Abstract
Mobile Ad Hoc Networks (MANET) allows versatile communication between host devices moving around in a state of flux. These networks have no fixed infrastructure thus making the routing of packets a continuous challenge to be optimally delivered under varying criteria such as when the number of nodes within an area increases the scope for interference between nodes which also increases significantly. Additionally, MANETs have low stability in areas with fast moving nodes which leads to their reduced longevity. This paper proposes a method by adapting the standard Ad hoc On-Demand Distance Vector (AODV) protocol to dynamically adjust transmission power usage, which is titled Dynamic Power-Ad hoc On-Demand Distance Vector (DP-AODV). This method uses the dependence of a transmission range on density to achieve this improvement. The results demonstrate that as density increases, DP-AODV shows decrease in delay than AODV and offering better performance for highly populated networks exceeding 200 nodes. The simulation results show that DP-AODV increase network throughput whilst reducing the node interference in a dense region, as well as it enhances the overall network performance with respect to the increased packet delivery fraction, reducing the control overheads and jitter, enhancing overall throughput, reducing interferences and finally, shortening end-to-end delay in medium to high density conditions.
