On the Placement Delivery Array Design for Coded Caching Scheme in D2D Networks
The coded caching scheme is an efficient technique as a solution to reduce the wireless network burden during the peak timesin a Device-to-Device (D2D in short) communications. In a coded caching scheme, each file block should be divided into Fpackets. It is meaningful to design a coded caching scheme with the rate and F as small as possible, especially in the practice forD2D networ...
متن کاملPlacement Delivery Array Design for Combination Networks with Edge Caching
A major practical limitation of the Maddah-Ali-Niesen coded caching techniques is their high subpacketization level. For the simple network with a single server and multiple users, Yan et al. proposed an alternative scheme with the so-called placement delivery arrays (PDA). Such a scheme requires slightly higher transmission rates but significantly reduces the subpacketization level. In this pa...
متن کاملOn the Coded Caching Delivery Design over Wireless Networks
Coded caching scheme is a promising technique to migrate the network burden in peak hours, which attains more prominent gains than the uncoded caching. The coded caching scheme can be classified into two types, namely, the centralized and the decentralized scheme, according to whether the placement procedures are carefully designed or operated at random. However, most of the previous analysis a...
متن کاملOptimal Error Correcting Delivery Scheme for an Optimal Coded Caching Scheme with Small Buffers
Optimal delivery scheme for coded caching problems with small buffer sizes and the number of users no less than the amount of files in the server was proposed by Chen, Fan and Letaief [“Fundamental limits of caching: improved bounds for users with small buffers," IET Communications, 2016]. This scheme is referred to as the CFL scheme. In this paper, the link between the server and the users is ...
متن کاملAn Incentive-Aware Lightweight Secure Data Sharing Scheme for D2D Communication in 5G Cellular Networks
Due to the explosion of smart devices, data traffic over cellular networks has seen an exponential rise in recent years. This increase in mobile data traffic has caused an immediate need for offloading traffic from operators. Device-to-Device(D2D) communication is a promising solution to boost the capacity of cellular networks and alleviate the heavy burden on backhaul links. However, dir...
