5Security in WSN
5.1 Introduction
Wireless sensor networks (WSNs) have earned popularity and acceptance at a very fast pace. Unlike traditional networks, a WSN has design and implementation constraints. Still, resource constraints like storage, power, and computational memory of WSNs did not prove deterrent to their implementation. In fact, this development has happened faster, sometimes leaving a host of issues unresolved. Despite this, WSNs are widely deployed because of their potential low cost solutions with negligible infrastructure to real-life applications. Currently WSNs are deployed for terrestrial [6], underground [4] [57] and underwater [5] [40] applications.
These different scenarios do not leave a single environment in which one ...
