An M/MMGI/1/K queuing model is developed for the analysis of IEEE 802.11 DCF using RTS/CTS. Results are based on arbitrary contention conditions, namely, collision probabilities, transmission probabilities and contention window sizes vary arbitrarily among nodes contending for channel access. This is fundamentally different from earlier work. Results are(More)
Knowledge of the variations in renal vascular anatomy is important before laparoscopic donor or partial nephrectomy and vascular reconstruction for renal artery stenosis or abdominal aortic aneurysm. Recently, multidetector computed tomographic (MDCT) angiography has become a principal imaging investigation for assessment of the renal vasculature and has(More)
In this paper, two Markov chain queuing models have been developed to obtain closed-form solutions for packet delay and packet throughput distributions in a real-time wireless communication environment using IEEE 802.11 DCF. An M/G/1/K queuing model is incorporated in both models. In the first model results are based on arbitrary contention conditions,(More)
Hidden nodes are a basic problem that can potentially influence any multi-hop wireless networks where nodes cannot hear each other. Even though the hidden node problem is well known, its effects have not been quantified so well in a comprehensive manner up to now. This paper presents a novel framework for the queuing analysis towards getting a quantitative(More)
