Abstract
Dense carrier sensing wireless networks are important scenarios to enable ubiquitous mobile Internet access. In this work, we study user experience from the end-to-end performance of dense p-persistent CSMA networks that suffers from operation interference among many non-coordinated APs. Results show that in dense networks, the effective coverage of APs shrinks and most STAs don't receive satisfactory services which renders the network useless. We find that a dense network with multiple non-cooperative APs does not always result in lower latency. The RTS/CTS handshake also does not guarantee better latency than the basic access method in dense networks. For end-to-end throughput and end-to-end drop rate, results show that a dense network with many non-coordinated STAs has poor performance compared to that with few due to high collision, contention, and outage. On the other hand, a dense network covered by multiple APs offers better end-to-end performance compared to one covered by few. The RTS/CTS handshake also brings similar performance enhancement. Appropriate optimization associated with application scenarios are useful.
