The network-on-chip(NoC) has been effectively developed for resolving the problem of communication on-chip. Its topology and routing algorithm that have significant impacts on network performance are currently research focuses. Since low power is a critical issue to be focused on, Mesh-of-Tree(MoT) topology is more ideal. But some routers in Mo T may carry out heavy communication tasks, which means these routers consume more power and easily become hotspots. In this paper, we proposed a simplified Mesh-of-Tree(SMoT) topology based on Mo T in order to weaken this phenomenon and reduce the power consumption. We also proposed a congestion-aware routing algorithm for SMo T, considering both network load and shortest path between cores, making the communication spread to the entire network through adjusting the direction of data forwarding to decrease the network latency. By applying our proposed approach, compared with Mo T, experiment result shows the power consumption in network can be reduced by 5.39%–23.3%, the reduction in network latency is 4.23%–27.28%.

routing algorithm has a decisive influence on routing quality, and routing quality has a direct impact on network performance. For FANETs, the highly dynamically changing topology poses a challenge to the design of routing algorithms. The paper studies the characteristics of FANETs, and uses a CHNN to search for FANETs routing to form CHNNR. Using NS3 as a simulation tool, a highly dynamic simulation scheme in the background of the network topology of the air flight platform was designed, making the simulation scene closer to the dynamic performance of the FANETs highly dynamic mobile node. By comparing parameters such as network delay, normalized network throughput, routing load and data transmission success rate, the performance of CHNNR and passive routing algorithms is analyzed and compared. The simulation results show that the comprehensive performance of CHNNR is better than other passive routing algorithms, and it is more suitable for FANETs networks where nodes move at a high speed and the network topology changes frequently, and lay the foundation for the next research.

The communication efficiency represents one of the key aspects in the future smart grid. Indeed, as the power distribution grid is being extended to fulfill increasing power demand population, recent advanced wireless communication standards and updates in the architecture of the distribution network have been introduced to upgrade the efficiency of data transmission and quality of service, enabling potential diversification of the power grid network depending on the operating environment. In this paper, we focus on wireless communications in the distribution trunk of the smart grid and propose an improved routing algorithm for wireless path selection to provide higher efficiency and reliability of communication. Comparison with existing schemes outline the potential benefits of introducing the proposing methodology.

Most of the existing routing algorithms are based on two dimension, and the results can't be directly applied to the three dimensional wireless sensor networks, the Space Angle Based Energy-Aware routing algorithm in three dimensional wireless sensor networks is designed in this paper. Firstly, the Iterative Split Clustering algorithm for dividing the network nodes is proposed. Secondly, we design the Space Angel Energy routing algorithm to transfer data within the clusters and between the clusters respectively, achieving the goal of less energy consumption and extending the network lifetime. We simulate and implement the algorithm and evaluate the performance based on topologies with different scales, and get a conclusion that by comparing with the typical algorithm, the routing algorithms proposed in this paper are able to reduce the network energy consumption effectively and extend the network lifetime.

Improved Compact routing Schemes for Random Interconnects

INTERNATIONAL JOURNAL OF DISTRIBUTED SYSTEMS AND TECHNOLOGIES 2020年第3期11卷 89-109页

Random topology has been an increasingly favorable approach for designing interconnection networks, as it can provide a combination of low latency and incremental network growth that could not be provided by the traditional rigid topologies. However, the common shortest-path routing in a random interconnect poses a scalability problem, for it requires global network info to make routing decisions and so, the routing table size (RTS) can be very large. Therefore, this manuscript would aim to revisit the well-known research area of landmark-based compact routing and to improve the universal routing schemes for the specific case of random interconnects. It would propose new landmark-based compact routing schemes, using 2 heuristic techniques to select landmarks that are evenly spaced, which would reduce the RTS in the well-known Thorup and Zwick's scheme by up to 18% and produce a shorter average path length.

In this paper, we propose an efficient routing algorithm based on AODV for the Mobile Hybrid Wireless Networks (MHWNs), which consists of the mobile ad hoc networks (MANETs) and an infrastructure wireless networks (such as cellular networks). In MANETs, the performance of the networks has been greatly challenged by the mobility from nodes and link state changes, while the link in cellular networks remains stable link with the mobile stations. This algorithm for routing construction takes advantage of the features of MHWNs, such as hybrid radio channels and nodes heterogeneity, to accomplish the bi-direction routing discovery on demand. Our results show that the performance of MHWNs is improved in the time and overhead for route path discovery process the under our bi-direction route algorithm.

Semantic Privacy Inference Preservation algorithm for Indoor Trajectory

引用

INTERNATIONAL JOURNAL OF ADVANCED COMPUTER SCIENCE AND APPLICATIONS 2023年第7期14卷 868-876页

作者： Alamri, Abdullah Univ Jeddah Coll Comp Sci & Engn Jeddah Saudi Arabia

Indoor location services have become an increasingly important part of our everyday lives in recent years. Despite the numerous benefits these services offer, serious concerns have arisen about the privacy of users' locations. Adversaries can monitor user-requested locations in order to obtain sensitive information such as shopping patterns. Many users of indoor spaces want their movements and locations to be kept private so as not to reveal their visit to a particular zone inside buildings. Research on semantic indoor trajectory-based human movement data has primarily focused on finding routes without taking into account the protection of privacy. Hence, the servers on which trajectory data is stored are not completely secure. In this paper, we propose a semantic privacy inference preservation algorithm for an indoor trajectory that can issue pathfinding and navigation instructions while achieving good privacy protection of moving entities by generating ambiguous trajectory. The simulation of the proposed semantic indoor privacy algorithm was implemented in MATLAB.
