Abstract

The emergence of the Internet of Things (IoT) has attracted significant attention in industrial environments. These applications necessitate meeting stringent latency and reliability standards. To address this, the IEEE 802.15.4e standard introduces a novel Medium Access Control (MAC) protocol called Time Slotted Channel Hopping (TSCH). Designing a centralized scheduling system that simultaneously achieves the required Quality of Service (QoS) is challenging due to the multi-objective optimization nature of the problem. This paper introduces a novel optimization algorithm, QoS-aware Multi-objective enhanced Differential Evolution optimization (QMDE), designed to handle the QoS metrics, such as delay and packet loss, across multiple services in heterogeneous networks while also achieving the anticipated service throughput. Through co-simulation between TSCH-SIM and Matlab, R2023a we conducted multiple simulations across diverse sensor network topologies and industrial QoS scenarios. The evaluation results illustrate that an optimal schedule generated by QMDE can effectively fulfill the QoS requirements of closed-loop supervisory control and condition monitoring industrial services in sensor networks from 16 to 100 nodes. Through extensive simulations and comparative evaluations against the Traffic-Aware Scheduling Algorithm (TASA), this study reveals the superior performance of QMDE, achieving significant enhancements in both Packet Delivery Ratio (PDR) and delay metrics.

40. Discovering and managing access to private services in collaborative sessions

Abstract

An approach that integrates service discovery with the Internet Engineering Task Force session initiation protocol to support service discovery of private services across a collaborative session is presented. Embedding the service discovery protocol within a session protocol facilitates the discovery of private services in a safe and controlled manner. Access to services is managed by defining local scopes that are shared among participants in the collaborative session. The fundamentals of the approach are presented using a simple two-party scenario and further extended by describing the approach using both central and peer-to-peer collaborative scenarios. Finally, the feasibility of the approach is demonstrated through a proof-of-concept demonstration of the sharing of Bluetooth services located in a private wireless personal area network across a telephone conversation. Index Terms--Collaborative applications, service discovery protocol, service sharing, session description protocol (SDP), session initiation protocol (SIP).

Abstract

The design and implementation of a mobile-robot system architecture is discussed. The architecture consists of a feature extraction module, an action unit and a blackboard system controller for strategic and reactive reasoning. The blackboard system consists of two hierarchical layers, namely a database to monitor the robot's environment and a set of activities for real-time navigation. It was implemented using a Cybermotion platform, 24 ultrasound sensors and two laser range finders.
