Cross-layer QoS-Aware Resource Allocation for IoT-Enabled Service Choreographies

Abstract

Resource allocation for distributed systems is a well-known approach to deal with quality of service requirements. However, existing approaches do not consider the effects of resource allocation at the different levels of a system, especially when considering the end-to-end behavior of distributed compositions such as service choreographies. Based on our previous research on the optimized and QoS-aware resource allocation for service choreographies and publish-subscribe brokers, we outline a novel approach that integrates the treatment of resource allocation at both levels in order to yield a more precise control over end-to-end QoS. The paper presents an early architecture and discusses some of the main challenges towards realizing the approach.

QoS‐aware IoT networks and protocols: A comprehensive survey

“…Recently proposed models such as the Pub/Sub message pattern can also achieve end‐to‐end QoS. Costa et al 108 proposed such a QoS‐aware resource allocation method based on pub/sub and broker structure. Their approach enables a firmer and more accurate grip on end‐to‐end QoS for distributed compositions that involve IoT devices and mobile services that have a tendency to become sporadically disconnected.…”
