Adaptive Optimization Topology Control for Heterogeneous Sensor Networks

This paper has focused on the optimization of topology control for heterogeneous energy-saving sensor networks. In the heterogeneous sensor networks, there is initial heterogeneous energy in each sensor node which produces isomerism such as heterogeneous link in the process of wireless communication. Compared with the traditional energy conservation optimum algorithm which doesn’t take fully consideration of the communication distance and the allocation of re-clustering after node failure, this paper proposes an network topology control algorithm with adaptive optimizing isomerism for wireless-sensors. In order to expand the life expectancy of network, this algorithm, firstly bases on hop-count of transmission data and the communication distance of adjacent sensors, and then does adaptive optimal control on clustering sensor nodes in specific environment, according to geometric principle of similar triangles. Simulation experiments have shown the improved algorithm can control network topology of all nodes in given data acquisition and monitoring area with high efficiency. Meanwhile, the life cycle of heterogeneous sensor network can be greatly expanded. Copyright © 2013 IFSA.
