TAILIEUCHUNG - A contribution to performance analysis approach of the IEEE 802.11 EDCA in wireless multi hop networks

This paper proposes an analytical model which covers full specification of IEEE EDCA. To reduce the complexity, the model is simplified by decomposing the problem in two models based on Markov chain that can be easily solved by numerical method. The proposed model is presented in the theoretical aspect as well as numerical results to clarify its accuracy. | VNU Journal of Science: Comp. Science & Com. Eng., Vol. 31, No. 1 (2015) 45-54 A Contribution to Performance Analysis Approach of the IEEE EDCA in Wireless Multi-hop Networks Minh Trong Hoang*, Minh Hoang, Duc Cong Le Posts and Telecommunications Institute of Technology, Hanoi, Vietnam Abstract The IEEE standard has been introduced to support service differentiation for wireless local area networks. In wireless multi-hop networks, the performance of IEEE EDCA has to confront with some practical problems such as unsaturation traffic and hidden node problem. Hence, this problem has attracted numerous studies in recent years, in which several investigations use analytic model to evaluate the performance due to its accuracy aspect. However, the accuracy and complexity of analytical model depends on a range of assumed parameters. The complexity caused by the introduction of realistic conditions in wireless multi-hop networks is the major challenge of current studies in this field. To overcome this challenge, this paper proposes an analytical model which covers full specification of IEEE EDCA. To reduce the complexity, the model is simplified by decomposing the problem in two models based on Markov chain that can be easily solved by numerical method. The proposed model is presented in the theoretical aspect as well as numerical results to clarify its accuracy. © 2015 Published by VNU Journal of Science.
