Performance Comparison of AODV and DSR in MANET Test-Bed Based on Internet of Things

Mobile Ad hoc Network (MANET) is a collection of self-organizing wireless nodes without any fixed infrastructure and centralized administration. This article presents an investigation with an objective to compare the performance of two typical routing protocols, AODV and DSR, in real multi-hop environment. Apart from testing the end-to-end packet loss, delay and routing path parameters, we also assess the performance of AODV and DSR in terms of some applications based on Internet of Things (IOT), such as Radio Frequency Identification (RFID) service, voice service and temperature monitoring service. Two scenes are considered in this work: indoor pre-selected multi-hop scene with Media Access Control (MAC) filtering and outdoor self- organizing multi-hop scene with changeable and complicated wireless links. From the test results, it can be concluded that DSR has a better performance indoors while AODV can better adapt to outdoor complex electromagnetic environment. Additionally, the existing problems found in practical test are analyzed and the possible directions of future improvements in Ad hoc network test-bed are discussed.
