摘要：In wireless sensor networks, a host may exhaust its power or move away without giving any notice to its cooperative nodes, causing changes in network topology, and thus, these changes may significantly degrade the performance. The key challenge in the design of wireless sensor networks is maximizing their lifetime. Since, how to prolong the lifetime of wireless sensor networks is an important issue in designing environmental monitoring applications. A technique is proposed to evaluate the node lifetime prediction and the link lifetime prediction utilizing the dynamic nature. During data gathering, sensors have the ability to perform in network aggregation of data packets en-route to the base station. RNG is a sparse connected overlay network which is defined based on local information at each node, which includes distance to each neighbor. Each sensor node predicts the values of the data to be sensed according to its recorded historical information. When getting the sensory data, the node compares it with the predicted data. The simulation results show that the proposed technique outperforms previous methods to maximize network lifetime.
