IEEE 802.11p is an emerging standard designed to provide wireless access in a vehicular environment. A major application of 802.11p-based Dedicated Short Range Communications (DSRC) is Vehicle to Vehicle (V2V) safety messaging. The US FCC has designated 75 MHz of bandwidth in the 5.9GHz band to support DSRC with a maximum permissible transmit power level of(More)
The throughput of large wireless networks with regular topologies is analyzed under two medium-access control schemes: synchronous array method (SAM) and slotted ALOHA. The regular topologies considered are square, hexagon, and triangle. Both nonfading channels and Rayleigh fading channels are examined. Furthermore, both omnidirectional antennas and(More)
A distributed and cooperative link-scheduling (DCLS) algorithm is introduced for large-scale multihop wireless networks. With this algorithm, each and every active link in the network cooperatively calibrates its environment and converges to a desired link schedule for data transmissions within a time frame of multiple slots. This schedule is such that the(More)
