Impact of Node Mobility on Routing Protocols for Wireless Sensor Networks
G. Santhosh Kumar, M.V. Vinu Paul and K. Poulose Jacob
Abstract”
1
Wireless sensor networks monitor their
surrounding environment for the occurrence of some
anticipated phenomenon. Most of the research related to
sensor networks considers the static deployment of sensor
nodes. Mobility of sensor node can be considered as an
extra dimension of complexity, which poses interesting
and challenging problems. Node mobility is a very
important aspect in the des ....etc

Abstract
A fundamental problem in wireless sensor networks is to maximize network lifetime under given energy constraints. In this paper, we study the network lifetime problem by considering not only maximizing the time until the first node fails, but also maximizing the lifetimes for all the nodes in the network, which we define as the Lexicographic Max-Min (LMM) node lifetime problem. The main contributions of this paper are two-fold. First, we develop a polynomial-time algorithm to derive the LMM-optimal node lifetime vector, which effec ....etc

SEMINAR ON FAST DETECTION OF MOBILE REPLICA NODE ATTACKS IN WIRELESS SENSOR NETWORKS

ABSTRACT

An adversary can capture and compromise sensor nodes, make replicas of them, and then mount a variety of attacks with these replicas.Several replica node detection schemes have been proposed. However, these schemes rely on fixed sensor locations and hence do not work in mobile sensor networks. In this project, a fast and effective mobile replica node detection scheme is proposed using the Sequential Probability Ratio Test.

Fast Detection of Mobile Replica Node Attacks in Wireless Sensor Networks
Using Sequential Hypothesis Testing



INTRODUCTION

ADVANCES in robotics have made it possible to develop a
variety of new architectures for autonomous wireless
networks of sensors. Mobile nodes, essentially small robots
with sensing, wireless communications, and movement
capabilities, are useful for tasks such as static sensor
deployment, adaptive sampling, ....etc

As sensor networks edge closer towards wide-spread deployment



security issues become a central concern. Sensor networks have been identified as being useful in a variety of domains to include the battlefield and perimeter defense. So far, much research has focused on making sensor networks feasible and useful, and has not concentrated on security.
We present a suite of security building blocks optimized for resource constrained environments and wireless communication. SPINS has tw ....etc
