TLDR
The network selection problem for edge users is formulated as a discrete-time Markov model, and a Nash Q-learning based intelligent network access algorithm for multi-agent system, named MAQNS is proposed.Abstract:
In the heterogeneous wireless networks, it remains a significant challenge to achieve an efficient network selection strategy to satisfy the demands of a massive number of edge users and novel 5G services. In this paper, we formulate the network selection problem for edge users as a discrete-time Markov model, and propose a Nash Q-learning based intelligent network access algorithm for multi-agent system, named MAQNS. We consider the joint optimization of network selection strategies among different types of networks, aiming at maximizing the long-term performance of multi-agent system. Meanwhile, we use Analytic Hierarchy Process (AHP) and Grey Relation Analysis (GRA) to characterize the user preferences for networks. Experimental results show that comparing to the existing network selection algorithms, the proposed MAQNS has better performance in terms of system throughput, user blocking probability, average energy efficiency and average delay.read more

Clustered Virtualized Network Functions Resource Allocation based on Context-Aware Grouping in 5G Edge Networks
TL;DR: A VNF resource allocation scheme based on context-aware grouping (VNF-RACAG) technology is proposed that enables groups (based on the geographic context of users, such as location and velocity) to compute the optimal number of clusters to minimize the end-to-end delay of network services.

Scheduling and Resource Allocation in 802.11ax
TL;DR: This paper introduces a novel divide and conquer based algorithm which is optimal under the assumption that a user can be assigned to more than one resource unit (RU) which consists of one ore more subcarriers and introduces two practical algorithms which jointly splits the bandwidth into RUs and schedules users on them.
