Research of an Adaptive Energy-Saving and Optimization Topology Control Technology for Heterogeneous Sensor Networks

In the Heterogeneous sensor networks, each be initial energy sensor node widespread in Heterogeneous wireless communication, the nodes in the process such as communications link heterogeneous phenomenon.In order to prolong the network life period, this paper proposes an Adaptive optimization heterogeneous wireless sensor network topology structure control algorithm (Adaptive VAP-ED) .The algorithm, based on data transmission experience of hop and between adjacent sensors, according to a jump communication distance geometry theory, combined with similar triangle concrete application of sensor nodes scene clumps, clusters operation are adaptive optimal control.Simulation experiments show that the algorithm can efficiently control the given data acquisition monitoring area all nodes network topology and greatly extend the life cycle of heterogeneous sensor network.
