Implementation of Lessar Algorithm for Analysis of Network Intrusion Detection System in Wireless Sensor Networks

Wireless sensor networks are the result of multiple technological advances in electronics, nanotechnology, wireless communications, computing power, network development and robotics. Compose distributed systems devices usually composed of integrated, including at least CPU, radio, and sensors / actuators number. The wireless sensor networks (WSN) heterogeneous networks are formed by sensors, gateways and backend resources very limited physical. The sensors can measure parameters such as temperature, movement, lighting, humidity, etc..; the gateways establish the link with networks traditional and familiar. The back ends are responsible for the processing and display unit the captured data. Although several studies showed WSN middleware, has not been achieved with this industry acceptance due mainly to the different methodologies programming. The teams consist of WSN lowest consumption, costs and form factors. The reality is quite different environments applications are supported with equipment more powerful and fed by redundant power networks. The current article describes then implementation of lesser algorithm for analysis of network intrusion detection system in wireless sensor networks

Improving energy efficiency in wireless sensor networks through scheduling and routing

This paper is about the wireless sensor network in environmental monitoring applications. A Wireless Sensor Network consists of many sensor nodes and a base station. The number and type of sensor nodes and the design protocols for any wireless sensor network is application specific. The sensor data in this application may be light intensity, temperature, pressure, humidity and their variations .Clustering and routing are the two areas which are given more attention in this paper.Comment: 7 Pages, 2 Figures and 1 Tabl

BANZKP: a Secure Authentication Scheme Using Zero Knowledge Proof for WBANs

-Wireless body area network(WBAN) has shown great potential in improving healthcare quality not only for patients but also for medical staff. However, security and privacy are still an important issue in WBANs especially in multi-hop architectures. In this paper, we propose and present the design and the evaluation of a secure lightweight and energy efficient authentication scheme BANZKP based on an efficient cryptographic protocol, Zero Knowledge Proof (ZKP) and a commitment scheme. ZKP is used to confirm the identify of the sensor nodes, with small computational requirement, which is favorable for body sensors given their limited resources, while the commitment scheme is used to deal with replay attacks and hence the injection attacks by committing a message and revealing the key later. Our scheme reduces the memory requirement by 56.13 % compared to TinyZKP [13], the comparable alternative so far for Body Area Networks, and uses 10 % less energy

Concepts and evolution of research in the field of wireless sensor networks

The field of Wireless Sensor Networks (WSNs) is experiencing a resurgence of interest and a continuous evolution in the scientific and industrial community. The use of this particular type of ad hoc network is becoming increasingly important in many contexts, regardless of geographical position and so, according to a set of possible application. WSNs offer interesting low cost and easily deployable solutions to perform a remote real time monitoring, target tracking and recognition of physical phenomenon. The uses of these sensors organized into a network continue to reveal a set of research questions according to particularities target applications. Despite difficulties introduced by sensor resources constraints, research contributions in this field are growing day by day. In this paper, we present a comprehensive review of most recent literature of WSNs and outline open research issues in this field
