A Survey of Intelligent approach for Handoff Decision making for Long Term Evolution Heterogeneous Network

The development of high density and highly dynamic heterogeneous wireless network (HWN) is anticipated to give an wide range of application to end client. This wide range of application presents diverse contextual criteria prerequisites. In future generation high speed, dynamic, and dense mobile network, the end clients will have wide range of radio access technology (RAT) for selection to transmit and receive information. In order to achieve moderate cost of end user, high data rate and better Quality of service (QoS), end client can select wireless local area network (WLAN), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications System (UMTS) respectively. Therefore, seamless mobility must be appropriately figured out to accomplish the objective of the next generation wireless access frameworks and offer clients with the comfort of consistent moving between HWNs. To accomplish this objective, the aid of handovers (HO) of multi-rate traffics in versatile and dynamic mobility management is essential. Thus, this work aims to conduct survey of an intelligent approach for handoff decision mechanism for LTE heterogeneous multi-service wireless networks considering multiple parameters like signaling overhead, network communication cost, location and mobility management, QoS, and connection time, user quality of experience on HWN for HO decision making.
