“…Gsense [25] makes a WiFi device transmit coordination information to ZigBee devices through a customized preamble, thus to schedule their transmissions. In recent years, some methods utilize the emerging cross-technology communication (CTC) [5], [6], [26]- [28] to achieve interference management by enabling explicit coordination between heterogeneous devices [13], [14], [29]- [32]. For instance, ECC [13] makes a WiFi AP coordinate data transmissions of all the WiFi and ZigBee devices to avoid interference, thus achieves high network throughput; ECT [29] designs the network layer for CTC and lets a server schedule ZigBee transmissions; Chiron [30] designs a customized gateway to enable concurrent transmissions of WiFi and ZigBee data streams in the same frequency band to reduce the transmission delay; BiCord [32] utilizes bidirectional coordination among heterogeneous devices for efficient RF channel allocation.…”

With the rapid growth of Internet of Things, the number of heterogeneous wireless devices working in the same frequency band increases dramatically, leading to severe crosstechnology interference. To enable coexistence, researchers have proposed a large number of mechanisms to manage interference. However, existing mechanisms have severe modifications in either the physical or MAC (medium access control) layers, making them very different from the standard. In this paper, we design and implement SledZig to boost cross-technology coexistence for low-power devices through both enabling more transmission opportunities and avoiding interference. SledZig is fully compatible with the standard in both physical and MAC layers. It decreases the WiFi signal power on the channel of low-power devices while keeps the WiFi transmission power unchanged, through making constellation points on the overlapped subcarriers have the lowest power, which can be achieved by just encoding the WiFi payload. We implement SledZig on hardware testbed and evaluate its performance under different settings. Experiment results show that SledZig can effectively increase ZigBee transmissions and improve its performance over a WiFi channel under various WiFi data traffic, with as low as 6.94% WiFi throughput loss.

“…Cross-technology communication enables direct communication for heterogeneous wireless protocols and has been applying to hybrid networking [26], [27]. Early works utilize packet-level information to communicate, such as broadcasting intervals [28], signal strength [11], or channel state information [29], [30].…”

iBeacon protocol is widely deployed to provide location-based services. By receiving its BLE advertisements, nearby devices can estimate the proximity to the iBeacon or calculate indoor positions. However, the open nature of these advertisements brings vulnerability to impersonation attacks. Such attacks could lead to spam, unreliable positioning, and even security breaches. In this paper, we propose Wi-attack, revealing the feasibility of using WiFi devices to conduct impersonation attacks on iBeacon services. Different from impersonation attacks using BLE compatible hardware, Wi-attack is not restricted by broadcasting intervals and is able to impersonate multiple iBeacons at the same time. Effective attacks can be launched on iBeacon services without modifications to WiFi hardware or firmware. To enable direct communication from WiFi to BLE, we use the digital emulation technique of cross technology communication. To enhance the packet reception along with its stability, we add redundant packets to eliminate cyclic prefix error entirely. The emulation provides an iBeacon packet reception rate up to 66.2%. We conduct attacks on three iBeacon services scenarios, point deployment, multilateration, and fingerprintbased localization. The evaluation results show that Wi-attack can bring an average distance error of more than 20 meters on fingerprint-based localization using only 3 APs.

“…Many studies on CTC have been proposed to fulfill the function of translation and to support applications like channel coordination and cross-technology collaboration [22,[24][25][26][27][28][29][30][33][34][35]. Most of the existing works focus on the enabling technology of CTC, but a complete picture of the literature and the research space is missing so far.…”

The ever-developing Internet of Things (IoT) brings the prosperity of wireless sensing and control applications. In many scenarios, different wireless technologies coexist in the shared frequency medium as well as the physical space. Such wireless coexistence may lead to serious cross-technology interference (CTI) problems, e.g. channel competition, signal collision, throughput degradation. Compared with traditional methods like interference avoidance, tolerance, and concurrency mechanism, direct and timely information exchange among heterogeneous devices is therefore a fundamental requirement to ensure the usability, inter-operability, and reliability of the IoT. Under this circumstance, Cross-Technology Communication (CTC) technique thus becomes a hot topic in both academic and industrial fields, which aims at directly exchanging data among heterogeneous devices that follow different standards. This paper comprehensively summarizes the CTC techniques and reveals that the key challenge for CTC lies in the heterogeneity of IoT devices, including the incompatibility of technical standards and the asymmetry of connection capability. Based on the above finding, we present a taxonomy of the existing CTC works (packet-level CTCs and physical-level CTCs) and compare the existing CTC techniques in terms of throughput, reliability, hardware modification, and concurrency.
