Abstract
Wireless sensor networks provide the smallest and cheapest form of wireless communicating and computing devices due to the advances in Processor, memory and radio technology. These wireless sensor networks pose significantly different design, implementation, and deployment challenges. In this project, I present a simulation of the wireless sensor network for paging applications. These pagers can provide small data transfer and can be used to transfer small pieces of information between themselves. A pager is a wireless sensor mote wh ....etc

CHAPTER1
INTRODUCTION
Motes are tiny, self-contained, battery-powered computers with radio links, which enable them to communicate and exchange data with one another, and to self-organize into adhoc networks. The core of a mote is a small, low-cost; low-power computer. The computer monitors one or more sensors. Motes package together into a circuit board with networking and application software; interfaces to sensors that can detect changes in temperature, pressure, moisture, light, sound, or magnetism; and a wire ....etc

WISENET is a wireless sensor network that monitors the environmental conditions such as light, temperature, and humidity. This network is comprised of nodes called motes that form an ad-hoc network to transmit this data to a computer that function as a server. The server stores the data in a database where it can later be retrieved and analyzed via a web-based interface. The network works successfully with an implementation of one sensor mote. ....etc

Abstract:
SECURE DATA COLLECTION IN WIRELESS SENSOR NETWORKS USING RANDOMIZED DISPERSIVE ROUTES

Compromised-node and denial-of-service are two key attacks in wireless sensor networks (WSNs). In this paper, we study routing mechanisms that circumvent (bypass) black holes formed by these attacks.We argue that existing multi-path routing approaches are vulnerable to such attacks, mainly due to their deterministic nature. So once an adversary acquires the routing algorithm, it can compute t ....etc

Abstract—Sensor networks have their own distinguishing characteristics that set them apart from other types of networks. Several techniques have been proposed in the literature to address some of the fundamental problems faced by a sensor network design. Most of the proposed techniques attempt to solve one problem in isolation from the others; hence, protocol designers have to face the same common challenges again and again. This, in turn, has a direct impact on the complexity of the protocols and on energy consumption. Instead of using this ....etc

Wireless Sensor Networks

Technology Overview


The individual nodes that constitute a wireless sensor network are generally small in size and use power-efficient batteries to extend their operational longevity. Depending on its function, each node has a sensor board that facilitates the detection and measurement of heat, vibrations, air-pressure and magnetic fields (among other things). The motes developed at UC Berkeley are a typical example of such devices. Motes h ....etc
