Introduction

Wireless sensor networks are increasingly
prevalent (or at least that was the prevailing thought in 2002)
 Sensors are very resource-limited
(SmartDust)
– Slow communication links (10 kbps)
– Limited computing power (8-bit, 4 MHz)
– Limited memory and storage (512 bytes)
– Limited batter ....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 two secure building blocks: SNEP and ?TESLA SNEP provides the foll ....etc

Wireless Sensor Networks

A wireless sensor network consists of large Number Of Nodes.Large number of heterogeneous Sensor devices spread over a large field.They perform Wireless sensing and Data Networking. Group of sensors linked by wireless media to perform distributed sensing tasks
Each node has three components: sensing, processing, and communication. Networked sensors can continue to operate accurately in face of failure of individual sensors.Each sensor node operates autonomously with no central point of control in the network. E ....etc
