On the Construction of QoS Based Overlay Architecture for Wireless Local Area Network

Wireless local area network is mostly used in home and office buildings within limited coverage area and for limited users. To increase the coverage range and number of users, we have introduced different types of overlay architectures with the help of controlled load virtual link. This type of virtual links will increase the collision and delay due to heavy traffic. The service overlay network is utilizes more bandwidth that reduces the throughput. To overcome all those issues, we proposed a new architecture as quality of service (QoS) based overlay architecture. This architecture uses the gateway nodes between the overlay nodes that will monitor the status of the channel medium and intimate about the medium to all the overlay nodes to reduce the delay and collision during the high traffic condition. This proposed QoS based overlay architecture increases the throughput and delivery rate. Simulation results analyze the performance of the proposed QoS based overlay architecture by using the QoS parameters. This proposed QoS based overlay architecture increases the overall network performance in different levels of gateway nodes.
