“…Available radio resources of coupled networks will be jointly managed. We hence adopt the CRRM architecture introduced by the 3rd Generation Partnership Project (3GPP) [3] and further used in [4][5][6][7][8][9][10][11]. CRRM is defined as a platform to gather information from the Base Stations (BS) of different RATs, and to control the resource allocation of all BSs to optimize the overall system performance.…”

Abstract-The paper aims at improving the load balancing algorithm in wireless packet cellular networks and particularly in coordinated heterogeneous wireless packet networks. Our main contributions are two-fold. First, we introduce a new approach to compute the network load metric based on the radio link quality and scheduling information, which can be applied to any wireless packet system. This load metric hides the radio resources heterogeneity of different access technologies from the load balancer. Secondly, we propose a new practical load balancing algorithm which provides a more efficient way to manage the scarce radio resources. The proposed approach has been compared with different existing schemes and the results show the superiority of the proposed solution.

“…However, they assume corporate customers with infrastructure-based and stable networks. Finally, the architecture proposed by [5] supports integration of tightlyas well as loosely-coupled WLANs, but it focuses essentially on the connection between structured WLANs to the core cellular network. The protocol proposed in our paper is targeted at integrating administratively independent and mobile networks.…”

Current mobile devices support multiple network technologies and network composition via such devices can enable service provisioning across heterogeneous networks. One of the key challenges for realizing this view is inter-domain routing. Indeed, given the diversity of involved network technologies and infrastructures, a flexible routing protocol that takes into account their quality properties and dynamics is an important requirement. In this paper, we present a flexible quality-aware routing protocol for infrastructure-less B3G environments that enables discovery of routes with optimal bandwidth, delay or cost according to the preference of each client. The protocol is based on the Optimized LinkState Routing (OLSR) protocol and is designed to enable computation of quality-aware routes in multi-network environments. We detail the protocol, discuss its deployment and provide experimental results.

“…In the VHO process, decisions can be very interesting, since this type of HO can be based on a wide set of parameters, and/or operator policies/strategies. In literature, different authors address this issue, using different parameters to trigger VHO: in [11] the service type, network conditions, operator policies, user preferences, and signal level are taken into account for a VHO decision; authors in [12] use the service financial cost, signal level, QoS, user velocity, and link capacity; similarly, in [13], the service financial cost, signal level, and throughput are taken. The fuzzy control approach is also considered in [14], which is based on signal level, service financial cost, and bandwidth.…”

A Cost Function Model for CRRM over Heterogeneous Wireless Networks

Heterogeneous cellular networks performance is usually analysed by taking several Key Performance Indicators (KPIs) into account, their proper balance being required in order to guarantee a desired Quality of Service (QoS). An approach to simplify and integrate a set of KPIs into a single one is presented, by using the proposed Cost Function model that includes these KPIs, providing a single evaluation parameter as output, and reflecting network conditions and Common Radio Resource Management (CRRM) strategies performance. This paper proposes a Cost Function that enables the implementation of different CRRM algorithms and policies, by manipulating KPIs according to user's or operator's perspectives, allowing for a better QoS. Results show that different policies can in fact be established, with a different impact on the network, e.g., with median values ranging by a factor higher than two.
