By taking advantage of fog-computing, our proposed strategy enables BSs to combine and process signals received from diverse paths, which can significantly increase the transmission efficiency of the backhaul network. We first model an F-RAN-enabled network and three existing backhauling strategies, namely, direct transmission, decode and forward, and cloud-RAN. We then analyze and compare the performance of these strategies. The numerical results show that our proposed strategy provides the highest throughput for cell edge users while maintaining the same performance in most of the other areas. Moreover, for dense small-cell networks with poor backhaul channels, F-RAN outperforms all other strategies.}, journal={IEEE ACCESS}, author={Li, Zifan and Sichitiu, Mihail L. and Qiu, Xuesong}, year={2019}, pages={14150–14161} }
 @inproceedings{li_thuente_2017, title={Extensions and improvements of jump-stay rendezvous algorithms for cognitive radios}, DOI={10.1109/mownet.2017.8045952}, abstractNote={Modular-based channel hopping (CH) rendezvous algorithms can provide guaranteed rendezvous for Cognitive Radio Networks (CRNs) without time synchronization or Common Control Channels (i.e., blind rendezvous). The Enhanced Jump-Stay (EJS) scheme [1] has now been recognized as arguably the best in terms of Maximum-Time-To-Rendezvous (MTTR) and bounds for the Expected-Time-To-Rendezvous (ETTR) for users with a different number of channels (asymmetric). In [2], we developed a probabilistic channel detecting jamming attacks that dramatically decreased the rendezvous success rates of EJS and developed the Random Enhanced Jump Stay (REJS) CH rendezvous algorithm that largely mitigated those jamming attack. Here we provide extensions of EJS and REJS and provide guidelines when they should be used. The focus in [2] was jamming mitigation but here we carefully analyze the performance of several new algorithms while still guaranteeing bounded MTTR and improved the ETTR over EJS. In fact, it appears EJS should seldom be used. We show our jump-stay extensions are better than EJS with significant decreases in the average TTR.}, booktitle={International conference on selected topics in mobile and wireless}, author={Li, Z.
