Three advantages of a relational database include maintaining data integrity through validation rules, reducing data duplication and redundancy, and better security management. Relational databases also provide program-data independence and allow queries and reports to be produced easily. Data inconsistency can occur when copies of a data item appear in different tables but are not consistent, and data duplication occurs when the same data is unnecessarily repeated in multiple tables.

The document summarizes research on detecting node replication attacks in mobile sensor networks. It discusses challenges in applying existing witness-finding strategies from static networks to mobile ones due to nodes' changing locations over time. Existing velocity-exceeding detection methods rely on centralized processing at the base station, incurring single point of failure issues. The paper then proposes localized detection algorithms that can effectively detect node replication in a distributed manner without requiring network-wide synchronization or revocation. The algorithms aim to overcome limitations of prior work in efficiently detecting replicas in mobile sensor networks.
Genomic projects provided clone resources for coding mRNAs, but non-coding mRNAs are still missing for functional studies. Seeing the growing number of non-coding mRNAs, we hope the community will prepare better resources for studying human non-coding mRNAs.
1) The document discusses various protocols for data propagation in wireless sensor networks, including flooding, gossiping, SPIN, Directed Diffusion, and LEACH.
2) SPIN is described as being simpler to implement than other protocols and more energy-efficient than flooding or gossiping while distributing data at the same or faster rates.
3) LEACH is a cluster-based approach that aims to reduce energy dissipation and increase network lifetime by distributing energy consumption evenly among sensors through randomized rotation of cluster-head positions.
The document proposes two novel node clone detection protocols for wireless sensor networks. The first protocol is based on a distributed hash table (DHT) that constructs a decentralized caching and checking system to effectively detect cloned nodes. It provides high security and efficient storage consumption. The second protocol, called randomly directed exploration, provides highly efficient communication performance for dense networks through probabilistic directed forwarding and border determination. It achieves adequate detection probability while consuming minimal memory. Both protocols address weaknesses in existing approaches and improve security, storage, communication, and detection performance for wireless sensor networks.
This paper presents a new receiver-initiated multicast algorithm called Robber for distributing large amounts of data from one cluster to multiple other clusters in grid computing environments. Robber is inspired by BitTorrent but is designed specifically for cluster grids. It uses a cooperative approach where nodes in the same cluster work together to efficiently retrieve data from peer clusters. Unlike static load balancing approaches, Robber dynamically adapts the workload of each node based on its relative performance within a cooperative. This avoids slower nodes from degrading overall throughput. The paper evaluates Robber experimentally and shows it outperforms BitTorrent and an earlier static load balancing approach, achieving throughput competitive with ideal multicast when bandwidth is stable and adapting better when bandwidth changes.
The document summarizes research on "Vampire Attacks" that drain the batteries of nodes in wireless sensor networks over time rather than disrupting immediate availability. It introduces the classification of these long-term denial of service attacks and outlines several representative attacks, such as carousel and stretch attacks, that exploit vulnerabilities in stateless source routing protocols. Simulation results show these attacks can increase network-wide energy usage by factors of up to 10 by artificially lengthening packet routes. The paper aims to evaluate vulnerabilities of existing protocols, quantify attack impacts, and modify protocols to provably bound damage from these resource depletion attacks.

Data Security and Data Dissemination of Distributed Data in Wireless Sensor N...IJERA Editor
The document discusses a data dissemination protocol called seDrip for wireless sensor networks. seDrip allows multiple authorized network users to simultaneously distribute data items directly to sensor nodes, without relying on a central sink node. It implements authentication using digital signatures to provide security and prevent unauthorized access. The protocol is analyzed and shown to satisfy security requirements like authenticity, integrity, and resistance to denial-of-service attacks. RSA encryption is used to encode data for confidentiality.
This document summarizes a research paper presented at the National Conference on Current Trends in Computer Science and Engineering. The paper proposes a Sink-initiated Geographic Multicast (SIGM) protocol for wireless sensor networks that allows mobile sinks to construct their own data delivery paths from a source node and merge these paths to form a multicast tree. This reduces location updates and achieves fast multicast tree construction and data delivery. The paper also presents a round-based virtual infrastructure to further improve the SIGM protocol's energy efficiency and ability to handle sink mobility. Simulation results show SIGM outperforms other source-initiated multicast protocols in terms of energy consumption and data delivery latency.
The document discusses vampire attacks on wireless sensor networks and proposes a solution called PLGPa. It defines vampire attacks as creating messages by malicious nodes that drain the battery life of honest nodes by forcing them to process unnecessary packets. It describes two types of attacks on stateless and stateful routing protocols, such as carousel and stretch attacks. The existing Clean Slate Sensor Network Routing protocol called PLGP is explained, but it is vulnerable to vampire attacks since nodes cannot verify packet paths. The proposed solution, PLGPa, adds verifiable path histories to packets using signature chains so that nodes can enforce the no-backtracking property and prevent packet diversion by vampires, making the network resistant to these attacks.
This document discusses different network steganography techniques, including tools developed to implement them. It describes using packet delay modification (Timeshifter) and packet content modification (Stegnet and BitStegNet) to covertly transmit messages. Timeshifter modifies ICMP packet delays.

The document outlines the goals, techniques tested, accomplishments and limitations of each tool, concluding future work could include testing in open networks and improving usability.
Iaetsd quick detection technique to reduce congestion inIaetsd Iaetsd
This document proposes a quick detection technique (QDT) to avoid congestion in wireless sensor networks. QDT uses the queue buffer length of sensor nodes to estimate impending congestion and diffuses traffic across multiple paths to the base station. By dynamically routing traffic away from congested areas, QDT aims to improve packet delivery ratios and event reporting while avoiding congestion. The technique detects inactive nodes that do not properly forward or drop packets, and routes around them to reduce delays and maximize network lifetime. Simulation results show QDT significantly improves event reporting and packet delivery compared to other techniques.

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.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

2. Introduction
At present, DNA sequencing methods have been widely emerged
and they are collectively known as next generation sequencing
methods.
Next generation sequencing has the ability to dramatically accelerate
biological researches by analyzing genomes cheaply and quickly
rather than requiring significant production-scale efforts.
This results in the production of huge sequence datasets.
Meanwhile, cloud computing has become a prominent technology in
many more areas.
3. Problem Addressed
The production of large data sets in next generation sequencing
leads to an additional computational challenges in data mining and
sequence analysis.
This represents a significant overburden so that high quality
sequencing techniques must be considered.
Focus: Analyzed the existing literature and find next generation
sequencing methods, its applications, cloud computing and its
applications in biological systems and the effect of cloud computing in
next generation sequencing.
4. Background
Fact 1: In 2003, successfully completed the sequencing of human genome
project.
Fact 2: Sanger sequencing technology used to sequence the human
genome.
Fact 2: It required over a decade to deliver the final draft.
Fact 3: In contrast, using next generation sequencing an entire genome can
be sequenced within a single day.

Sanger Sequencing
2. Second Generation Sequencing
Roche 454 System
AB SOLiD System
Illumina Genome Analyzer
3. Third Generation Sequencing
Heliscope TM Single Molecule Sequencer
Single Molecule Real Time Sequencer
Progress So Far:
7. First Generation Sequencing
• Fact 1: In 1975, Sanger introduced the concept of DNA sequencing.
• Fact 2: Later on, published a rapid method for determining sequences in DNA
by prime synthesis with DNA polymerase enzyme.
• Fact 3: In 1977, two landmark articles for DNA sequencing were published.
1. The Frederick Sanger’s enzymatic dydeoxy DNA sequencing technique based on the
chain terminating method.
2. Allam Maxam and Walter Gilbert’s chemical degradation DNA sequencing
technique.
8. Next Generation Sequencing
Fact 1: In 2000, Jonathan founded 454 Life Sciences, which further developed
the first commercially available NGS platform, the GS 20.
Fact 2: The developed technique was successfully validated by combining
single-molecule emulsion PCR with pyrosequencing.
• In general, the principle of pyrosequencing technique is based on the
“sequencing by synthesis”.
• It differs from Sanger sequencing because, it depends on the detection of
pyrophosphate release on nucleotide incorporation, rather than chain
termination with dideoxynucleotides.
9. Second Generation Sequencing
• The second generation HT-NGS platforms can generate about five hundred
million bases of raw sequence (Roche) to billions of bases in a single run.
• The second generation NGS platforms are based on template preparation,
massively parallel clonal amplification and sequencing and alignment of
short reads.
• There are three widely used NGS platforms.
1. Roche/ 454 system
2. ABI SOLiD system
3. Illumina genome analyzer
10. Second Generation Sequencing
Roche/ 454 System

• One DNA fragment per
bead
• Sequencing by ligation
• Read length ~50
Illumina System
• Solid amplification
• One DNA fragment per
cluster
• Sequencing synthesis
• Read length ~100
12. Using second generation techniques for DNA
Sequencing
Progress So Far:
The principle was based on the emulsion PCR amplification of the DNA
fragments, to make the light signal strong enough for reliable base detection
by the cameras.
Problem: It may introduce base sequence errors or favor of certain
sequences over others, thus changing the relative frequency and abundance
of various DNA fragments that existed before amplification.
SOLUTION: Determine the sequence directly from a single DNA
molecule, without the need for PCR amplification.
13. Third generation NGS Platforms
• The sequencing from a single DNA molecule is known as “third generation
NGS sequencing”.
• Progress So Far:
• Heliscope TM Single Molecule Sequencer
• Single Molecule Real Time Sequencer

15. Applications of Next Generation Sequencing
1. Full-genome resequencing or more targeted discovery of mutations or
polymorphisms.
2. Mapping of structural rearrangements, which may include copy number
variation, balanced translocation breakpoints and chromosomal inversions.
3. RNA-sequencing, analogous to expressed sequence tags or serial analysis of
gene expression.
4. Large- scale analysis of DNA methylation, by deep sequencing of bisulfite-
treated DNA.
5. Genome wide mapping of DNA-protein interactions, by deep sequencing of
DNA fragments.
16. Cloud Computing
Fact 1: Clouds can be categorized into three types based on the availability of
the data center.
• Public clouds- clouds owned and operated by third parties aiming at
individual client satisfaction by providing services at lower cost.
• Private clouds- clouds that are owned and operated by enterprises for their
own use and benefits.
• Hybrid clouds- the combination of both public and private clouds.
17. Cloud Computing
Fact 2: The services provided under cloud computing can be categorized into
three groups.
Software as a service (SaaS): software is served on demand to the clients.
Multiple users are serviced using single software without investing in
licenses.
Platform as a service(PaaS): A working platform is provided as a service by
encapsulating the required software and working environment to the
provider.
Infrastructure as a service(IaaS): provides computing capabilities and basic
storage over the network.
