Survey of soft computing techniques for joint radio resource management

Ever changing requirements of the mobile devices has posed significant challenges on existing cellular network systems. The Next Generation Wireless Networks (NGWN) will be heterogeneous which will have different Radio Access Technologies (RATs) operating together. Radio Resource Management (RRM) is one of the key challenges in NGWN. Joint Radio Resource Management (JRRM) is one of the RRM technique plays instrumental role in ensuring the desired Quality of Service (QoS) to the users working on different applications which are having the diversified nature of QoS requirements to be fulfilled by the wireless networks. Soft computing is one promising field which is strongly believed to enhance the capability of the existing methods for JRRM. The objective of this paper is to bring out the best features of soft computing techniques for JRRM in NGWN to enhance capability of existing methods, which integrates the different RRM strategies using soft computing techniques for NGWN and observe how JRRM would properly work together with soft computing techniques in heterogeneous scenario to perform better than the existing techniques.
