Abstract
A challenging issue for (MANETs) is finding an effective routing mechanism, the wireless connection must have the capability to interact while traveling randomly, since MANETs are self-configuring mobile node networks. Traditional fixed network routing protocols are useless with MANET. Based on this, MANETs introduced new routing protocols. In this study, the routing process was investigated, particularly (DSR), (AODV) and (DSDV). Simulations are implemented in the NS2 simulation environment and evaluated their performance under various scenarios. The results of the simulation study were summarized with a number of graphs using NAM (Network Animation Environment) and Trace Graph programs and a general evaluation was made. The results of the simulation studies presented that DSR and AODV showed better efficiency than the table based DSDV protocol. In addition, DSR and AODV protocols may present a variable performance for the different data packets and network sizes due to their algorithmic differences.
Highlights
MANET is a set of mobile nodes with infrastructure-free networks
This study looked at the behavior of reactive Ad-hoc on-demand distance vector routing protocol (AODV), Dynamic source routing protocol (DSR), and proactive Destination-sequenced distance vector routing protocol (DSDV) routing protocols with settings and parameters for each protocol given in the network simulator table
AODV, on the other hand, uses the method of routing tables, destination sequence numbers, loops and determining whether or not the route exists, as a route to the destination. According to the simulation outputs, the DSDV indicates a decrease in the number of the packet sent and received as the number of nodes increases and the reason behind is that the DSDV protocol must notify the nodes on the network before sending the packet
Summary
MANET is a set of mobile nodes with infrastructure-free networks. These nodes generate temporary networks without the help of centralized or standard devices that are regularly supported on traditional networks [2], [3]. DSDV, DSR, and AODV routing protocols evaluation were done by simulation in the NS-2 simulation environment
