Posted in: IEEE 2017, NS2
Performance Modeling and Analysis of the IEEE 802.11p EDCA Mechanism for VANET Abstract This paper studies performance modeling of the IEEE 802.11p enhanced distributed channel access (EDCA) mechanism and develops performance models to analyze the access performance of the IEEE802.11p EDCA mechanism. A 2-D Markov chain is first constructed to model the backoff procedure of an access category (AC) queue and establish a relationship between the transmission probability and collision probability of the AC queue.

Comments Off on Stability Challenges and Enhancements for Vehicular Channel Congestion Control Approaches
Posted in: IEEE 2017, NS2
Stability Challenges and Enhancements for Vehicular Channel Congestion Control Approaches Abstract Channel congestion is one of the major challenges for IEEE 802.11p-based vehicular networks. Unlesscontrolled, congestion increases with vehicle density, leading to high packet loss and degraded safety application performance. We study two classes of congestion control algorithms, i.e., reactive state-based and linear adaptive. In this paper, the reactive state-based approach is represented by the decentralized congestion control framework defined in […]
