Wireless sensor network is the absolutely necessary infrastructure for the internet of things. Aiming at the energy storage and power control problem of nodes in internet of things, this paper analyzes detailedly some typical power control algorithms and its effects to network performance, and proposes a power control algorithm of nodes in internet of things based on vague sets. Use vague sets theory...
The biological Deoxyribonucleic acid (DNA) strand is found to be a promising computing unit. DNA computing is attracted as one method which gives us suitable answers for optimization problems. Proportional Integral Derivative (PID) control schemes have been widely used in industrial fields. Since the PID parameters have a great influence on the stability and performance of the control system, many...
The energy constraint bottleneck in the wireless sensor networks (WSN) exist objectively. To reduce energy consumption and ensure the Quality of Service (QoS) in data transmission, a method of solving the QoS multicast routing in WSN by quantum particle swarm optimization algorithm (QPSO). The algorithm is based on PSO, quantum-bit, principle of superposition and quantum gates. By the premise of avoiding...
Non-fragile guaranteed cost control for a class of T-S fuzzy system is studied. The concept of T-S fuzzy system is explained and the condition of robust stabilization is in the form of matrix inequality which can be converted to the LMIs. Then, non-fragile guaranteed cost control is applied to T-S fuzzy system. A sufficient condition for the existence of such non-fragile guaranteed cost controllers...
