Wireless sensor network are used in various applications and fields which include military, environmental, health care, biological, home and other commercial applications. With the huge developments and advancements in the field of embedded systems and sensors technology, wireless sensor networks, which composed of several thousands of sensor nodes, which are capable of physical data sensing, processing and data transmission, have made a remarkable impact everywhere. In this paper we present an experimental model to be used for wireless sensor network investigation in order to improve the network performance parameters such as improving the life time of the nodes and optimizing the use of power energy.
