This document discusses wireless sensor networks. It outlines their applications such as environmental monitoring, health care, and military uses. It also examines factors that influence sensor network design like fault tolerance, scalability, production costs, and power consumption. The communication architecture of sensor networks is presented, including the application, transport, network, data link, and physical layers. Sensor networks have the potential to be widely used in many applications due to their flexibility and fault tolerance.
Black Hole Attack:
A malicious node advertises the wrong paths as good paths to the source node during the pathfinding process.
When the source selects the path including the attacker node, the traffic starts passing through the adversary node and this node starts dropping the packets selectively or in whole.
Black hole region is the entry point to a large number of harmful attacks.
Wireless Sensor Network (WSN) consists of sensor nodes which interact with each other through physical parameters like sunlight, wind, vibration, humidity etc. Routing protocols provide an optimal data transmission route from sensor nodes to sink node to save energy of nodes. From Base Station (BS) Sensor node sends and receives data to or from wireless stations. Clustering mechanism is one of the popular routing mechanisms used in WSN for optimizing the problem in sensor nodes. There are two types of clustering schemes known as homogeneous schemes and heterogeneous schemes. In Homogeneous scheme initial energy is same for each node but in heterogeneous scheme initial energy is different for each node and also used to determine the efficiency of sensor networks. Enhanced Modified LEACH (EMODLEACH) is a reactive protocol which is implemented for homogeneous network model. We have implemented the concept of Efficient Cluster head Replacement scheme and Dual transmitting power level scheme of MODLEACH along with the concept of Efficient Intra Cluster transmission Scheme of TEEN in LEACH. We analyze the PEGASIS protocol and modified the exiting protocol called improved energy balanced routing protocol (IEBRP).This IEBRP is based on cluster formation, cluster routing and other aspects of LEACH protocol.
This ppt describes about the Different protocols of Ad-Hoc Network .It is a pure survey report which will make clarification about each protocols used in ad-hoc network and helps to future generation to make more publishing of recent trends of ad-hoc networks.

Low Power Wireless Sensor Network Technologies and Standards for the Internet...Duncan Purves
Presentation on Low Power Wireless Sensor Network Technologies and Standards for the Internet of Things given at Institute of Physics, Sensors & their Applications XVIII Conference, 12 September 2016
sensors are what we experience the most in our life. they are even working in our body in different aspects. they may be as eyes, ears, skin, tongue etc. when we combine them they make a network. it may be a human sensor network. but i have shared something interesting about wireless sensor networks.
This presentation is all about the wireless sensor networks, how they collect data using aggregation, and how they evaluate or calculate the parameters
Wireless sensor networks make use of sensor nodes distributed in a sensor node field. There are many factors that influence the sensor network design. Sensor networks have their own protocol stack aligned with the OSI model.
In this thesis work, firstly an attempt have been made to evaluate the performance of DSR and OLSR routing protocol in mobile and static environments using Random Waypoint model, and also investigate how well these selected protocols performs on WSNs. energy efficient routing in wireless sensor networks thesis

UNIT IV WIRELESS SENSOR NETWORKS (WSNS) AND MAC PROTOCOLS 9 Single node architecture: hardware and software components of a sensor node - WSN Network architecture: typical network architectures-data relaying and aggregation strategies -MAC layer protocols: self-organizing, Hybrid TDMA/FDMA and CSMA based MAC- IEEE 802.15.4.
A wireless sensor network has important applications such as remote environmental monitoring and target tracking, particularly in recent years with the help of sensors that are smaller, cheaper, and intelligent. Sensors are equipped with wireless interfaces with which they can communicate with one another to form a network. A WSN consists of a number of sensor nodes (few tens to thousands) working together to monitor a region to obtain data about the environment. The design of a WSN depends significantly on the application, and it must consider factors such as the environment, the applications design objectives, cost, hardware, and system constraints.
Current Activities in WSN: Developing test bed for target tracking Using Passive Infrared and Ultrasonic Sensors Improving the delivery rate in low power wireless networks .Guided Navigation of Friendly Vehicle towards tracked Object. Design and development of smart mines and explosive ordinance for intelligent activation and deactivation and safe recovery based on secure WSN.

A Top-down Hierarchical Multi-hop Secure Routing Protocol for Wireless Sensor...ijasuc
This paper proposes a new top-down hierarchical, multi-hop, secure routing protocol for the wireless
sensor network, which is resilient to report fabrication attack. The report fabrication attack tries to
generate bogus reports by compromising the sensor nodes to mislead the environment monitoring
application executed by randomly deployed wireless sensor nodes. The proposed protocol relies on
symmetric key mechanism which is appropriate for random deployment of wireless sensor nodes. In the
proposed protocol, base station initiates the synthesis of secure hierarchical topology using top down
approach. The enquiry phase of the protocol provides assurance for the participation of all the cluster
heads in secure hierarchical topology formation. Further, this methodology takes care of failure of head
node or member node of a cluster. This protocol ensures confidentiality, integrity, and authenticity of the
final report of the monitoring application. The simulation results demonstrate the scalability of the
proposed protocol.

Interference Revelation in Mobile Ad-hoc Networks and Confrontationirjes
In this paper, we utilize the Several interference revelation techniques proposed for mobile ad hoc
networks rely on each node passively monitoring the data forwarding by its next hop. This paper presents
quantitative evaluations of false positives and their impact on monitoring based interference revelation for ad
hoc networks. Experimental results show that, even for a simple three-node configuration, an actual ad-hoc
network suffers from high false positives; these results are validated by Markov and probabilistic models.
However, this false positive problem cannot be observed by simulating the same network using popular ad hoc
network simulators, such as ns-2, OPNET or Glomosim. To remedy this, a probabilistic noise generator model
is implemented in the Glomosim simulator. With this revised noise model, the simulated network exhibits the
aggregate false positive behavior similar to that of the experimental tested. Simulations of larger (50-node) ad
hoc networks indicate that monitoring-based interference revelation has very high false positives. These false
positives can reduce the network performance or increase the overhead. In a simple monitoring-based system
where no secondary and more accurate methods are used, the false positives impact the network performance in
two ways: reduced throughput in normal networks without attackers and inability to mitigate the effect of
attacks in networks with attackers.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
