Wireless local area network is connected to the wireless nodes through router. When multiple users simultaneously start transmission, delay in data delivery and collision also increases many fold. Due to increase in collision and delay, throughput and delivery rate suffer enormously. To avoid these issues and to increase the network performance a new architecture as Localized Throughput Improvement Architecture (LTIA) is proposed. The LTIA consists of controller node to monitor the wireless nodes, to detect the node mobility and to queue data. When data is in queued, controller node assigns priority and allocate new channel medium for effective communication. The delay and collision reduces because assigning the new channel for every queued data. An analysis of experimental and simulation results with the constraints of quality of service parameters show that the performance of the proposed LTIA an increased throughput, delivery rate, bandwidth efficiency and decreases delay, collision probability and jitter.
