INTRODUCTION A Wireless Sensor Network or WSN is supposed to be made up of a large number of sensors and at least one base station. The sensors are autonomous small devices with several constraints like the battery power, computation capacity, communication range and memory. They also are supplied with transceivers to gather information from its environment and pass it on up to a certain base station, where the measured parameters can be stored and available for the end user. In most cases, the

Introduction: From the past few years wireless sensor networks (WSN’s) have gained global attention. It is a promising technology that has been extensively used in various critical and long-lasting applications. A Wireless Sensor Network (WSN) has a large number of energy constrained sensor nodes that have the capability to compute and communicate. They are used to identify the events of interests and transfer the data to the sink node. WSN is categorized into fixed WSN and mobile WSN. Target area

server and the MQTT-SN gateway. Its main function is the translation between MQTT and MQTT-SN. MQTT-SN clients can also access a gateway via a forwarder in case the gateway is not directly attached to the network. The forwarder simply encapsulates the MQTT-SN frames it receives on the sensor network side and forwards them unchanged to the gateway; in the opposite direction, it decapsulates the frames it receives from the

Introduction: The central theme of this essay focuses on the impact of cloud on the organization’s network infrastructure. While going through the impact we will also analyze how to optimize network performance for cloud and we will also discuss about how the cloud impact the lifecycle orchestration and the organization. The key aspect o the cloud is discussed in detail with suitable examples. Background: The cloud computing is noting but storing the data and information n the internet, instead

members within each group… 5. Which of the following is the reason why neural networks have been applied in business classification problems? Able to learn the data, able to learn the models ' nonparametric nature, its ability to generalize, All of the above 6. The main processing elements of a neural network are individual neurons 7. A software suite is

Efficient resource allocation in cognitive radio networks considering time varying constraints Abstract: Wide spread acceptance of wireless technologies has given rise to increase in demand for bandwidth .cognitive radio was developed as a promising technique to overcome the scarcity of spectrum resources in wireless communication. The term cognitive radio is defined as an intelligent radio that can be programmed and configured dynamically. Particular portion of the spectrum can be used only by

A Mechanism for Detection of Cooperative part attack in Mobile Ad Hoc Networks “Jaydip Sen ; Sripad Koilakonda ; Arijit Ukil” A mobile impromptu network (MANET) could also be a assortment of autonomous nodes that communicate with one another by forming a multi-hop radio network and maintaining connections in an extremely localized manner. Security remains a significant challenge for these networks due to their choice of open medium, properly dynamical topologies, reliance on cooperative algorithms

one of the most important issues of any secure communication with the increasing demand for the security in wireless sensor networks (WSNs) it is important to introduce the secure and reliable key management in the WSNs.Data confidentiality and authenticity are critical in WSNs. Key management objective is to secure and keep up secure connections between sensor nodes at network formation and running stages. In this paper we proposed various key management schemes, necessity for key management and security

building of social networks or social relations among us when we share interests, activities, backgrounds, or real-life connections. A social network service involves the representation of each user (often a profile), his/her social links, and a variety of additional services. Most social network services are web-based and provide means for users to interact over the Internet, such as e-mail and instant messaging. Online community services are seldom considered as a social network service, though in
