In this paper we developed Quality of service model for wireless networks. We also applied error control protocol for the transmission states. Three backoff strategies are applied. Analytical models are developed. The performance metrics measured by the throughput, acceptance probability, delay and energy are studied. In the error control protocol, the(More)
In this paper we develop an intergraded model for request mechanism and data transmission in the uplink phase in the presence of channel noise. This model supports quality of service. The wireless channel is prone to many impairments. Thus, certain techniques have to be developed to deliver data to the receiver. We calculated the performance parameters for(More)
In this paper we develop an integrated model for request mechanism and data transmission in multi-channel wireless local area networks. We calculated the performance parameters for single and multi-channel wireless networks when the channel is noisy. The proposed model is general it can be applied to different wireless networks such as IEEE802.11x,(More)
