A Comparison of Routing Protocol for WSNs: Redundancy Based Approach A Compar...ijeei-iaes
Wireless Sensor Networks (WSNs) with their dynamic applications gained a tremendous attention of researchers. Constant monitoring of critical situations attracted researchers to utilize WSNs at vast platforms. The main focus in WSNs is to enhance network localization as much as one could, for efficient and optimal utilization of resources. Different approaches based upon redundancy are proposed for optimum functionality. Localization is always related with redundancy of sensor nodes deployed at remote areas for constant and fault tolerant monitoring. In this work, we propose a comparison of classic flooding and the gossip protocol for homogenous networks which enhances stability and throughput quiet significantly.
This document discusses routing strategies in delay tolerant networks (DTNs) using wireless sensor network (WSN) nodes for localization applications. It first provides background on WSNs and DTNs, and then reviews common DTN routing protocols like epidemic routing, PROPHET, spray and wait, and MaxProp. The aim of the dissertation is to propose a new routing protocol for DTNs using WSN nodes where GPS is unavailable. It discusses using a hybrid of knowledge-based and additional node-based routing. The document outlines simulating the proposed filtered flooding protocol in NS-2 to evaluate delivery ratio and delay for a mining activity scenario. Results show delivery ratio is high for small networks but decreases with more nodes, while delay is

Characterization of directed diffusion protocol in wireless sensor networkijwmn
Wireless sensor network (WSN) has enormous applications in many places for monitoring the environments
of importance. Sensor nodes are capable of sensing, computing, and communicating. These sensor nodes
are energy constraint and operated by batteries. Since energy consumption is an important issue of WSN,
there have been many energy-efficient protocols proposed for the WSN. Directed diffusion (DD) is a datacentric
protocol that focuses on the energy efficiency of the networks. Since the first proposal of DD
protocol by Deborah, there have been various versions of DD protocols proposed by many scientists across
the globe. These upgraded versions of DD protocols add on various features to the original DD protocol
such as energy, scalability, network lifetime, security, reliability, and mobility. In this paper, we discuss
and classify various characteristics of themost populardirected diffusion protocols that have been proposed
over couple of years.
The development of the wireless sensor networks (WSNs) in various applications like Defense, Health,
Environment monitoring, Industry etc. always attract many researchers in this field. WSN is the network
which consists of collection of tiny devices called sensor nodes. Sensor node typically combines wireless
radio transmitter-receiver and limited energy, restricted computational processing capacity and
communication band width. These sensor node sense some physical phenomenon using different
transduces. The current improvement in sensor technology has made possible WSNs that have wide and
varied applications. While selecting the right sensor for application a number of characteristics are
important. This paper provides the basics of WSNs including the node characteristics. It also throws light
on the different routing protocols.

Data transmission occurs from transmitting node to sink node, which communicate each other via large number of intermediate nodes or directly to an external base station. A network consists of numbers of nodes with one as a source and one or more as a destination node.
The document discusses routing protocols for wireless sensor networks (WSNs). It provides an overview of routing challenges in WSNs, including energy constraints, data delivery models, fault tolerance, and quality of service issues. It then describes two common flat routing protocols for WSNs: SPIN and Directed Diffusion. SPIN uses data negotiation to disseminate information and avoid redundant transmissions. Directed Diffusion establishes interest gradients to route data from sources to a sink based on attribute-value pairs.

This document contains questions and answers related to networking concepts. It covers topics like the OSI model, TCP/IP protocols, routing, and Cisco devices. Some key points addressed include:
- The transport layer is responsible for reliable connections in the OSI model.
- The three VTP modes are server, client, and transparent.

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.
This document outlines the topics and policies for a network management course. The topics to be discussed include types of networks, network hardware, TCP/IP fundamentals, and TCP and UDP communications. Course policies cover attendance, assignment deadlines, exams, and conduct. Grading will be based on exams, assignments, attendance, and quizzes. The document then provides content on network types and topologies, network devices, and internetworking models like OSI and TCP/IP.
The document summarizes a student's M. Tech thesis project on improving routing protocols in wireless sensor networks. It begins with an objective to develop a hybrid routing protocol combining features of PEGASIS and LEACH to increase network lifetime. It then reviews related work on routing protocols and energy efficiency. The proposed methodology describes a hybrid protocol that selects cluster heads probabilistically like LEACH while forming chains to route data like PEGASIS. Simulation results show the hybrid protocol increases network lifetime to over 2000 rounds compared to 2000 rounds for previous work. The conclusion is that lower cluster head election probabilities in the hybrid protocol extend network lifetime. Future work could analyze different network parameters.
This document summarizes a research paper on reducing packet loss in mobile ad hoc networks (MANETs). The paper discusses how MANETs are vulnerable to various security threats like black hole attacks that can cause packet dropping. It evaluates existing authentication schemes like ACK-based schemes that have overhead issues. The paper then proposes a modified ACK-based scheme using finite state automata to overcome decision ambiguity and minimize packet dropping while authenticating nodes in the MANET. Simulation results show that the proposed approach improves packet delivery ratio, throughput and reduces routing load compared to not using secure authentication.

Here are the key points about how mobility support for both the correspondent and mobile host would affect end-to-end delays:
- Datagrams would need to be tunneled through multiple home agents to reach the destination, adding additional encapsulation and forwarding hops.
- The path taken by a datagram would become more indirect as it travels through multiple home agents rather than direct host-to-host routing. This increases propagation and transmission delays.
- Additional processing is required at each home agent to encapsulate/decapsulate and forward the datagram, increasing processing delays.
- If either the mobile host or correspondent changes locations, their registrations with home agents and mobility bindings need to be updated, introducing additional

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development.
