Abstract
Mobile Ad-hoc Networks (MANETs) are mobile, multi-hop wireless networks that can be set up anytime, anywhere without the need of pre-existing infrastructure. Due to its dynamic topology the main challenge in such networks is to design dynamic routing protocols, which are efficient in terms of consumption of energy and producing less overhead. The main emphasis of this research is upon the prominent issues of MANETs such as energy efficiency and scalability along with some traditional performance metrics for performance evaluation. Two proactive routing protocols used in this research are single-path AODV versus multi-path AOMDV. Extensive simulation has been done in NS2 simulator, which includes ten scenarios. The simulation results revealed that the performance of AOMDV is more optimal as compared to AODV in terms of throughput, packet delivery fraction and end to end delay. However, in terms of consumption of energy and NRL the AODV protocol performed better as compared to AOMDV.
Highlights
In Mobile Ad-hoc Networks (MANETs) the mobile nodes can connect dynamically using a variety of wireless media without any centralized infrastructure [1]
Performance Metrics Used in Simulation In order to evaluate the performance of Ad hoc On-Demand Distance Vector (AODV) and AOMDV, we considered the eight most commonly used quantitative indicators to judge the performance of the protocols: (1) Total Energy consumed by all nodes (TE); (2) Average Consumed Energy (ACE); (3) Average Residual Energy (ARE); (4) Packet Delivery Fraction (PDF); (5) Throughput Rate [kbps]; (6) End-to-End delay (E2ED); (7) Routing Load and (8) Normalized Routing Load
This research provides a paradigm for future studies for the development of dynamic routing protocols, which are more efficient and effective in terms of energy consumption and producing less overhead
Summary
In Mobile Ad-hoc Networks (MANETs) the mobile nodes can connect dynamically using a variety of wireless media without any centralized infrastructure [1]. The mobility of the nodes in MANETs can cause the links to break due to which the nodes recalculate routing information in order to establish the links. This process consumes power, processing time, memory and produces additional traffic [4]. The potential of the Ad-hoc networks is that it can be used in the situations where infrastructure is not available and technically not possible to deploy such as disaster and military operations. The situations can include low power sensor networks [5]
