Tradeoffs in PRACH Bandwidth Partitioning for VM2M Overlay Network in LTE
In this paper, we evaluate the impact of physical layer on the performance of the Control Channel (CCH) in a Vehicular Access Network (VANET). CCH is implemented as an overlay network over LTE physical random access channel (PRACH). Physical layer of the VM2M overlay uses dedicated Zadoff- Chu preambles while the medium access control (MAC) layer uses a carrier sense multiple access (CSMA/CA) mechanism. We study three deployment scenarios of VM2M overlay-based CCH and evaluate the performance tradeoffs between the VM2M and human to human (H2H) traffic, and show that the overlay is a feasible solution to implement the CCH in a VANET.
