Composite metric for quality of service routing in OLSR
Nauman Aslam, William Phillips, William Robertson · 2004
Quality of service (QoS) support in mobile ad hoc networks (MANET) is a very challenging task because of the dynamic topology, limited resources and wireless link characteristics. The optimized link state routing protocol (OLSR) is a pro-active routing protocol for MANET. The metric used in OLSR protocol is hop count, which is not suitable for the wireless environment due to its inherent dynamic link characteristics. In this paper we discuss the different approaches used to add QoS functionality in OLSR. Most of these techniques are centered on using one or two performance metrics. We propose a composite metric using multiple parameters to find the optimal route given the QoS constraints.
