A STUDY OF WIRELESS SENSOR NETWORKS ARCHITECTURE &ITS PROTOCOLS

Abstract

Wireless sensor networks consist of individual nodes that are able to interact with the environment by sensing or controlling physical parameters. These nodes have to collaborate to fulfill their tasks. The nodes are interlinked together and byusing wireless links each node is able to communicate and collaborate with each other. An ad hoc network is a network that is setup, literally, for a specific purpose, to meet a quickly appearing communication need. The simplest example of an ad hoc network is perhaps a set ofcomputers connected together via cables to form a small network, like a few laptops in a meetingroom. In this example, the aspect ofself-configurationis crucial – the network is expected to workwithout manual management or configurationUsually, however, the notion of a MANET is associated with wireless communication and specifically wireless multichip communication; also, the name indicates the mobility of participating nodes as a typical ingredient. On the other hand, these mechanisms also have to generalize to awider range of applications lest a completefrom-scratch development and
implementation of a WSN becomes necessary for every individual application this would likely render WSNs as a technological concept economically infeasible
