A Review Paper on Wireless Sensor Networks

Abstract

Wireless sensor networks are in use from the past few years and they involve deploying a large number of small nodes. A wireless sensor network consists of hundreds or thousands of low cost nodes which could either have a fixed location or randomly deployed to monitor the environment. Basically wireless sensor networking is used for monitoring the physical conditions such as weather conditions, regularity of temperature, different kinds of vibrations and also deals in the field of technology related to sound. The key evaluation metrics for wireless sensor networks are lifetime, coverage, cost and ease of deployment, response time, temporal accuracy, security, and effective sample rate. This paper provides review of various researches performed in the field of wireless sensor networks.
