The sensed information such as humidity, temperature, pressure, infrared images and noise are packed to send over the network. However, errors at the time of transmission may increas the risk of fault in information. Efficient energy consumption and reliable transmission in sensor networks are the main challenges. To achieve high reliability transmission there are two methods for sensor networks: Data redundancy and retransmission. In this article a reliable method of connection for packet retransmission, based on the correlation between data has been proposed. In this method, some parts of data way are considered as error zone. This method was evaluated using the OPNET simulator. Simulation results show that the proposed method can save energy and increase the lifetime of the sensor network.
