Queueing Network Modeling Patterns for Reliable and Unreliable Publish/Subscribe Protocols

Mobile Internet of Things (IoT) applications are typically deployed on resource-constrained devices with intermittent network connectivity. To support the deployment of such applications, the Publish/Subscribe (pub/sub) interaction paradigm is often …

Simulation-based Queueing Models for Performance Analysis of IoT Applications

To facilitate the development of Internet of Things (IoT) applications, numerous middleware protocols and APIs have been introduced. Such applications built atop reliable or unreliable protocols and they expose different characteristics. …

QoS-Aware Resource Allocation for Mobile IoT Pub/Sub Systems

IoT applications are usually characterized by large-scale demand and the widespread use of mobile devices. Similarly, performing interaction among application and system components in a decoupled and elastic way, and enforcing Quality of Service …

Performance Modeling of the Middleware overlay Infrastructure of Mobile Things

Internet of Things (IoT) applications consist of diverse Things (sensors and devices) in terms of hardware resources. Furthermore, such applications are characterized by the Things' mobility and multiple interaction types, such as synchronous, …

Timeliness Evaluation of Intermittent Mobile Connectivity over Pub/Sub Systems

Systems deployed in mobile environments are typically characterized by intermittent connectivity and asynchronous sending/reception of data. To create effective mobile systems for such environments, it is essential to guarantee acceptable levels of …
