Smart detection and prevention procedure for DoS attack in MANET

Tue, 02 Feb 2021 00:00:00 +0530

A self-organized wireless communication short-lived network containing collection of mobile nodes is mobile ad hoc network (MANET). The mobile nodes communicate with each other by wireless radio links without the use of any pre-established fixed communication network infrastructure or centralized administration, such as base stations or access points, and with no human intervention. In addition, this network has potential applications in conference, disaster relief, and battlefield scenario, and have received important attention in current years. There is some security concern that increases fear of attacks on the mobile ad-hoc network. The mobility of the NODE in a MANET poses many security problems and vulnerable to different types of security attacks than conventional wired and wireless networks. The causes of these issues are due to their open medium, dynamic network topology, absence of central administration, distributed cooperation, constrained capability, and lack of clear line of defense. Without proper security, mobile hosts are easily captured, compromised, and attacked by malicious nodes. Malicious nodes behavior may deliberately disrupt the network so that the whole network will be suffering from packet losses. One of the major concerns in mobile ad-hoc networks is a traffic DoS attack in which the traffic is choked by the malicious node which denied network services for the user. Mobile ad-hoc networks must have a safe path for transmission and correspondence which is a serious testing and indispensable issue. So as to provide secure communication and transmission, the scientist worked explicitly on the security issues in versatile impromptu organizations and many secure directing conventions and security measures within the networks were proposed. The goal of the work is to study DoS attacks and how it can be detected in the network. Existing methodologies for finding a malicious node that causes traffic jamming is based on node’s retains value. The proposed approach finds a malicious node using reliability value determined by the broadcast reliability packet (RL Packet). In this approach at the initial level, every node has zero reliability value, specific time slice, and transmission starts with a packet termed as reliability packet, node who responded properly in specific time, increases its reliability value and those nodes who do not respond in a specific time decreases their reliability value and if it goes to less than zero then announced that it’s a malicious node. Reliability approach makes service availability and retransmission time.

Neglected Tropical Diseases (NTDs) - A Snapshot of Research

Mon, 08 Mar 2021 00:00:00 +0530

More than a billion people-one-sixth of the earth's population is infected with one or more neglected tropical diseases (NTDs) in developing countries. Over the past decade, interests in NTDs have resurged as these are a barrier to achieving broader human development outcomes (e.g., improved newborn, child and maternal health, food, and nutritional safety). Several national and international organizations (such as the WHO, USAID, CDC, and others) concentrate on NTDs and fighting to control or prevent them. This review describes a brief introduction to NTDs, the global burden of the diseases in terms of disability-adjusted life years (DALYs), years lived with disability (YLDs) and years of life lost (YLLs). This paper also reviews the negative impact of these diseases on global economies and discusses strategies for public health to prevent and eliminate these diseases, the achievements and challenges that can be achieved to address adversity there.

Augmented reality marker-based technology for augmenting newspaper advertisement

Wed, 28 Apr 2021 00:00:00 +0530

In this research, we describe an augmented reality android-based idea in which we utilize augmented reality marker-based technology for augmenting newspaper advertisement with electronic information that does not modify the format of the newspaper document and remains exactly the same, substantially improves the utility of paper by reducing the portion of the printed Ad on the newspaper. An implementation on a camera phone is discussed that lets users retrieve data and access links from newspaper advertisements to electronic data. We carefully examined over twenty people of different ages and occupations who participated in the newspaper-based AR and we got a significant overall response. Further analysis implies that this may assist students in understanding the complex 3D objects, which they can manipulate, learn tasks and improve skills.
