Physical carrier sensing is an effective mechanism of medium access control (MAC) protocols to reduce collisions in wireless networks, and the size of the carrier sensing range has a great impact on the system performance. Previous studies have shown that the MAC layer overhead plays an important role in determining the optimal carrier sensing range. However, variable transmission ranges and receiver sensitivities for different channel rates and the impact of multihop forwarding have been… CONTINUE READING
