This paper presents a novel parallel quasi-cyclic low-density parity-check (QC-LDPC) encoding algorithm with low complexity, which is compatible with the 5th generation (5G) new radio (NR). Basing on the algorithm, we propose a high area-efficient parallel encoder with compatible architecture. The proposed encoder has the advantages of parallel encoding and pipelined operations. Furthermore, it is designed as a configurable encoding structure, which is fully compatible with different base graphs of 5G LDPC. Thus, the encoder architecture has flexible adaptability for various 5G LDPC codes. The proposed encoder was synthesized in a 65 nm CMOS technology. According to the encoder architecture, we implemented nine encoders for distributed lifting sizes of two base graphs. The eperimental results show that the encoder has high performance and significant area-efficiency, which is better than related prior art. This work includes a whole set of encoding algorithm and the compatible encoders, which are fully compatible with different base graphs of 5G LDPC codes. Therefore, it has more flexible adaptability for various 5G application scenarios.

“…However, the requirements of services and applications are dynamically changing, and the complexity of network parameters remains an open issue for the generation, deletion, and link management of virtualized network functions. Service function chaining (SFC) is an orchestration mechanism that creates service chains and forwards data flows through these service chains [11]. NFV-SFC is an ordered collection of virtual network functions (VNFs), where user data is passed through multiple VNFs in a specified strategy, enabling on-demand processing of network resources.…”

The high proportion of new energy sources integration causes issues such as load imbalance and high complexity in resource management. Low resource utilization has emerged in the power communication network. It is urgent to provide unified scheduling and on-demand resource allocation. Hence, the dynamic resource orchestration mechanism for a power communication network is studied based on NFV-SFC. First, the resource orchestration architecture based on NFV-SFC is constructed to complete the scheduling of virtual network functions. An NFV-SFC-based dynamic resource orchestration model is established to evaluate the performance of dynamic resource configuration and a dynamic resource orchestration mechanism based on a simulated annealing algorithm is proposed. Numerical results show the algorithm's effectiveness.

To evaluate the steady-state availability of heterogeneous edge computing-enabled wireless sensor networks (HECWSNs) with malware infections, we first propose a Stackelberg attack-defence game to predict the optimal strategies of malware and intrusion detection systems (IDSs) deployed in heterogeneous sensor nodes (HSNs). Next, we present a new malware infection model—heterogeneous susceptible-threatened-active-recovered-dead (HSTARD) based on epidemic theory. Then, considering the heterogeneity of sink sensor nodes and common sensor nodes and the malware attack correlation, we derive the state transition probability matrix of an HSN based on a semi-Markov process (SMP), as well as the steady-state availability of an HSN. Furthermore, based on a data flow analysis of HSNs, we deduce the steady-state availability of HECWSNs with various topologies, including the star topology, cluster topology, and mesh topology. Finally, numerical analyses illustrate the influence of the IDS parameters on the optimal infection probability of malware and reveal the effect of multiple factors on the steady-state availability of HSNs, including the initial infection rate, the infection change rate, and the malware attack correlation. In addition, we present data analyses of the steady-state availability of HECWSNs with various topologies, including the star topology, cluster topology, and mesh topology, which provide a theoretical basis for the design, deployment, and maintenance of high-availability HECWSNs.
