On-Demand Routing Protocols Performance Comparison in Wi-Fi Networks Based On Rainfall Intensity

During rainfall the information signal while transmission gets attenuated and the network performance is affected greatly in the regions where frequent rainfall occurs as they are prone to varying climatic conditions. Therefore in order to maintain a reliable communication the implementation of a MANET protocols during rainstorm or similar unfavorable environmental conditions should be paid great attention for the selection of routing protocols. The routing protocol must provide efficient and effective improvement in performance aspects such as total number of packets received, throughput, mean jitter and an end to end delay. This paper undergoes evaluation based study of MANET reactive/ on-demand routing protocols namely LANMAR, OSPFV2, ANODR and DYMO in Wi-Fi networks (IEEE802.11n). The behavior of routing protocols is simulated and evaluated using Exata 5.1 network simulator by varying the intensity level of rainfall from light rain (2mm/hr) to cloud burst (100 mm/hr) to predict rainfall efficient routing protocol which can render maximum throughput and minimum delay.
