Puneet Bindra, Jaswinder Kaur, Gurjeevan Singh . Enhancing Quality of Service in ERS- AODV for Mobile Ad Hoc Networks. International Journal of Computer Applications. 76, 10 ( August 2013), 14-18. DOI=10.5120/13282-0583
Abstract
A MANET is a wireless network which operates by themselves without centralized administration. Each node in MANET operates as an end system and a router for all other nodes in the network. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route the traffic. Reactive routing protocols are favoured in MANET's because they generate fewer overheads in network. These protocols suffer due to network flooding in route discovery process. Expanding ring search in terms of early detection of destination cause quality of service to fluctuate randomly. Performance degradation due to quality of service is a bottleneck to fulfill stability and reliability in MANET's. In this paper, a scheme is introduced for controlling the broadcasting of RREQ information focusing on improved quality of service in AODV (Ad hoc on Demand Distance Vector) routing protocol. This is achieved by monitoring the TTL start, TTL increment and TTL threshold values of network and choosing optimum values of TTL suitable to network designed that accounts for reliability and quality of service during route discovery process. It is simulated using OPNET 14. 5 with fixed node density.
