شبیه سازی مقاله Performance Enhancement of Reactive on Demand Routing Protocol in Wireless Ad Hoc Network
چکیده انگلیسی:
A Mobile Adhoc Network (MANET) is a class of wireless mobile nodes that dynamically organize themselves in arbitrary network topologies. Due to mobility of nodes, routing plays an important role in communication and routing protocols are divided into two basic classes: proactive and reactive. AODV is an on demand routing network protocol which is specially design for ad hoc networks. This protocol starts to, only when a certain node claims to send data and is an establish the route efficient ad hoc network routing protocol for data transfer. AODV suffers from the limitation of low bandwidth. In the AODV routing protocol, wherever a link breaks an error message is sent to the source indicating the link failure and further communication is stopped temporarily. This paper proposes an improved AODV routing protocol by including route repair scheme to overcome the link failure problems of its predecessor. In the proposed scheme the data packet is sent through alternate routes instead of dropping it. It is shown through simulation results that the proposed scheme improves data delivery rate.
