LTE-Advanced heterogeneous networks enable a uniform broadband experience to users flexibly anywhere in the network by using a mix of large and small cells — i.e., macro, pico, femto and relay stations. In this paper, we propose a novel network coding-based for mobile content uploading, where multiple user equipments upload their own content toward the eNodeB in LTE-Advanced relay networks. Network...
With a low complexity and high successful probability, RaptorQ code is considered as an efficient solution for media transmission. However, RaptorQ code is optimal for the purpose of single layer transmission. Therefore, RaptorQ code is not suitable for dependent media transmission, where the successful decoding of the least important layer depends on the successful of the more important layer, especially...
In order to increase the efficiency of mobile video transmission in a 5G network, this paper investigates a cooperative multicast of scalable video using network coding with adaptive modulation and coding over dedicated relay-based cellular networks. Different scalable video layers prefer different protection degrees, and user equipments (UEs) in different locations experience different packet loss...
The recent research studies showed that inter-layered network coding is a promising approach to provide the unequal error protection for scalable video multicast under the channel heterogeneity. The selection of the optimal transmission distribution performed at eNB increases the system performance with the cost of time and computational complexities. In this paper, we propose an optimal transmission...
This study investigates the cooperative multicast of scalable video over dedicated relay-based cellular networks. Different layers in a scalable video tend to have different transmission quality requirements, and legacy cellular network has limitations in providing homogeneous service quality within its coverage area. The authors propose two realistic cooperative transmission schemes with a capacity...
Network coding (NC) has been exploited to minimize delay, energy per bit and to maximize throughput over lossy networks. However, applying network coding for scalable video transmission over packet-lossy networks is still an active research topic because of the challenge in trading off between rank deficiency problem and scalability of the video bitstream. Scalable video coding promises providing...
Recently, network coding and channel coding are widely applied for scalable video coding in order to achieve the reliable transmission of multimedia data. Network coding as hierarchical network coding (HNC) provides unequal erasure protection for scalable layers and addresses the process of decoding layer by layer from higher to less importance. Similar with that scheme, expanding window fountain...
This paper investigates a comparison of transmission schemes for the scalable video over multiple-input multiple-output relay networks. We consider three time-division multiple-access cooperative schemes by using embedded space time codes with various degrees of broadcasting and receiving collision. In this paper, we assume that base station and relay station are equipped two antennas and mobile stations...
