The application of Unmanned Aerial Vehicles (UAVs) for securely delivering essential items during extreme conditions includes numerous challenges, particularly in ensuring identification of potential threats. To solve this challenge, we propose a strong framework that makes use of Boosting algorithms, with a particular focus on XGBoost to enhance attack classification in UAV-based delivery systems. The XGBoost model achieved an accuracy of 93%, a precision of 0.9312, a recall of 0.9311, and an F1 score of 0.9283 , which makes it a highly suitable model for security of UAVs. Explainable AI (XAI) is used to further enhance classification including SHAP and LIME to identify the most influential features, such as the barometer and battery levels. Our framework provides a comprehensive solution for secure UAV-based deliveries. The experimental results proves the effectiveness of the proposed model which shows its potential for real-life applications.

A significant share of today's Internet traffic is generated by network gaming. This kind of traffic is interesting in regard to it's market potential as well as to it's real time requirements on the network. For the consideration of game traffic in network dimensioning, traffic models are required that allow to generate a characteristic load for analytical or simulative performance evaluation of networks. In this paper we evaluate the fast action multiplayer game "Counter Strike" from a 36 hour LAN party measurement and present traffic models for client and server. The paper concludes with remarks on the use of game traffic models in simulations and on QoS metrics for an adequate evaluation of simulation results. © 2002 ACM.

There are many asynchronous communication situations for which the prevalent continuous connectivity paradigm is not needed. communication with a fair delay tolerance may inst.ad be provided by intermittent store-and-forwarding between nodes. This paper proposes a design for an open, receiver-driven broadcasting system that relies on delay-tolerant forwarding of data chunks through mobility of wireless nodes. The system provides public broadcast channels, which can be openly used for both transmission and reception. We show by simulation under benchmark mobility models that a delay-tolerant broadcast channel has both a sufficiently high throughput and reach to be interesting as a competitive alternative to the regulated wireless broadcast channel. We also present the design of, and experiences with, a proof-of-concept prototype. Copyright 2006 ACM.

Vertical handoff algorithm in heterogeneous networks to maximize system benefit

Journal of Systems engineering and Electronics 2009年第5期20卷 1124-1131页

作者： Xie Shengdong Wu Meng Computer and Software Inst. Nanjing Univ. of Information Science and Technology Nanjing 210044 P. R. China Communication and Information Engineering Inst. Nanjing Univ. of Posts and Telecommunications Nanjing 210003 P. R. China

A new vertical handoff decision algorithm is proposed to maximize the system benefit in heterogeneous wireless networks which comprise cellular networks and wireless local area networks （WLANs）. Firstly the block probability, the drop probability and the number of users in the heterogeneous networks are calculated in the channel-guard call admission method, and a function of the system benefit which is based on the new call arrival rate and the handoff call arrival rate is proposed. Then the optimal radius of WLAN is obtained by using simulation annealing （SA） method to maximize the benefit. All the nodes should handoff from cellular network to WLAN if they enter WLAN＇s scope and handoff from WLAN to cellular network if they leave the scope. Finally, the algorithm in different new call arrival rates and handoff call arrival rates is analyzed and results show that it can achieve good effects.

A hybrid abstraction of a full system simulation platform can provide flexible hardware-and-software co-verification and co-simulation in early stage of system-on-a-chip development. Being a hybrid abstraction for the simulated system, it has the advantage of faster simulation speed;however, its lack of timing information and no performance-metric synchronization mechanism among the different abstraction levels of the simulation models present troubles in doing performance analysis. To facilitate performance evaluations for hybrid abstraction simulation systems, in this paper, we propose a synchronization profiler to enable cross-abstraction level performance analysis and at the same time retain the fast simulation advantage. This approach allows a design engineer to evaluate not only the interactions between an application and its accelerated hardware but also the corresponding device drivers as well as the OS kernel. ©2010 IEEE.

Hardware-and-software full system co-verification and co-simulation in the early stage of SoC development, i.e., before HDL code synthesis, is usually a big challenge for design engineers. In this paper, we propose a QEMU-based full system simulation framework to tackle the problem faced with the design of an embedded multi-view 3D GPU (graphic processing unit). Through the framework, we are able to extensively explore the multi-view GPU architecture, and at the same time software designers can develop and debug the associated device drivers and graphics applications by simulating the GPU design in full system operation. This approach greatly improves the ESL design process and shortens the development time for the complex multi-view GPU system. ©2010 IEEE.

Podcasting has become a very popular and successful Internet service in a short time. This success illustrates the interest for participatory broadcasting, but podcasting is alas only available with fixed infrastructure support to retrieve publicized episodes. We aim at releasing this limitation and present herein a podcasting system architecture based on opportunistic wireless networking that allows us to extend podcasting to ad hoc domains. The design is explained and presented together with a prototype implementation running on hand-held devices. We analyze different fundamental design tradeoffs based on measurements.

Multi-constraint quality of service routing algorithm for dynamic topology networks

Journal of Systems engineering and Electronics 2008年第1期19卷 58-64页

作者： Wang Ping Chen Bingcai Gu Xuemai Liu Gongliang Communication Research Center Harbin Inst. of Technology Harbin 150001 P. R. China School of Computer Science and Technology Harbin Engineering Univ. Harbin 150001 P. R. China

An adaptive multi-QoS routing algorithm called AMQRA is proposed for dynamic topology networks, such as satellite networks and Ad-hoc networks. The AMQRA is a distributed and mobile-agents-based routing algorithm, which combines ant quantity system （AQS） with ant colony optimization （ACO） that is used in AntNet routing algorithm. In dynamic topology networks, the AMQRA achieves timely optimization for concave metric QoS constraint and fast convergence. The proposed routing algorithm is simulated in Iridium satellite constellation on OPNET. The results show that AMQRA not only outperforms the AntNet in convergence rate in dynamic topology networks but also can optimize concave metric QoS constraint and reasonably allot bandwidth to the load to avoid networks congestion.
