A Fairness Load Balancing Algorithm in HWN Using a Multihoming Strategy

Abstract

Due to the growth of the number of intelligent devices and the
broadband requirements, between others technical requirements, of the new
applications, suppose a new challenge in planning, maintenance and resource
allocation in mobile networks for the telecommunication operators. Service
providers must ensure a quality of service for users in a new environment
based in Heterogeneous Wireless Networks (HWN). A good way to achieve
this goal is to prevent the quantity of services of each mobile users being
connected to the same access networks and therefore reducing the possibility
of overloading it. This paper presents a load balancing optimization scheme
that enables operators to make decisions about re-allocation of each of the
services in different access networks, keeping the required Quality of Service
(QoS). In this paper, we propose 1) a mathematical model addressed as a
fairness resource allocation in order to obtain a global load balancing, and 2) a
two-step algorithm based on the anchor-adjustment heuristic to solve it. Our
algorithm contribute to unload the network with maximum load while at the
same time, the other networks are balanced. As a result, we show that our
algorithm finds (near)-optimal solutions while keeps low complexity.
