We are on the threshold of the explosive growth in the global Internet-of-Things (IoT) market.
Comparing with the legacy human-centric applications, machine type communication …

Indoor positioning systems have received increasing attention for supporting location-based
services in indoor environments. WiFi-based indoor localization has been attractive due to …

WLAN-based indoor location fingerprinting has been attractive owing to the advantages of
open access and high accuracy. Most fingerprinting-based systems so far rely on the …

Wireless indoor localization has attracted growing research interest in the mobile computing
community for the last decade. Various available indoor signals, including radio frequency …

Coordination of co-located wireless devices is a fundamental function/requirement for
reducing interference. However, different devices cannot directly coordinate with one …

This paper describes our design and implementation of a covert channel over LoRa physical
layer (PHY). LoRa adopts a unique modulation scheme (chirp spread spectrum (CSS)) to …

IEEE 802.15. 4 standard specifies physical layer (PHY) and medium access control (MAC)
sublayer protocols for low-rate and low-power communication applications. In this protocol …

Surveillance is a critical problem for harbor protection, border control or the security of
commercial facilities. The effective protection of vast near-coast sea surfaces and busy …

In this paper, we study the problem of uplink scheduling in wireless networks with
successive interference cancellation (SIC). With SIC, concurrent transmissions, if properly …

The hidden terminal problem is known to degrade the throughput of wireless networks due
to collisions, while the exposed terminal problem results in poor performance by wasting …
