Abstract

One of the major shortcomings of Optimized Link State Routing (OLSR) [RFC3626] is the lack of a granular link-cost metric between OLSR routers. Operational experience with OLSR networks gathered since its publication has revealed that wireless networks links can have highly variable and heterogeneous properties. This makes a hop-count metric insufficient for effective OLSR routing.
