Performance Analysis of Ad-hoc On-demand Distance Victor and Destination Sequenced Distance Vector protocols

Abstract

A mobile ad hoc network (MANET) can be defined as a set of wireless nodes or routers coming together to form a network in which every node acts as a router, the mobile nodes are free to move randomly. There are some challenges that face these networks such as energy efficiency and power consumption duo to limited energy of the nodes, difficulty lies in replacing the batteries, lack of central coordination and constraints on the battery source. So in this thesis the problem of energy is considered and it will focus on two protocols; Ad-hoc On-demand Distance Vector Protocol (AODV) and Destination Sequenced Distance Vector Protocol (DSDV). The protocols are implemented using ns-2.35. This thesis compares two protocols while considering Packet Delivery Ratio (PDR), packet loss, Average end to end delay (E2E), Throughput, power consumption and number of nodes as performance metrics. The simulation results indicate that; packet delivery ratio (PDR) in AODV is better than DSDV. In AODV it is better by 76.5% in 5m/s, in 10m/s AODV is better by 69.8% and in 15m/s it is 60.26% in the average. AODV has more throughput as compared to DSDV. At 5m/s AODV is better than DSDV by 82.4%. While at 10m/s and 15m/s AODV it is better than DSDV by 72% in the average. The AODV achieves high End-to-End delay due to its hop-by-hop routing methodology and DSDV losses packet more than AODV; at 5m/s and at 10m/s DSDV losses more packets than AODV by 96.9% and at 15m/s DSDV losses more packets than AODV by 88.5% in the average. Although AODV has achieved a higher throughput, higher PDR and lower packet losses; for energy consumption DSDV has consumed less energy; with 5m/s as mobility speed to both sources; AODV consumes more energy by 35.2%. In both destinations with 5m/s as mobility speed AODV consumes 64.2% more energy than DSDV in the average.
