The automatic control theory plays an important role in modern industries. With the rapid development of the Internet and a variety of wireless networks, its application field has been becoming wider and wider. However, in the design of networking protocols, instead of utilizing the classical control theory, most software engineers favor open-loop control. In reality, closed-loop control may well...
This paper considers the second-order consensus problem of discrete-time multi-agent systems over fixed and undirected network topologies. A distributed consensus protocol utilizing the current and one-step delayed position information is proposed. It is interesting to found that second-order consensus in such a discrete-time multi-agent system cannot be ensured without any one-step delayed position...
Topology control is one of the most important energy-saving techniques used in wireless sensor networks. It has evolved into two dominant research directions: power control and sleep scheduling. Although many topology control algorithms and protocols are claimed to be highly energy-efficient, this is not necessarily the case in real systems due to various isolated considerations. In this paper, based...
Power control plays an important role in wireless communications. However, most existing power control protocols are not efficient enough to be applied in real ad hoc network systems. In this paper, we propose PIPC (Proportion-Integral Power Control), a novel closed-loop power control algorithm that can be used in conjunction with any routing protocol as long as the routing table of a node provides...
