Performance Analysis of TS-AODV and MTS-AODV Routing Protocols in MANET

Abstract

A Mobile Ad-hoc Network (MANET) is a group of wireless nodes that are communicating with each other within radio range without help of infrastructure based or any centralized administration.  As the nodes are mobile so topology changes frequently that leads to link failure and lack of infrastructure support and resource constraint is the key issue that causes dishonest and non co-operative nodes.  There are finding a route to destination, new route discovery is initiated.  The frequent discoveries lead to more network congestion.  To avoid this multipath routing protocols have been proposed to find multiple routes to destination and switch on to alternate secondary path in case of route broken and its provide better routing performance and security. In this technical research paper attempt to compare the performance of two reactive routing protocols for MANETs that is Trusted Secure Ad-hoc On-Demand Distance Vector (TS-AODV) and Modified Trusted Secure Ad-hoc On-Demand Distance Vector (MTS-AODV).  TS-AODV is on-demand gateway discovery protocol where a mobile device of MANET gets connected to gateway.  MTS-AODV is based on the node routing behaviour and identifying the attacks such as flooding, black hole, gray hole and denial of service attacks in MANET.  MTS-AODV using the Intrusion Detection system (IDS) and trust based routing, the performance results are analysed by varying simulation time.  Furthermore, all the above mentioned protocols are compared based on several important performance metrics which are packet delivery ratio, end-to-end delay and average energy.
