LoRaWAN is a media access control (MAC) protocol for wide area networks. It designed to allow low-powered devices communicate with Internet-connected applications over long-range wireless connections. The targeted dense deployment will inevitably cause shortage of radio resources. Hence, autonomous and lightweight resource management crucial offer ultra-long battery lifetime LoRa devices. One the most promising solutions such challenge use artificial intelligence. This enable innovative...

Energy efficiency is a major driving factor in the Internet of Things (IoT). In this context, an IoT approach based on Information-Centric Networking (ICN) offers prospects for low energy consumption. Indeed, ICN can provide local in-network content caching so that relevant remains available at any time while devices are deep-sleep mode most time. paper, we evaluate NDN enhanced with CoCa, simple side protocol designed to exploit names together smart interplay between cooperative and...

Despite their widespread adoption, cellular networks face growing vulnerabilities due to inherent complexity and the integration of advanced technologies. One major threats in this landscape is Voice over IP (VoIP) GSM gateways, known as SIMBox devices. These devices use multiple SIM cards route VoIP traffic through networks, enabling international bypass fraud with losses up $3.11 billion annually. Beyond financial impact, activity degrades network performance, threatens national security,...

Scalability is one of the toughest challenges in ad hoc networking. Recent work outlines theoretical bounds on how well routing protocols could scale this environment. However, none popular solutions really scales to large networks, by coming close enough these bounds. In paper, we study case link state and OLSR, strongest candidates for standardization. We analyze are not reached case, much scalability enhanced with use Fish eye techniques addition framework. show that enhancement, reached.

In the IoT, trade-off between content availability and energy efficiency plays a crucial role. The standard approach to in IoT combines low-power radios, network protocols letting devices sleep most of time, centralized caching content, either at designated proxy or cloud via an uplink, which maintains while sleep. However, this is not possible number scenarios, where gateway/proxy unavailable time. paper, we propose leveraging distributed for based on information-centric networking...
