Abstracts: A Mobile Ad-Hoc Network (MANET) consists of a number of autonomous systems connected via wireless channels. MANETs are having highly dynamic structures as the nodes are mobile and can enter the network and leave the network at any instance of time. Mobile Ad-Hoc Networks can be established for communication between mobile nodes as per requirement. As communication environment is dynamic in MANET, routing of data packets is a crucial task. Despite dynamic nature of MANET it also faces several difficulties such as limited energy reservoir, routing overhead, etc. The task of routing packets from node to node in MANET is governed by routing protocols. . The primary objective of our project work is the implementation of AODV-UU protocol in MANET and analysing performance of Ad-Hoc on Demand Distance Vector (AODV) routing protocols and its variants. The performance analysis is done taking into account various qualitative and quantitative metrics. This analysis briefly describes the prominence of protocol according to the varying conditions. Performance differentials are analyzed by varying density of the network, pause times and movement speed. The performance analysis is based on different network metrics such as Packet Delivery Ratio (PDR), end-to-end delay, routing overhead and Throughput. The protocols considered for analysis are AODV (Ad-Hoc on Demand Distance Vector), AODV-UU (Ad-Hoc On demand Distance Vector – Uppsala University), AOMDV (Ad-Hoc On demand Multipath Distance Vector), and DYMO-UM (Dynamic MANET On demand – University of Marico’s). These simulations are carried out using the ns-2 network simulator. Simulations have been the driving force in development and evaluation of ad hoc routing protocols, but real world testing is currently lacking. So we have implemented a real-world network using APE (Ad hoc Protocol Evaluation) testbed.
