Analysis of the RTS/CTS Multiple Access Scheme with Capture Effect
Chin Keong Ho, Jean‐Paul M. G. Linnartz · 2006
The Request-to-Send (RTS) / Clear-to-Send (CTS) scheme uses a four-way handshake to ensure proper spatial and temporal reservation of the multiple-access wireless LAN channel. By considering the (interdependence of) successive capture probabilities for a cycle of an RTS, CTS, data packet and acknowledgement, we analyze the throughput of the RTS/CTS scheme in a new mathematical framework. We also propose closed-form bounds which are useful for rate optimization.
