A Simulation Based Study of Routing Protocols in Mobile Ad-hoc Networks

Abstract


 Mobile ad-hoc is a temporary network without a pre-established infrastructure. Because of the absence of centralized structure, mobile ad hoc networks are facing several problems such as security, routing, limitation of bandwidth, energy and hidden terminal, which need efficacious solutions. Ad-hoc on-demand distance vector (AODV) is a reactive protocol. Mobile ad-hoc on-demand data delivery protocol (MAODDP) is new addition in reactive protocols. It can support both unicast and multicast routing. In this thesis, I evaluate and compare the performances of AODV and MAODDP by means of simulation using SWAN. From the experiments for MAODDP, we see that Route Query and Data Delivery Packet (RQDD), Acknowledge Message (ACK), and routes are increasing with increasing nodes, but these are increasing more sharply than Route Request (RREQ), Route Replies (RREP) and routes for AODV. These observations notify that MAODDP is safer than AODV because more data query and data delivery make routing trustworthy and reliable. ACK and RREP both are increasing, but there is a big difference between ACK and RREP increase. The increase of ACK messages informs us that MAODDP is more dependable in routing table compared with AODV. The most important observation is in energy consumption. AODV saves more energy than MAODDP with a number of nodes up 150. However, MAODDP starts saving more energy than AODP with 200 nodes and this information tells us that MAODDP is more capable for a large network.
