Mobile Ad-hoc NETworks (MANETs) comprise on wireless mobile nodes that are communicating with each other without any infrastructure. Vehicular Ad-hoc NETwork (VANET) is a special type of MANETs in which vehicles with high mobility need to communicate with each other. In this paper, the authors present a novel framework for link availability of paths for static as well as dynamic networks. Moreover, they evaluate their framework for routing protocols performance with different number of nodes in MANETs and in VANETs. They select three routing protocols namely Ad-hoc On-demand Distance Vector (AODV), Fish-eye State Routing (FSR) and Optimized Link State Routing (OLSR). Furthermore, they have also modified default parameters of selected protocols to check their efficiencies.
