We address random access networks with MAC protocols that use control packets such as RTS/CTS.

Abstract
We address random access networks with MAC protocols that use control packets such as RTS/CTS. These protocols reduce or eliminate collisions between data packets, but they typically remain prone to collisions between control and data packets. To avoid this type of collision, the data and control channels can be separated by multiplexing in the frequency domain. A small reduction in bandwidth is thus sacrificed in exchange for a reduced number of re-transmissions. This technique is investigated in conjunction with the distance-aware collision avoidance protocol (DACAP). Simulation results show that multiplexing offers some benefits to both throughput efficiency and energy consumption. ©2009 MTS.File | Dimensione | Formato | |
