PRACTICAL ANALYSIS OF COMMON RADIO RESOURCE MANAGEMENT SCHEME IN HETEROGENEOUS WIRELESS NETWORKS

Abstract

Mobile communication has become an essential part of the human life. On the other hand, there is a increasing in
the developed technologies. So, people are facing lots of problems for best utilizations of the operation of existing radio
access technologies (RATs) that they may have. Radio Resource Management (RRM) refers to a mechanisms that are
responsible for best utilization of Radio Resource Units (RRUs) within a Radio Access Technology (RAT) to provide
services with an acceptable level of Quality of Service (QoS). A major issue of the heterogeneous network is the Radio
Resource Management (RRM) strategy. None of the RRM scheme is suitable for the heterogeneous network, because each
RRM strategy only considers the situation of one and only particular RAT. The Common Radio Resource Management
strategy, also known as Joint Radio Resource Management (JRRM), is used to coordinate RRU utilization among a number
of RATs in an optimized way. CRRM is used to increase the selection of the suitable RAT in the heterogeneous wireless
networks (HWN). Selection of the suitable radio access technology maximizes the performance of heterogeneous wireless
network and its Quality of Service (QoS). CRRM is deployed in order to collectively manage radio resources among
different Radio Access technologies (RATs) in an optimized way. This paper can bring significant benefits in the
heterogeneous network, such as improving throughput and packet delivery ratio, reduction of delay and jitter (packet delay
variance).
