A novel context-aware variable interval MAC protocol to enhance event-driven message delivery in IEEE 802.11 p/WAVE vehicular networks
S Babu, M Patra, CSR Murthy - Vehicular Communications, 2015 - Elsevier
Abstract Vehicular Ad hoc NETworks (VANETs) are the key to the future of Intelligent
Transportation Systems (ITS). In VANETs, event driven safety messages, generated for
example when an abnormal condition or an imminent danger is detected, have stringent
requirements on delay. However, due to the inherent drawbacks of CSMA which is used in
VANETs, such messages will not be able to meet the timing constraints in dense traffic
scenarios. In this paper, we introduce a Context Aware Variable Interval MAC (CAVI-MAC) …
