| Abstract: | Because of limited energy of nodes in wireless sensor networks. It is necessary to design an effective routing protocol and an algorithm of data fusion to save energy and extend the survival time of the networks. In order to solve the problem, the article proposes a novel improved data fusion algorithm based on TEEN. Some aspects have been improved, such as joining the energy factors in the process of cluster-heads selecting, improving the data periodic collection mechanism , using multi-hop communication between cluster heads and base station and selecting batch estimate data fusion algorithm based on the Kalman filter. The simulated result based on NS-2 network simulator shows that the improved TEEN protol prolongs the lifetime of sensor networks effectively. |
