Stacking technology is an approach to improve scalability of 2D network-on-chip systems. 3D stacking technology places multiple chips vertically, while silicon chips are stacked side-by-side on a silicon interposer layer in the 2.5D stacking technology. 2.5D stacking can solve many of the 3D stacking difficulties such as thermal problem. The cores in the processing element (PE) layer must have the ability to connect together. Moreover, the connection between the processing cores and the other chips is a critical issue that should be concerned. The memory chip is one of the most important chips, integrated with the many-core chip. The network-on-chip can be extended to the interposer layer to increase the usability of the interposer layer. It is essential to have an efficient topology and deadlock-free routing algorithm to handle operations effectively and decrease delay and power consumption. In this paper, a new topology called "Balanced Mesh" and a deadlock-free routing algorithm is recommended that balances fairly the connection between different Mesh-based segments of a network. Many of interposer network topologies such as Butter Donut increase the degree of intermediate routers in the interposer layer or nodes related to other chips. Many of them cannot be easily used in the PE layer to have a uniform system. The proposed topology can be simply applied to both of many-core layer and the interposer layer to decrease delay and power consumption without any change in the degree of nodes and has lesser number of links. Our proposed topology is compared with some other topologies such as concentrated Mesh(CMesh) and ButterDount. Simulation results show that our proposed topology can improve the system efficiency with lesser number of links. Using our proposed topology in both layers achieves 13% improvement in network latency compared with using Mesh in the PE layer and ButterDonut in the interposer layer. Also, it achieves 12% improvement in power consumption.

In the research of data center network structure, routing algorithm is one of the important research fields, it is mainly to find a suitable path to transfer data information from the source node to the destination node. In this paper, multicast routing algorithm is designed for three layers of graphite structure with optimal performance. Graphite structure will be closer to practical application due to its own advantages. But the author did not design its routing algorithm. In recent years, group communication is becoming more popular. Multicast is becoming more important in group communication in current data center network. This paper introduces the construction of the three-layer graphite structure and designs the multicast routing algorithm of the three-layer graphite structure.

FOCAN: A Fog-supported smart city network architecture for management of applications in the Internet of Everything environments

JOURNAL OF PARALLEL AND DISTRIBUTED COMPUTING 2019年 132卷 274-283页

Smart city vision brings emerging heterogeneous communication technologies such as Fog Computing (FC) together to substantially reduce the latency and energy consumption of Internet of Everything (IoE) devices running various applications. The key feature that distinguishes the FC paradigm for smart cities is that it spreads communication and computing resources over the wired/wireless access network (e.g., proximate access points and base stations) to provide resource augmentation (e.g., cyberforaging) for resource- and energy-limited wired/wireless (possibly mobile) things. Motivated by these considerations, this paper presents a Fog-supported smart city network architecture called Fog Computing Architecture Network (FOCAN), a multi-tier structure in which the applications are running on things that jointly compute, route, and communicate with one another through the smart city environment. FOCAN decreases latency and improves energy provisioning and the efficiency of services among things with different capabilities. In particular, three types of communications are defined between FOCAN devices - interprimary, primary, and secondary communication-to manage applications in a way that meets the quality of service standards for the Internet of Everything. One of the main advantages of the proposed architecture is that the devices can provide the services with low energy usage and in an efficient manner. Simulation results for a selected case study demonstrate the tremendous impact of the FOCAN energy efficient solution on the communication performance of various types of things in smart cities.

As the volume of data keeps growing rapidly, more and more storage devices, servers and network devices are continuously added into data centers to store, manage and analyze the data. The industry experience indicates that, instead of a huge number of servers added at a time, the data center network also expands gradually by adding a small number of servers from time to time. As a result, how to achieve an incremental scalability is becoming a very important challenge in designing modern data center network architectures in order to maintain the topological properties unchanged when the size of data centers grows. In this paper, we propose a new type of data center network architecture named HSDC (High Scalability Data Center Network Architecture) based on the hypercube network. The HSDC is constructed by using m-port switches and 2-port servers. The fault-tolerant routing algorithm designed in this paper for HSDC can be executed on any vertex and is able to construct a path between any pair of vertices. In order to achieve an incremental scalability, we further propose three types of incomplete HSDC structures that allow gradually adding servers into the structures, while maintaining all the topological properties. The simulation experiments and performance results demonstrate that the throughput of HSDC is comparable to that of Fat-Tree, BCube and DCell. Furthermore, the analysis results indicate that HSDC strikes a good balance among diameter, bisection width, incremental scalability, cost and energy consumption in contrast to the state-of-the-art data center network architectures.

RABP: Delay/disruption tolerant network routing and buffer management algorithm based on weight

Delay/disruption tolerant network is a novel network architecture, which is mainly used to provide interoperability for many challenging networks such as wireless sensor network, ad hoc networks, and satellite networks. Delay/disruption tolerant network has extremely limited network resources, and there is typically no complete path between the source and destination. To increase the message delivery reliability, several multiple copy routing algorithms have been used. However, only a few can be applied efficiently when there is a resource constraint. In this article, a delay/disruption tolerant network routing and buffer management algorithm based on weight (RABP) is proposed. This algorithm estimates the message delay and hop count to the destination node in order to construct a weight function of the delay and hop count. A node with the least weight value will be selected as the relay node, and the algorithm implements buffer management based on the weight of the message carried by the node, for efficiently utilizing the limited network resources. Simulation results show that the RABP algorithm outperforms the Epidemic, Prophet, and Spray and wait routing algorithms in terms of the message delivery ratio, average delay, network overhead, and average hop count.

Wide-sense nonblocking and blocking converting-space-converting switching node architecture under XsVarSLOT algorithm

In this study, we evaluate the operation of the Converting-Space-Converting switching fabric architecture. The investigated switching fabric is suitable for all kinds of slot-operating switches, no matters the slots are wavelengths, time, or others. The switching fabric is evaluated in terms of the number of slots in the interstage links and the blocking probability. In the evaluation process, we used the proposed class of routing algorithms based on the functional decomposition of slots into subsets. The routing algorithm decomposes the slots in the interstage links into X subsets. The number of slots in each subset is evaluated by simulation, in order to obtain a blocking probability at the value of about 10(-8), and analytically, in case the blocking probability is reduced to 0. The proposed algorithm can reduce the required number of slots in the interstage links by almost 84% in the nonblocking switching fabrics. However;when the blocking is acceptable, the proposed routing algorithm can also reduce this number of slots, but only when the values of blocking probability are very low.

Wireless Sensor networks (WSNs) are constructed of sensors with awareness and limited energy whose topologies are set up by the signals strength being emitted. In general, the signals transmitted are usually not in uniform distribution, which lead to the living sensors having unequal residual energies. The energy holes might be emerging in WSNs since of some sensors failure. We study static WSNs with two initial energy levels. Assume that the sensors acting as base stations will never be failure and the other sensor nodes have limited energy. Adjusting hierarchical topology, using relay nodes or the density of sensors, the emergence of the energy holes would be delayed vs reduced. The separateness between data collection and data processing is also considered to balance the energy dissipation of transmission. We propose three routing algorithms named Density_Sep, SecCluHead_Sep and Relay_Sep for improving cluster head (CH) selection in legacy SEP routing protocol in WSNs. Then we briefly explained that our algorithms could be completed in polynomial time. The simulation results obtained support that our algorithms are efficient in terms of network lifetime and balancing network energy consumption.

Simultaneous wireless information and power transfer (SWIPT) transmits information and powers wireless nodes with the same radio frequency signal. It can prolong the life time of the energy constrained wireless nodes. Current works of SWIPT focus on one-hop and two-hop wireless network. In order to verify the performance of SWIPT in multi-hop energy-constrained wireless network (MECWN) where the energy harvested by the receiver node can be as an energy compensation for data forwarding, this paper concurrently considers SWIPT and routing selection in MECWN. To reduce the energy consumption, we first formulate the information and energy allocation problem of link in a forwarding path, which is dependent on the next-hop node, and solve it by an iterative allocation algorithm. A novel routing metric evaluates the energy consumption of link transmitted with or without SWIPT. The energy-aware SWIPT routing algorithm allocates the information and energy of link with allocation algorithm during path finding process. To the best of our knowledge, this is the first solution that takes account of SWIPT and routing in MECWN. Our performance studies demonstrate that our proposed algorithms can effectively exploit those node resources whose energy are not enough and significantly decrease the energy consumption.
