Service Level Agreements for Communication Networks: A Survey, 2019

Therefore, Service Level Agreements (SLAs) are essential and play a key role to manage the provided services among the network entities. This survey identifies the state of the art covering concepts, approaches and open problems of the SLAs establishment, deployment and management. This paper is organised in a way that the reader can access a variety of proposed SLA methods and models addressed and provides an overview of the SLA actors and elements. It also describes SLAs' characteristics and objectives. SLAs' existing methodologies are explained and categorised followed by the Service Quality Categories (SQD) and Quality-Based Service Descriptions (QSD). SLA modelling and architectures are discussed, and open research problems and future research directions are introduced. The establishment of a reliable, safe and QoE-aware computer networking needs a group of services that goes beyond pure networking services. Therefore, within the paper this broader set of services are taken into consideration and for each Service Level Objective (SLO) the related services domains will be indicated. The purpose of this survey is to identify existing research gaps in utilising SLA elements to develop a generic methodology, considering all quality parameters beyond the Quality of Service (QoS) and what must or can be taken into account to define, establish and deploy an SLA. This study is still an active research on how to specify and develop an SLA to achieve the win-win agreements among all actors.
An adaptive fuzzy handover triggering approach for Long-Term Evolution network
Expert Systems, 2015

The existing handover triggering scheme for LTE is not flexible enough to incorporate new performance metrics, and it introduces handover latency. There are studies on non-conventional handoff algorithms for LTE applications, for instance, the fuzzy logic approach. However, the fuzzy logic approach needs regular manual tuning to constantly produce optimal output. In this paper, we address this issue by proposing an adaptive fuzzy logic-based handoff decision algorithm, which can cope with environmental changes and improve efficiency by reducing human intervention. Performance results show that the proposed algorithm can reduce unnecessary handovers by about 20% compared with the fuzzy logic and conventional LTE handover triggering scheme, leading to reduced packet loss rates.

The suggested access router effectively combines both WiMAX and LR-WPAN technologies in a same device. The main motivation to propose this integration is to deploy Internet of Things (IoT) applications and services in wide area networks. Using WiMAX as backhaul service, the Internet connection can be provided for dispersed mobile LR-WPAN users over a wide area. Moreover, it enables to access all collected data in the local LR-WPAN coverage area -which is named as Senspot in this paper -by third-party clients through the Internet. Furthermore, an analytic model has been developed for the integrated network to evaluate the system's performance. Theoretical results on blocking probability of new and handover calls from WiMAX subscribers, as well as new connections from LR-WPAN Senspots in a cell of WiMAX have been investigated in terms of call/connection rates and number of allocated channels.
