The use of a Comprehensive Identification Infrastructure in Enhancing the lifetime of Sensor Networks

Payam Salehi, Mohammad Ebrahim Shiri Ahmad Abadi


Regarding to the application of sensor networks, sensor nodes should be designed so that they are cheap and small. Therefore, the sensor nodes are severely in energy constraints. On the other hand, the increase in the operating time of sensor networks especially in military and environmental applications is a criterion in evaluating the performance of sensor networks. Thus, increasing the lifetime of sensor networks has permanently attracted attention of researchers. The use of a virtual backbone, as well as clustering methods has a significant impact on increasing the network lifetime. Thus, in this paper, we attempted to combine backbone composition-based methods and clustering methods in order to introduce a new method based on the use of convex clusters connected with lower power consumption for data collection in networks. Simulation results show that above mentioned approach has had a significant improvement in comparison with the clustering methods and techniques involved in making a backbone.
