Abstract
A Mobile Ad-hoc Networks (MANETs) are dynamic wireless networks that can be formed without the need for any existing infrastructure in which each node can act as a host as well as a router. One of the main challenges of MANETs is the design of robust routing protocols that adapt to the frequent and randomly changing network topology. A variety of routing protocols have been proposed and several of them have been extensively simulated or implemented. In this study, we compare and evaluate the performance of two reactive routing protocols namely: The Ad-hoc On-Demand distance Vector (AODV) routing protocol, which is unipath and Ad-hoc On-Demand Multipath Distance Vector (AOMDV) routing protocol. We observed that the results of AODV significantly outperformed that of the AOMDV in most cases contrary to the report that AOMDV outperformed AODV, but concerning in the literature that the selection of the mobility model has a significant impact the performance of the routing protocol.
Highlights
Introduction and MotivationThe development of wireless networks has brought about new prospects, e.g., Internet of Things (IoT), laptops and smartphones, for professional and private usage (Kocev et al, 2013)
Though the Packet Delivery Ratio (PDR) of Ad-hoc On-Demand Multipath Distance Vector (AOMDV) routing protocol increased tremendously at nodes 125, it still falls short of the Ad-hoc On-Demand Distance Vector (AODV) routing
This study examines the performance of AODV and AOMDV routing protocols with a more realistic mobility model
Summary
Introduction and MotivationThe development of wireless networks has brought about new prospects, e.g., Internet of Things (IoT), laptops and smartphones, for professional and private usage (Kocev et al, 2013). MANETs have received a lot of attention from the research community (Ofosu et al, 2018a; 2018b) Due to this feature of mobility, the network structure becomes unpredictable and changes frequently. The above discussion leads us to believe that it is significant to initially understand and evaluate the performance of the two most prominent MANET reactive routing protocols namely: Ad-hoc On-Demand Distance Vector (AODV) and Ad-hoc On-Demand Multipath Distance Vector (AOMDV) routing protocols, using a most realistic mobility model. Results from this analysis can be used to select the best base protocol for improvement
