Executive Summary

This paper presents the link availability probability. The authors evaluate and compare the link availability probability for routing protocols; Ad hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Fisheye State Routing (FSR) for different number of connections and node density. A novel contribution of this work is enhancement in existing parameters of routing protocols; AODV, DSR and FSR as MOD-AODV, MOD-DSR and MOD-FSR. From the results, they observe that MOD-DSR and DSR outperform MOD-AODV, AODV, MODOLSR and OLSR in terms of Packet Delivery Ratio (PDR), Average End-To-End Delay (AE2ED), and link availability probability at the cost of high value of Normalized Routing Overhead (NRO).
