Energy efficiency of slotted LoRaWAN communication with out-of-band synchronization
Luca Beltramelli, Aamir Mahmood, Patrik Österberg +3
Although the idea of using wireless links for covering large areas is not new, the advent of LPWANs has recently started changing the game. Simple, robust, narrowband modulation sc…
Synchronous LoRa Communication by Exploiting Large-Area Out-of-Band Synchronization
Luca Beltramelli, Aamir Mahmood, Paolo Ferrari +3
Many new narrowband low-power wide-area networks (LPWANs) (e.g., LoRaWAN, Sigfox) have opted to use pure ALOHA-like access for its reduced control overhead and asynchronous transmi…
LoRa beyond ALOHA: An Investigation of Alternative Random Access Protocols
Luca Beltramelli, Aamir Mahmood, Patrik Österberg +1
We present a stochastic geometry-based model to investigate alternative medium access choices for LoRaWAN---a widely adopted low-power wide-area networking (LPWAN) technology for t…
Security of the Internet of Things: Vulnerabilities, Attacks and Countermeasures
Ismail Butun, Patrik Österberg, Houbing Song
Wireless Sensor Networks (WSNs) constitute one of the most promising third-millennium technologies and have a wide range of applications in our surrounding environment. The reason…
Security Implications of Fog Computing on the Internet of Things
Ismail Butun, Alparslan Sari, Patrik Österberg
Recently, the use of IoT devices and sensors has been rapidly increased which also caused data generation (information and logs), bandwidth usage, and related phenomena to be incre…
