Abstract—Industrial Ethernet is the preferred network technology in industrial green field deployments. Active devices interconnecting the nodes are switches. In an industrial deployment, nodes are typically located on the same Layer 2 network. Routers or firewalls are almost exclusively used at the network edges. The current trend on engineering of industrial devices is to include an embedded Ethernet switch, instead of using discrete units.

Multi-Tiered Communication Security Schemes in Wireless Ad-Hoc Sensor NetworksIDES Editor
Networks of wireless micro-sensors for monitoring
physical environments have emerged as an important new
application area for wireless technology. Key attributes of
these new types of networked systems are the severely
constrained computational and energy resources and an ad
hoc operational environment. This paper is a study of the
communication security aspects of these networks. Resource
limitations and specific architecture of sensor networks call
for customized security mechanisms. Our approach is to
classify the types of data existing in sensor networks, and
identify possible communication security threats according
to that classification. We propose a communication security
scheme where for each type of data we define a corresponding
security mechanism. By employing this multi-tiered security
architecture where each mechanism has different resource
requirements, we allow for efficient resource management,
which is essential for wireless sensor networks.

A honeynet framework to promote enterprise network securityIAEME Publication
This document describes a honeynet framework to promote enterprise network security. The framework consists of two high-interaction honeypot servers connected by a switch to a monitoring station. The honeypots provide real operating systems and services to attract attackers. When an attacker attempts to access a honeypot, its data is captured by a packet sniffer and stored in a database. This data is then sent securely to the monitoring station using web services. The monitoring station analyzes the data, generates an alert report, and provides a GUI to monitor extracted information. The goal is to identify attack traffic and profile attackers to improve network defense.

ACCELERATED DEEP LEARNING INFERENCE FROM CONSTRAINED EMBEDDED DEVICESIAEME Publication
Hardware looping is a feature of some processor instruction sets whose hardware can repeat the body of a loop automatically, rather than requiring software instructions which take up cycles (and therefore time) to do so. Loop Unrolling is a loop transformation technique that attempts to advance a program's execution speed to the detriment of its twofold size, which is a methodology known as space–time tradeoff. A convolutional neural network is created with simple loops, with hardware looping, with loop unrolling and with both hardware looping and loop unrolling, and a comparison is made to evaluate the effectiveness of hardware looping and loop unrolling. The hardware loops alone will add to a cycle check decline, while the mix of hardware loops and dot product instructions will decrease the clock cycle tally further. The CNN is simulated on Xilinx Vivado 2021.1 running on Zync-7000 FPGA.

Wireless Sensor Networks have acquired a lot of attention by research community, manufacturer as well as actual users for monitoring remote trades and how to gather data in different environment. The wireless sensor nodes are especially battery powered devices having life can be extended for some times while long lasting and reliable for maintaining consumption of energy and network lifetime while designs applications and protocols. So it is essential to design effective and energy efficient protocol in order to enhance the network lifetime. In this paper we present the study of different energy efficient communication protocols of Wireless Sensor Networks (WSNs).Then some of the communication protocols which are widely used in WSNs to improve network performance are also discussed advantages and disadvantages of each protocols.

Mobile Ad hoc Networks are exceptional cases of ad hoc networks that, but it is lacking infrastructure, communicating entities pass with various accelerations. For that reason, this impedes or delay lays the foundation of well built end-to-end communication paths. So Mobile Ad-hoc Network having efficient data transfer. In this manner, MANETs have out of the common network concerns and security challenges to get the advanced connectivity, immune communications, and reputation executives systems which have an impact on the trust in cooperation and settlement between mobile networking units. In this survey paper we confer about the security attributes, attacks, and challenges of MANETs.So, it is important to have a better and good formation algorithm to connect all the nodes to each other.

Reliable Metrics for Wireless Mesh NetworkIRJET Journal
This document discusses routing metrics for wireless mesh networks. It describes three common routing metrics: Expected Transmission Count (ETX), Expected Transmission Time (ETT), and Load Aware Expected Transmission Time (LAETT). ETX considers only link quality, while ETT also considers transmission rates but not traffic load. LAETT builds on ETT by incorporating remaining capacity to capture load and introduce load balancing. The document analyzes these three metrics based on packet delivery ratio, throughput, and bandwidth utilization based on simulation results. It finds that ETT and LAETT show better performance than ETX on these metrics by more fully capturing factors like transmission rates and traffic loads.

The work with feature of self-power supply by solar cell or by the battery or together at the same time. Therefore, the power dissipation is the big problem in wireless sensor network (WSN) especially when it is works for long time. The efficient method for reducing the power consumption within working is needed. The process of reducing waste power is one of the top priorities of scientists and designers of wireless sensor networks. The aim of this paper is to find the dominant method to reduce the power consumption in the wireless sensor network in order to stay works for long time and maintain the links with other nodes without loss of connection and transfer the information correctly. In this paper, a modified method was invented to minimize power utilization per data bit in a connection. This new method depends on the optimization process for reducing the power consumption as low as possible. All the tests of simulation process were done in additive white Gaussian noise (AWGN) channel. Numerical results demonstrated that the new method reduce the power when different values of noise are present with different types of modulation. Also the distance that the WSN will reach the information to it will be increase with presence of various noise amounts with different types of modulation. As a result, the power was decreased and the signal was reach more distance.

IRJET-Structure less Efficient Data Aggregation and Data Integrity in Sensor ...IRJET Journal
This document proposes a structureless and efficient data aggregation technique for wireless sensor networks that ensures data integrity with low transmission overhead. It introduces a concept where the base station can recover individual sensor data even after aggregation by cluster heads. This allows the base station to verify data integrity and authenticity, as well as perform any desired aggregation functions. It then proposes a structure-free scheme using intracluster and intercluster encryption and aggregation procedures. This scheme aims to address limitations of previous work such as high transmission costs and inability to query individual data values, while maintaining security and scalability. The document analyzes security and scalability aspects and argues the proposed scheme offers improved performance and efficiency for data aggregation in wireless sensor networks.

Stable Ethernet TCP/IP Real Time Communication In Industrial Embedded Applica...IJRES Journal
This paper discusses using Ethernet for real-time communication in industrial embedded applications. It first reviews using switched Ethernet to eliminate collisions and enable real-time data transmission. It then examines different industrial Ethernet technologies like EtherCAT and how priority scheduling and other techniques can enhance real-time performance. Various simulation results are presented showing the impact of parameters like packet processing rate and non-real-time traffic on latency. Finally, it concludes that industrial Ethernet networks using intelligent switching can offer advantages over traditional networks while enabling Internet connectivity if techniques like traffic shaping and multicasting are used.
This document discusses various local area network (LAN) technologies. It begins by defining LANs and explaining that they can connect devices within a single building or across multiple buildings. Common LAN technologies discussed include Ethernet, Token Ring, fiber, and wireless networks. Ethernet is currently the most widely used standard. Fast Ethernet and Gigabit Ethernet are also covered as higher-speed successors to standard Ethernet. The document also examines protocols, the OSI model, Ethernet coding standards, and different types of media like twisted pair and fiber optic cables.
The document describes a security protocol called SPINS (Security Protocols for Sensor Networks) that is optimized for resource-constrained wireless sensor networks. SPINS consists of two security building blocks: SNEP and TESLA. SNEP provides data confidentiality, authentication, integrity and freshness with low overhead. TESLA provides authenticated broadcast, which is challenging for sensor networks. The protocols were implemented on prototype sensor nodes and shown to perform well within the limited capabilities of the hardware.
As sensor networks edge closer towards wide-spread placement, security issues become a central concern. So far, much research has concentrated on making sensor networks feasible and useful, and has not focused on security.
We present a set of security building blocks optimized for resource constrained environments and wireless communication. SPINS has two secure building blocks: SNEP and TESLA. SNEP provides the following important baseline security primitives: Data confidentiality, two-party data authentication, and data freshness. A particularly hard problem is to provide effective broadcast authentication, which is an important mechanism for sensor networks. TESLA is a new protocol which provides authenticated broadcast for severely resource-constrained surroundings. We realized the above protocols, and show that they are practical straighly on minimal hardware: the performance of the protocol suite easily matches the data rate of our network. Additionally, we prove that the suite can be used for building higher level protocols
Analysis Of Internet Protocol ( IP ) DatagramsEmily Jones
Here are the key points about wireless sensor networks:
- WSN consist of small, low-cost sensors that can sense and monitor various environments and phenomena. They communicate wirelessly to form dense networks.
- The sensors have limited processing, storage and power capabilities. They must operate autonomously for long periods with small batteries or energy harvesting.
- WSN enable ubiquitous sensing and monitoring without being constrained by wires. They provide more flexibility in deployment compared to wired networks.
- Common applications of WSN include environmental/habitat monitoring, healthcare applications, home automation, traffic control, and industrial/machine monitoring.
- Key technical challenges in WSN include limited power/energy, dynamic network topology, fault tolerance
1) The document discusses the differences between standard Ethernet networks and proprietary "standards-based" industrial Ethernet networks.
2) A standard Ethernet network complies fully with IEEE 802.3, uses unmodified TCP/IP protocols, and has an approved industrial application layer.
3) Many proprietary networks claim to be "standards-based" but modify IEEE 802.3, bypass or modify TCP/IP, or lack a complete application layer profile. This makes them non-standard.
Advantages And Disadvantages Of ATM Is A Deterministic...Susan Cox
This document discusses ATM monitoring and an RFP (request for proposal) process for ATM monitoring services. The author was leading the response for their company to a large RFP from a financial institution for monitoring their 3600 ATMs, which were currently serviced by Diebold. Though the company assumed they wouldn't win the bid, they provided a thorough response. Within a few weeks they were told Diebold was awarded the contract. However, the author was able to quickly put together resources and train them to take on the ATM monitoring work, which became a new successful service for their customer at a lower price than the previous provider.
Advanced Security Management in Metro Ethernet NetworksIJNSA Journal
With the rapid increase in bandwidth and the introduction of advanced IP services including voice, high-speed internet access, and video/IPTV, consumers are more vulnerable to malicious users than ever. In recent years, roviding safe and sound networks and services have been the zenith priority for service providers and network carriers alike. Users are hesitant to subscribe to new services unless service providers guarantee secure connections. More importantly, government agencies of many countries have introduced legislations requiring service providers to keep track and records of owners of IP and MAC addresses at all time. In this paper, we first present an overview of Metro Ethernet (or Ethernet-To-The-Home/Business (ETTx)) and compare with various IP broadband access technologies including DSL, wireless and cable. We then outline major security concerns for Metro Ethernet networks including network and subscriber/end user security. Next we introduce state-of-the-art algorithms to prevent attackers from stealing any IP or MAC addresses. Our proposal is to use network management in conjunction with hardware features for security management to provide a secure and spoofing-free ETTx network. The key idea behind our proposal is to utilize network management to enforce strict (port, MAC, IP) binding in the access network to provide subscriber security. The paper then proposes an adaptive policy-based security controller to quickly identify suspected malicious users, temporarily isolate them without disconnecting them from the network or validating their contracts, and then carry the required analysis. The proposed controller identifies malicious users without compromising between accurate but lengthy traffic analysis and premature decision. It also provides the ability to make granular corrective actions that are adaptive to any defined network condition.

There are different types of networks including local area networks (LANs) within a building, wide area networks (WANs) connecting multiple LANs over long distances, and metropolitan area networks (MANs) within a city. The Open Systems Interconnection (OSI) model describes how network components work together in layers to enable communication. Ethernet is a common physical layer technology used to set up LANs.
Wireless HART stack using multiprocessor technique with laxity algorithmjournalBEEI
The use of a real-time operating system is required for the demarcation of industrial wireless sensor network (IWSN) stacks (RTOS). In the industrial world, a vast number of sensors are utilised to gather various types of data. The data gathered by the sensors cannot be prioritised ahead of time. Because all of the information is equally essential. As a result, a protocol stack is employed to guarantee that data is acquired and processed fairly. In IWSN, the protocol stack is implemented using RTOS. The data collected from IWSN sensor nodes is processed using non-preemptive scheduling and the protocol stack, and then sent in parallel to the IWSN's central controller. The real-time operating system (RTOS) is a process that occurs between hardware and software. Packets must be sent at a certain time. It's possible that some packets may collide during transmission. We're going to undertake this project to get around this collision. As a prototype, this project is divided into two parts. The first uses RTOS and the LPC2148 as a master node, while the second serves as a standard data collection node to which sensors are attached. Any controller may be used in the second part, depending on the situation. Wireless HART allows two nodes to communicate with each other.

Performance Analysis of TCP and SCTP For Congestion Losses In ManetIJERA Editor
Transmission control protocols have been used for data transmission process. TCP has been pre-owned for data transmission over wired communication having different bandwidths and message delays over the network. TCP provides communication using 3-handshake which sends RTS and ACK comes from server end and data message has been transmitted over the bandwidth provided. This does not provide security over flooding attack occurred on the network. TCP provides communication between different nodes of the wired communication but when multi-streaming occurs in a network TCP does not provides proper throughput of the system which is major problem that occurred in the previous system. In the proposed work, to overcome this problem SCTP transmission control protocol has been implemented for the system performance of the system. SCTP provides 4-handshake communication in the message transmit due to which security factor get increases and this also provides communication services over multi-streaming and multi-homing. Multiple sender and receivers can communicate over wired network using various approaches of communication through same routers, which degrades in the TCP protocol. In final we evaluate parameters for performance evaluation. Here, we designed and implemented our test bed using Network Simulator (NS-2.35) to test the performance of both Routing protocols.
