Wireless Sensor Networks

Abstract

Wireless sensor networks (WSNs) can be classified among the blazing domains of research in the recent era. WSNs have enormous day-to-day life real-time applications due their low priced, self-computing, powerful, autonomous small sensor nodes which have a small storage capacity, restricted non-removable non-rechargeable battery, and a restricted computational capacity. The applicability of WSNs are in almost all domains, like observing environmental conditions, human healthcare tracking systems, position tracking and monitoring, industry automation, process tracking and controlling, tracking and monitoring objects, mammal, human being, and control, and many more. This chapter briefly explores the basic concepts, components, network architecture, design issues, challenges, routing protocols, application domains, implemented applications, etc. in the field of WSNs. It also focuses on the performance evaluation parameters to check, analyze, diagnose, examine, and determine the performance of WSNs. At the end, the chapter concludes with the scope of research in the field of wireless sensor networks.
