Enhanced Qos in MANETs using Analysis of Routing Protocol

K. Venkataramana, P. Jaya Prakash, E. Prakash Babu


Mobile Ad hoc Network (MANET), is a self-configuring infra structure less network of mobile devices Connected by wireless links. ad hoc is Latin and means "for this purpose". Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. QOS is defined as a set of service requirements to be met by the network while transporting a packet stream from source to destination. Intrinsic to thenotion of QOS is an agreement or a guarantee by the network to provide a set of measurable pre-specified service attributesto the user in terms of delay, jitter, available bandwidth, packet loss, and so on. In this paper we are presenting two mobile ad-hoc routing protocols DSDV and AODV. Here the DSDV is a proactive protocol depending on routing tables which are maintained at each node. The AODV is a reactive protocol, which find a route to a destination on demand, whenever communication is needed. Considering the bandwidth, throughput and packet loss, in both DSDV and AODV routing protocols, DSDV is best suited for only smaller networks and AODV is suited for general Ad-hoc networks.
