This project contains the base code for the E-Fi mechanism, a research project from Northeastern University in the Genesys Lab in collaboration with the Mathworks inc. The formal paper is published in the IEEE Transactions of Mobile Computing (TMC) [1]. E-Fi allows Wi-Fi devices to coexist with LTE on the same band without requiring any changes on the LTE and Wi-Fi Physical Layer (unlike Listen-Before-Talk or CSAT) by extending its capabilities with the WiFi Direct Standard, which allows for a multi-hop communication, and scheduling its transmissions within Almost Blank Subframes (ABS) (an Inter-cell Interference coordination mechanism present in LTE Release 10). The E-Fi mechanism can be summarized into the following steps:
1. Packet Success Rate (PSR) evaluation based on received power (Prx) and Signal-to-Noise Ratio (SINR).
2. Node Pre-categorization (Relay, Wi-Fi Direct Client or Regular Client).
3. Device discovery and PSR exchange.
4. Node Grouping and ABS distribution.
