Managing the virtual collision in IEEE 802.11e EDCA
The IEEE 802.11e EDCA is the distributed channel access mechanism introduced by the Quality of Service amendment to the IEEE 802.11 standard. This mechanism introduces differentiation to the channel access. This led to the introduction of the principle of the virtual collision. We study, in this paper, the effect of the virtual collision management as presented by EDCA on its fairness among oth...
متن کاملRevisiting the Markov Chain Model of IEEE 802.11E EDCA and Introducing the Virtual Collision Phenomenon
IEEE 802.11e specifies the Enhanced Distributed Channel Access (EDCA) for distributed access with traffic differentiation to a Wireless Local Area Network (WLAN). Traffic differentiation led to introducing several traffic queues within each station, thus introducing virtual collision. In this paper, we present a pattern based Markov chain model of EDCA including the virtual collision phenomenon...
متن کاملDetecting backoff misbehaviour in IEEE 802.11 EDCA
In this paper, we suggest the use of the chi-square test for detecting backoff misbehaviour in IEEE 802.11 EDCA networks. A performance evaluation is performed to compare the chi-square test with two other methods, known in the literature. To perform a suitable comparison, these two methods are extended to support EDCA and the BEB mechanism. We assume a misbehaviour model, which can be easily e...
متن کاملPerformance Study of IEEE 802.11 DCF and IEEE 802.11e EDCA
One of the key factors for the wide acceptance and deployment of IEEE 802.11 Wireless Local Area Networks (WLANs) is the simplicity and robustness of the Medium Access Control (MAC) protocol. Based on the well-known carrier sense paradigm, with an exponential backoff mechanism devised to minimize the probability of simultaneous transmission attempts by multiple stations, the protocol is able to...
متن کاملA Synthetic model of IEEE 802.11e EDCA
This paper proposes a very simple reduced abstract model of the behavior of the EDCA (Enhanced Distributed Channel Access) access mode with respect to an access category under saturation. This model is derived from a Markov chain model of EDCA using reduction techniques. Closed-form expressions of common performance metrics (i.e. mean throughput, mean access delay and packet drop probability of...
