A Comparative Performance Analysis of MANETs Routing Protocols in Trust-Based Models

摘要

Mobile ad hoc Network (MANET) consists of autonomous mobile nodes without any centralized control. These mobile nodes move arbitrarily within the self-configurable MANET environment. Each of these mobile nodes can act as router while receiving and forwarding information. Secure routing is an important issue in MANET as mobile nodes are prone to attacks from malicious nodes and the overall performance of the network depends on it. In this setting, three routing protocols have been analyzed and compared: OLSR, DSR and AODV. The metrics are being used are Packet Delivery Ratio, Delay and Throughput. Network Simulator (NS2) has been used as tool for the experiments. The performance analysis of these protocols also compared for power usage using two trust-based models: Node based Trust Management (NTM) Scheme and TLEACH. Simulation results show that OLSR protocol performs well compared to AODV and DSR.
