Routing Protocols and Network Simulator in Multihop Wireless Ad-Hoc Network: A Review

Sudhir Singh, Rajeshwar Singh

Mobile Ad hoc Network (MANET) allows portable devices to establish communication independent of a central infrastructure.The wireless links in this network are highly error prone and can go down frequently due to mobility of nodes. Therefore, routing in MANET is a critical task due to highly dynamic environment.Efficient Rout-ing Protocols will make MANET reliable. Mainly protocols are of three kind i.e. Proactive, Reactive and hybrid. But, we will discuss Proactive and Reactive Protocols. Several Routing Protocols for MANET are Dynamic Source Routing (DSR), Ad hoc On-demand Distance Vector (AODV), Destination Sequence Distance Vector (DSDV) and Temporally Ordered Routing Algorithm (TORA). This paper presents the survey of Routing Protocols and NS2 in MANET and provides an overview of these protocols by presenting their characteristics, functionality, benefits and then their comparative analysis parameters. Depending on parameters one can compare the performance of Routing Protocols.

Anuj Singh, Mauli Joshi

The latest development in the modern publishing technologies, the layout of today’s documents has never been more complex. Most of them contain not only text and background regions, but also graphics, tables and pictures. Therefore scanned documents must often be segmented before other document processing techniques,such as compression or rendering, can be applied. The paper focus of the texture analysis and extraction from colour images after image segmentation. The basic idea behind segmentation is region growing and used to identify one or more criteria that are characteristic for the desired region. After establishing the criteria,the image is searched for any pixels that fulfill the requirements.Whenever such a pixel is encountered, its neighbors are checked,and if any of the neighbors also match the criteria, both the pixels are considered as belonging to the same region. The text extraction is carried out using HAAR Discrete Wavelet Transform (DWT)applied in MATLAB 2013 image processing tool. The paper alsodiscusses the masking technique applied for image segmentationalso.

Measuring Facts of Security Issues in Cloud Computing

Shipra Yadav, Keshao Kalaskar

Cloud computing has quickly become one of the most prominent buzzwords in the IT world due to its revolutionary model of computing as a utility. It promises increased flexibility, scalability,and reliability, while promising decreased operational and support costs. However, many potential cloud users are reluctant to move to cloud computing on a large scale due to the unaddressed security issues present in cloud computing. In this paper, I investigate the major security issues present in cloud computing today based on a framework for security subsystems adopted from IBM. I present the solutions proposed by other researchers, and address the strengths and weaknesses of the solutions. Although considerable progress has been made, more research needs to be done to address the multi-faceted security concerns that exist within cloud computing. Security issues relating to standardization, multi-tenancy, and federation must be addressed in more depth for cloud computing to overcome its security hurdles and progress towards widespread adoption.

Anu Priya Sunny, Biljy.P.H, Nandakumar.R

For an encryption engine the security of the key is the most important factor.it is not necessary to have a lengthy key for increased security. In this paper we are discussing about how to design a secure encrypyion algorithm (BLOWFISH) [2]using a key with variable length. Here the length of the key may vary from 32 bits to 448 bits. An efficient algorithm for key generation is explained in detail later in this paper. Here the input plain text and the output cipher text are of 64 bits. The input plain text after undergoing a series of operations gets transformed into the cipher text. Here we make use of one P-array(permutation array) and four S- boxes (substitution boxes). Both the P-array and four S-boxes are initialized with the hexadecimal equivalents of pi.The process of encryption and decryption are comparably the same except from the fact of utilizing the elements of P-array in the reverse order.

Ch. Anil Kumar

One of the main concerns when designing a key management scheme is the network scalability. Indeed, the protocol should support a large number of nodes to enable a large scale deployment of the network. In this paper, we propose a new scalable key management scheme for WSNs which provides a good secure connectivity coverage. For this purpose, we make use of the Symmetric-key design theory. We show that the basic mapping from Symmetric-key to key pre-distribution allows us to achieve high network scalability. we propose an enhanced Symmetrickey -based key pre- distribution scheme providing high network scalability and good key sharing probability providing high secure connectivity coverage and overall improved performance.

Ant Colony Optimization Based Software Effort Estimation

Nishu Dewan, Sumeet Kaur Sehra

Accurate software development cost estimation is important for effective project management such as budgeting, project planning and control. Nowadays there are many models for software development cost estimation, providing project managers with helpful information to make the right decisions. One of such well known mathematical models is the COCOMO model. To estimate costs and time, this model uses coefficients, which were determined in 1981 by means of the regression analysis of statistical data based on 63 different types of project data. Using these coefficients for a modern project, the appraisal may not be accurate; therefore, the aim of this work is to optimize the model coefficients with ant colony optimization algorithms. Firstly, collect and clean the data. The outliers are removed during analyzing the data. Then different paths are generated by ants. The best path is selected by using Ant colony optimization algorithm. The performance of the system is analyzed by mean magnitude of relative error. The percent improvement of proposed model over COCOMO model is 92.29%.

A Wireless Protocol to Prevent Wormhole Attack in Wireless Ad-Hoc Network

Anusha, Vikram Singh

The nature of wireless Ad-Hoc and sensor networks make them very attractive to attackers. One of the most popular and serious attack in wireless ad hoc and sensor network is the wormhole attack. It is a particularly severe attack on routing protocols for ad hoc networks in which two or more colluding attackers record packets at one location, and tunnel them to another location for a replay at that remote location. When this attack targets routingcontrol packets, the nodes that are close to the attackers are defended from any alternative routes with more than one or two hops to the remote location. All routes are thus directed to the wormhole established by the attackers. The wormhole attack is particularly challenging to deal with since the adversary does not need to compromise any nodes and can use laptops or other wireless devices to send the packets on a low latency channel. This Paper focuses on threat that wormhole attack possesses on network and also mentions one of the few initiatives with the respective specifications to solve the problem.

Now-A-Days, most of the people are showing interest on education. But it is very hard to get the job. So they prefer to the unrelated stream of education which are leading to the work in night time. Because of this reason, most of the companies are taking an advantage and run the companies even in the night times (though it’s not US bound process) But the employees of the companies are not provided with proper security precautions which in turn lead to theft, kidnaps & even rape n killings. For this GOVT has taken many precautions but they are hard to implement and cannot be well functioned. For example,The Delhi Police have issued a notice to safeguard women workers under Criminal Procedure Code (CRPC) 144 to all BPO companies, media and corporate houses in Delhi and the National Capital Region. Even though these days the women are willing to do the job for their economical and financial crisis. They are subjected too much insecurity concerning the job. For instance In November 2007 cab drivers Purushottam Borate and Pradeep Yashwant Kokoda kidnapped, raped and murdered Jyotikumari Choudhury who worked with a call center in Pune sending shock waves across the country especially amongst women who work in night shifts or at odd hours based on these circumstances, they are afraid to do their job at night time.
