ABSTRACT
An in-depth analysis of the AODV and OLSR routing protocols was performed in this study based on different scenarios to obtain a comprehensive insight into the performance features of MANETs. Several important metrics have evaluated rigorously such as the average energy consumption, packet loss, delay, Packet Delivery Ratio (PDR) and routing overhead. AODV shows higher packet loss (19.50%) and better PDR (84.6%) on average in comparison to the default OLSR implementation (77.45%). In the latency statistics, AODV had a 0.1722 ms delay while OLSR recorded a time of millisecond delay of 0.022. concerning energy efficiency, AODV was more efficient as it averaged power usage of 78.38 J compared to OLSR which has an average power consumption quality value of 145.82 J.II examining routing overhead default cost showed that OLSR has hence defaults with a higher value (774) compared to AODVs’ thirty-nine seen above(common). The changes in parameter values have significantly affected the performance indicators, especially for parameters REQ_RETRIES and OUTTIME_MREQ. These results and observations give insights of use for future improvements within mobile communication systems in order to increase network resilience, as well as MANET protocol optimization.
