ABSTRACT
There is a need to collect the environmental parameters from a remote location and send the collected data to base station for processing of the data. For this purpose, a wireless sensor network (WSN) is used, which is a network consisting of a number of sensors connected to a base station in order to collect the information of any environmental parameters. A wireless sensor network can be defined as a self-configured and infrastructure-less network that can be used for monitoring different physical and environmental parameters based on the type of usage and applications. Environmental parameters like pressure, temperature, etc. are collected by sensors that are sent from node to node to a mail location, termed a sink node, for observation, processing and analyzing. Thus, sink node acts like an interface between user data and network. The processed data can be collected from sink nodes through queries. Thus, a WSN network consists of hundreds to thousands of nodes connected in a form of network that communicate with each other using radio signals to process any information from a remote location to a base station for processing. The nodes are set using different types of topologies like star, mesh, hybrid, etc., depending upon the type of usage and structure needed.
