IEEE 802.11 MAC having two methods for medium reservation. 1) virtual carrier sensing and 2) physical carrier sensing. VCS having many drawbacks in wireless ad hoc networks. PCS mechanism can replace the virtual carrier sensing in most practical applications. But choice of PCS threshold plays vital role in ad hoc networks. Choice of PCS threshold is tradeoff between the throughput and spatial reuse. In this paper we present practical experiments for to see the PCS threshold effects on network throughput.

Abstract


IEEE 802.11 MAC having two methods for medium reservation. 1) virtual carrier sensing and 2) physical carrier sensing. VCS having many drawbacks in wireless ad hoc networks. PCS mechanism can replace the virtual carrier sensing in most practical applications. But choice of PCS threshold plays vital role in ad hoc networks. Choice of PCS threshold is tradeoff between the throughput and spatial reuse. In this paper we present practical experiments for to see the PCS threshold effects on network throughput.
