The increasing population has led to a disruption of health status due to the waste management system. Waste management in the form of smart cities has created a kind of concern and is an activity that can provide environmental, health, and social benefits. Waste management is a technique to prevent the accumulation of waste. If it is not managed properly, it will lead to a series of unhealthy and unsanitary conditions in the city. Therefore, to prevent and reduce waste it is needed an intelligent waste management system and one of the newest platforms in this basin is the Internet of Things (IoT) platform. The IoT has revolutionized the waste management system. Different governments are trying to meet this great challenge by creating different IoTbased waste management systems and for this purpose different technologies and sensors such as Bluetooth ultrasonic sensors, RFID tags, etc. are used in their architectures to receive real-time information. Due to the benefit of the use of the IoT in waste management, this article analyzes some of the most recent methods for managing and reducing waste based on the Internet of Things, as well as evaluating various barriers, challenges, and solutions. Also, the characteristics of each method and the advantages and disadvantages are stated. © 2022 IEEE.

In-network data aggregation is one of the most important issues for achieving energy-efficiency in wireless sensor networks since sensor nodes in the surrounding region of an event may generate redundant sensed data. The redundant sensed data should be aggregated before being delivered to the sink to reduce energy consumption. Which node should be selected as a Data Aggregation Node (DAN) for achieving the best energy efficiency is a difficult issue. To address this issue, this letter proposes a scheme to select a DAN for achieving energy-efficiency in an event region. The proposed scheme uses an analytical model to select the sensor node that has the lowest total energy consumption for gathering data from sensor nodes and for forwarding aggregated data to a sink, as a DAN. Analysis and simulation results show that the proposed scheme is superior to other schemes. Copyright © 2010 The Institute of Electronics, Information and Communication Engineers.

Customer classification and prioritization are commonly utilized in applications to provide queue preferential service. Their fairness aspects, which are inherent to any preferential system and highly important to customers, have not been fully studied and quantified to date. We use the recently proposed Resource Allocation Queueing Fairness Measure (RAQFM), and a newly introduced metric called class discrimination, which is based on RAQFM, to analyze such systems and derive their relative fairness values as well as the discrimination experienced by the various classes. Specifically, we study two practices, commonly used in public facilities as well as in computer systems: class prioritization and dedication of resources to classes. © 2008 ICST ISBN.

In cognitive radio (CR) systems, secondary users (SUs) have to detect channel periodically during their data transmission to decide whether the channel is idle in order to avoid unacceptable interferences to primary users (Pus). With the traditional spectrum sensing method, all secondary users must carry out the detection process on the spectrum band before data transmission. The longer the detection time, the lower the channel efficiency is. In this paper, we explore the issue on detection method selection that aims at improving the channel efficiency. We propose a continuous spectrum sensing method with which the secondary users can detect the spectrum even if they are transmitting data to each other. This method not only improves the channel efficiency, but also senses the primary signal quickly. © 2012 IEEE.

Recognition of wobbling and nutating cone-shaped targets is a major challenge in space target recognition area. In this paper, we develop a signal model of multiple scattering centers on the wobbling and nutating cone-shaped targets, analyze the micro-Doppler characteristics of their echo. It is concluded that the micro-Doppler features have remarkable differences due to their different micro-motion. Therefore, we apply viterbi algorithm to extract the micro-Doppler and micro-motion parameters, the simulation results demonstrate that the wobbling and nutating cone-shaped targets can be recognized effectively in this way. ©2010 IEEE.

The security of Federated Learning(FL)/Distributed Machine Learning(DML)is gravely threatened by data poisoning attacks,which destroy the usability of the model by contaminating training samples,so such attacks are called causative availability indiscriminate *** the problem that existing data sanitization methods are hard to apply to real-time applications due to their tedious process and heavy computations,we propose a new supervised batch detection method for poison,which can fleetly sanitize the training dataset before the local model *** design a training dataset generation method that helps to enhance accuracy and uses data complexity features to train a detection model,which will be used in an efficient batch hierarchical detection *** model stockpiles knowledge about poison,which can be expanded by retraining to adapt to new *** neither attack-specific nor scenario-specific,our method is applicable to FL/DML or other online or offline scenarios.

International Conference on Networked Sensing Systems (INSS)

作者： Jan Beutel Matthias Dyer Roman Lim Christian Plessl Matthias Wohrle Mustafa Yucel Lothar Thiele Computer Engineering and Networks Lab ETH Zurich Zurich Switzerland

The design of distributed, wireless, and embedded system is a tedious and error-prone process. Experiences from previous real-world wireless sensor network (WSN) deployments strongly indicate that it is vital to follow a systematic design approach to satisfy all design requirements including robustness and reliability. Such a design methodology needs to include an end-to-end testing methodology. The proposed framework for WSN testing allows to apply distributed unit testing concepts in the development process. The tool flow decreases test time and allows for monitoring the correctness of the implementation throughout the development process.

International Conference on Networked Sensing Systems (INSS)

作者： Andreas Meier Jan Beutel Roman Lim Lothar Thiele Computer Engineering and Networks Lab ETH Zurich Zurich Switzerland

This paper describes the design and implementation of a high-reliability and low-power status monitoring protocol, e.g. for wireless alarm systems. The dual design approach followed consists of an in-depth device characterization with subsequent algorithm development. This allows to understand and leverage the correct design and implementation of the most critical components of the algorithms. The high-reliability status monitoring protocol operates based on monitoring windows with synchronous notification, subsequent acknowledgement rounds and periods of reduced activity, at regular intervals. This leads to deterministic and thus highly reliable operation of the status monitoring protocol implementation on the Tmote Sky platform.

In this paper, we propose an object-oriented attack model to represent a protocol attack in WSN detailedly. The model describes multiple attributes of an attack, including its principle, impact, interdependent relationships with other attacks, etc. Then, on the basis of the attack model and the FSM description method, we present a security testing approach for WSN protocols, in order to evaluate the security of the tested protocols. Finally, we take the TinyPK protocol and Sybil attack for example to implement our design, and the Protocol Security Testing Report shows as expected that the TinyPK cannot resist the Sybil attack Thus, the security testing approach proposed is feasible. © 2011 IEEE.

Security protocols for wireless sensor network are designed to provide a variety of security services to secure communications in an unsafe network. It is demanded to verify whether an implementation of a security protocol indeed perform as described in the protocol. In practice, conformance testing is commonly employed to test whether an implementation is conformance with the protocol specification. However, existing conformance testing cannot test and assess the security of the implementation of a security protocol. Therefore, randomness test is added to conformance test, makes it possible to test security functions. In this paper, we seek to overcome the limitation and meet the test requirement. We integrate randomness test with conformance testing to makes it possible to test security functions. One part of SPINS protocol is chosen to illustrate the approach. The experimental results demonstrate that the approach can be used for test security functions of WSN protocols. © 2011 IEEE.
