Clustered CDMA ad hoc networks without closed-loop power control
Aamir Hasan, K. Yang, Jeffrey G. Andrews · 2004
This paper develops a system design for clustered wireless ad hoc networks, combining CSMA and CDMA to enable spatial reuse and simultaneous transmissions. Typically, CDMA networks require fine-tuned power control, but here that requirement is eliminated through a combination of open loop power control, user ordering, and successive interference cancellation (SIC). A network topology with high network awareness via a broadcast CSMA channel is developed. The resulting system increases network throughput and overcomes existing problems with IEEE 802.11.
