This paper presents MIMO/CON, a PHY/MAC cross-layer design for multiuser MIMO wireless networks that delivers throughput scalable to many users. MIMO/CON supports concurrent channel access from uncoordinated and loosely synchronized users. This new capability allows a multi-antenna MIMO access point (AP) to fully realize its MIMO capacity gain. MIMO/CON draws insight from compressive sensing to carry...
In this work, we present an experimental study, in which we deploy a 14-node 802.15.4-based sensor network in our department building. Using the k-nearest-neighbor (KNN) method to the estimation of location, we implement an RSSI-signature-based localization system on top of the network.
