A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. The main concept of this project is to reduce power while transmitting through zigbee. Here temperature and humidity sensors are used. After sensing it transmits the data to fusion center through zigbee. By finding the accurate distance of the node power is allocated. For that two algorithms are used Opportunistic Power Allocation (OPA) and Adjacent Correction Positioning (ACP). OPA algorithm can achieve three following process Minimization of distortion, Minimization of transmit power, enhance the network lifetime. It can be able to find the distance of the nodes and allocate the power but it is not accurate. RSSI in OPA cannot find the accurate position of the nodes so that it consumes more power. ACP algorithm finds the accurate position of the nodes and reduces the power when the data’s are transmitted through zigbee.
