers, the authors propose the Selective Link Cost Alteration (SLCA) scheme, which includes resource reservation demands into the process of neighbor link evaluation, in a distributed fashion.
