Many systems require frequent and regular updates of certain information. These updates have to be transferred regularly from the source(s) to a common destination. We consider scenarios in which an old packet (entire information unit) becomes completely obsolete, in the presence of a new packet. We consider transmission channels with unit storage ...

To handle the ever growing demand of resource intensive experiments distributed, network emulation tools such as Mininet and Maxinet have been proposed. They automatically allocate experimental resources. In this work, we show that resources are poorly allocated, leading to resource overloading and hence to dubious experimental results. This is why...
Cloud Radio Access Network is a promising mobile network architecture. It is based on decoupling Base Band Units (BBUs) from Radio Remote Units (RRUs) and on centralizing the baseband processing of many Radio Remote Heads (RRHs) in a BBU pool. Such architecture paves the way for many improvements in mobile networks such as increased flexibility, in...

Individuals share increasing amounts of personal multimedia data, exposing themselves (uploaders) as well as others (data subjects). Non-consensual sharing of multimedia data that depicts others raises so-called multi-party privacy conflicts (MPCs), which can have severe consequences. To limit the incidence of MPCs, a family of Precautionary mechan...

With the rapid deployment of Internet of Things (IoT) applications, video processing and streaming requirements are increasing, and edge computing is a good candidate to cope with strong latency and throughput expectations. In this paper, we consider the optimal routing, placement and scaling of IoT-based service function chains for object detectio...
Wireless Sensor Networks (WSN) are limited by the characteristics of the Radio Access Technologies (RAT) they are based on. What we refer to as Multiple Technologies Network (MTN) is a network composed of nodes able to use several RAT. The management of the RAT and routes must be handled by the nodes themselves, in a local way, with a suited commun...
Wireless communication is a key technology for the Internet of Things (IoT).Due to its open nature, the physical layer of wireless systems is a high-priority target for an adversary whose goal is to disrupt the normal behavior of the system. In particular, jamming attacks are one of the most straightforward and effective types of attacks: informati...
