“…In [5], the authors targeted Infotainment applications and showed through simulations that performance of bandwidth hungry applications suffers due contention based MAC scheme and delay generated due channel switching. The authors in [40] addressed the chance of contention to increase throughput, but the resulting bandwidth was not enough for multimedia applications. The results did not mention the overheads involved in W-HCF.…”

“…To resolve channel resource wastage problem, the interval adjustment approach can be purchased, wherein SCH interval is prolonged to help increase the opportunities of OBUs to access SCH, improve channel utilisation, and improve service, all in a performance-effective consideration Sheu et al, 2011;Wang et al, 2010). Additionally, the system throughput could be improved via making a schedule for the OBUs to access SCHs in a collision-free manner.…”

The wireless access in vehicular environment (WAVE) architecture has been standardised in the IEEE 802.11p specification in order to be widely deployed in roadway environments. The aim of the WAVE networks is to provide prompt emergency information as well as internet connectivity. However, the IEEE 802.11p contention-based medium access control (MAC) protocol would deteriorate transmission efficiency if the number of on-board units (OBUs) contending on an SCH is large. Moreover, synchronizing all WAVE devices that perform channel switching may experience a period of above-average channel congestion immediately following a channel switch, possibly resulting in an unexpectedly high collision rate. As a solution, we propose an efficiency improvement scheme, namely memorized carrier sense multiple access with collision avoidance (MCSMA/CA) protocol, which improves the SCH throughput by means of a channel context switch mechanism. Numerical and simulation results demonstrate that the proposed scheme significantly promotes the standard transmission efficiency.
