Performance Evaluation of LAR and OLSR Routing Protocols in Forest Fire Detection using Mobile Ad-Hoc Network

Objectives: To provide an assessment of two different types of MANET routing protocols. Methods/ Statistical Analysis: One of the key applications of the MANET technology include the disaster responding and the rescuing applications. Forest fires need a constant monitoring and an efficient communicative system. MANET includes several routing protocols. In spite of there being a large number of protocols, their performance in such disaster situations is ineffective due to high costs and a practical inability to recreate this scenario in a lab. Findings: The routing protocol performance was assessed using the MATLAB software. The different evaluation metrics that were adopted included the energy consumption, packet delivery ratio, routing overhead, and the end-to-end delay. Application/ Improvement: In our study, we have simulated a model for the forest fire disaster and have assessed two different routing protocols, i.e., the reactive Location-Aided Routing (LAR), and the proactive Optimised Link State Routing (OLSR). These protocols were evaluated to determine which is the more effective and reliable protocol amongst the two, in the case a forest fire disaster occurs. Our results have shown that the reactive LAR protocol was much better as compared to the proactive OLSR protocol as it showed better results for the Packet Delivery Ratio (PDR), energy consumption, and overheads, while the OLSR protocol has lesser values for the End-to-End Delay (E2E-Delay) parameter.
