ENHANCED WEIGHTED FAIR-QUEUING TECHNIQUE FOR IMPROVING THE QoS IN MANET

In MANET, the nodes are wirelessly linked to each other and the nodes are highly mobile. This makes the MANET topology highly dynamic. The communication between distant nodes occurs through several intermediate nodes, which act as router too. In MANET, the nodes depend on its battery power, which is limited. Also, the data packet being transmitted in this network have different priority; such as some data are real time and hence needs to be delivered at highest priority, whereas for other data types, some amount of delay does not create any problem. But, if these data packets are simultaneously transmitted with equal priority, then it will result in several issues like congestion, network breakdown, etc when the data traffic is high in the network. So, in this paper we develop a fair queuing technique in which the data packets are placed on the priority basis. Thus, ensuring QoS in the network.
