Wireless Sensor Network (WSN) have been increasing dramatically in the recent years as they are used more & more in daily life. Medical, environmental and military sectors are some important areas that the recent developments have been applied in. In some cases, sensor networks are expected to be able to operate for a long period of time in standby and transmit the gathered data when required, as soon as possible. In this paper, the authors propose a cluster network. They design using Star topology. Because it is easy to implement & as compared to others it gives efficient result. Also in this growth of network can be easily done by increasing the number of nodes. They make three scenarios in it.
