In this paper, the authors are discussing on the basic concepts of wireless sensor networks, with the survey of some of the basic necessary of the wireless sensor networks. Since wireless sensor network consists of the many research oriented terms like resource utilization of the network it may be battery, memory, performance. And various methods of achieving the above terms like clustering, data aggregation, data compressing, etc. At last the main thing is about the sensor nodes which is used to sense light, temperature, pressure with of different size of hardware components like battery, type of communicating medium, memory, processor speed, etc.
