large number of other nodes‚ they have the ability to measure a given physical environment in great detail. Thus‚ a sensor network can be described as a collection of sensor nodes which co-ordinate to perform some specific action. Unlike traditional networks‚ sensor networks depend on dense deployment and co-ordination to carry out their tasks. Previously‚ sensor networks consisted of small number of sensor nodes that were wired to a central processing station. However‚ nowadays‚ the focus is
