Future Mobile Communications: LTE Optimization and Mobile Network Virtualization
Providing QoS while optimizing the LTE network in a cost efficient manner is very challenging. Thus, radio scheduling is one of the most important functions in mobile broadband networks. The design of a mobile network radio scheduler holds several objectives that need to be satisfied, for example: the scheduler needs to maximize the radio performance by efficiently distributing the limited radi...
متن کاملFuture Mobile Communications - LTE Optimization and Mobile Network Virtualization
This paper presents the concepts of network virtualization, focusing specifically on wireless virtualization of the LTE mobile communication system. A novel wireless virtualization framework is proposed and developed, which allows mobile network operators to share the wireless spectrum, as well as, the infrastructure (i.e., hardwares equipment). The framework targets the concepts of wireless vi...
متن کاملIntelligent Network Selection for Vertical Handover Optimization in LTE-Advanced
Vertical handover decision (VHD) is a complex strategy in heterogeneous wireless networks because of its significance on network application and performance. The mechanism adopted for the vertical handover utilizes the “break – before – make” phenomenon. However, issue of network availability and the choice of the best available network may be an illusion as the mechanism is subjected to many d...
متن کاملDimensioning of LTE Network
Long Term Evolution (LTE) is 3GPP enhancement to the current cellular system in use. The purpose of developing this system is to keep 3GPP systems competent enough for decades to come. LTE is designed to have wider channels up to 20MHz, with low latency and packet optimized radio access technology. The peak data rate envisaged for LTE is 100 Mbps in downlink and 50 Mbps in the uplink. With OFDM...
متن کاملLte Cellular Network
In this paper we have studied downlink packet scheduling algorithms proposed for LTE cellular networks. The study emphasize on three most promising scheduling algorithms such as: FLS, EXP rule and LOG rule. The performance of these three algorithms is conducted over video traffic in a vehicular environment using LTE-Sim simulator. The simulation was setup with varying number of users from 10 60...
