  1. Improving Geographical AODV Protocol by Dynamically Adjusting the Request ZoneRemo Cocco, Vasil Hnatyshin*, Malik Ahmed, Dan UrbanoDepartment of Computer Science, Rowan University{coccor22, ahmedm16, urbano51}@students.rowan.edu, *hnatyshin@rowan.edu Purpose of AODV Simulation Set-up • MANET are mobile ad hoc networks • MANET are decentralized networks without pre-existing infrastructure • MANET nodes are mobile wireless devices that can operate as a source, destination, and a router • MANETs have various uses including disaster recovery and inter-vehicle communication • AODV – Ad-hoc on-demand distance vector routing protocol for MANET • AODV use network flooding to find the path to destination • The node travel with the speed uniformly distributed between [0, 20] meters/second • Nodes use default WLAN configuration A Solution • Assume that every node in the network has a GPS device • Use node’s location coordinates to determine the direction of the route discovery process • Explore only the area of the network that is likely to contain a route to destination (called a Request Zone) • The Request Zone is a cone-shaped area formed between the source and destination • Only nodes located within the Request zone participate in the route discovery • Compute Request zone via flooding angle The Problem The Results • Network flooding sends an incoming packet on all outgoing interfaces • Network flooding causes unnecessary traffic overhead by exploring unpromising paths A Better Solution • OPNET Modeler is a network simulation software tool • 80% of the Fortune 100 use OPNET’s Performance Management solutions. • Rowan received a license grant from OPNET Inc. worth over $2,000,000 • Recalculate the request zone at every node • Redirect request zone towards the destination • New optimization further reduces the traffic overhead
