This paper studies a kind of group consensus problem for fractional-order multi-agent system(MASs). For leaderless MASs, We propose a distributed consensus algorithm under a bipartite graph. Based on the given dynamics, the agents are divided into two groups, each group can reach a steady state value and the steady state values of the two groups are different. Simulation examples are presented to...
Kademlia is a widely successful Distributed Hash Table (DHT) implementation, better known for its use in the BitTorrent protocol. In this paper, we revisit its overlay management separately from the DHT operations to allow it to be used with other distributed abstractions by providing an accurate and consistent view of the k-closest nodes to any given identifier. We then present invariants that avoid...
Consensus control problem for a group of agents in a multi-agent networked system is considered. The agents are modeled by linear dynamical systems and the interconnection topology of agent's network is represented as a directed weighted graph. A decentralized approach to the synthesis of consensus control is proposed, including a synthesis of the local stabilizing controllers for each agent of networked...
The problem of industrial network application for the purpose of data transfer within permanent monitoring systems is being analyzed. This task is considered as essential within systems of critical action, for example transportation systems. Authors in present article suggest the new option on network arrangement and compare it with famous network “Lo-RaWAN” together with data regarding developed...
Failing to make use of multi-path advantages in data center networks (DCNs) has confined accessible resources and increased the possibility of congestion. In this paper, we have presented a new algorithm for traffic engineering (TE) in a modular mode. In the proposed algorithm, the less loaded paths for conduction of current are selected with regard to the present conditions as soon as a current is...
This paper compares the energy consumption used for communication in the special case of a wireless sensor network that is deployed linearly over a long distance to monitor assets such as transmission lines or pipelines. A model for energy consumption is developed based on a suitable network architecture for a linear wireless sensor network (WSN). Using the model, the energy consumption of networks...
The Low Voltage Power Line Communication (LVPLC) MAC protocols are an important influence factor to the network throughput. To solve the problem that the relatively low throughput due to the asymmetric PLC channel influence, we propose an improved adaptive p persistent CSMA protocol to optimize throughput for the finite loads in LVPLC accurate artificial cobweb network. This protocol reduces collision...
Aiming at providing united control of multi-domain optical networks orchestration, we design the Federated Platform based on Open Network Operating System (ONOS). Our implementation includes adding and extending modules in ONOS to provide the global view of multi-domain networks and support cross-domain end-to-end services by communicating with the individual domain controllers through RESTCONF protocol...
This paper studies the consensus problem of a first-order multi-agent system by using event-based strategy. For each agent, both of the control law and the triggering function utilize estimated combinational measurement, which is calculated based on the combinational measurement that sampled at the agent's event instant. The distributed triggering function is developed to compute these instants. Only...
This paper deals with the leader-following consensus problem for a class of second-order multi-agent systems with unknown Lipschitz nonlinear dynamics. Moreover, the control coefficients are assumed to be identical and bounded but unknown. The Nussbaum gain function technique is employed to deal with unknown the control coefficients. It is proved that the states of the multi-agent systems can achieve...
Adaptive consensus design problems for swarm systems with Lipschitz nonlinear dynamics are investigated. An adaptive consensus protocol based on state errors is proposed to obtain adaptive consensus. By using a state decomposition method, adaptive consensus problems of a swarm system are transformed into the asymptotic stabilization problems of a reduced-order subsystem. Then, the structure property...
This paper considers the containment control problem for second-order multi-agent systems in the presence of communication noise and dynamically switching topologies. The control protocol is proposed for containment control, where a positive time-varying gain is employed in the protocol to attenuate the effect of noises. The stability of the proposed containment control protocol is studied with the...
This study addresses the problem of distributed consensus for discrete-time networked multi-agent systems (NMASs) with communication delays in the transmission network. Different from existing techniques, the networked predictive control scheme is introduced to compensate for communication delays actively and overcome the difficulties induced by the delays. A distributed consensus protocol based on...
This paper proposes a distributed adaptive iterative learning control protocol for consensus problem of linearly parameterized multi-agent systems with imprecise communication topology structure. T-S fuzzy models are presented to describe the imprecise communication topology structure. The AILC protocols are designed with distributed initial-state learning and it is not essential to fix the initial...
Distributed formation control of Unmanned Aerial Vehicle (UAV) in three-dimensional space is discussed in this paper. In order to achieve a faster consensus seeking, a consensus-based cooperative formation control strategy with the tow-hop relay protocol is proposed. UAV's nonlinear kinetic model is transformed into linear model by feedback linearization and the original control inputs are also transformed...
In this paper, fully distributed time-varying formation tracking problem for general linear time-invariant (LTI) multi-agent systems is investigated by using an adaptive-based approach. The communication topology is a spanning tree in which a leader's output is available to only a subset of the agents (followers) among which the communication is undirected. The followers can form a time-varying formation...
This paper investigates the event-triggered consensus for linear continuous-time uncertain multi-agent systems. The parameter uncertainty is assumed to be time-varying but norm-bounded. An event-triggered consensus protocol is proposed based on the predictive method to make the multi-agent system achieve consensus without continuous communication among agents. A necessary and sufficient condition...
In this paper, we consider the privacy preserving problem of consensus protocol. First, we introduce a privacy preserving scheme, where each node produces and transmits a sequence of random values with their mean equaling to the node's initial state. We show that the network can reach average consensus with privacy preserving scheme, and provide a sufficient condition under which the initial state...
This paper addresses the distributed specified-time containment control problem for multi-agent systems with general linear dynamics. A novel class of distributed containment controller are developed. For a specific time in advance, the designed controller ensures the containment control of linear multi-agent systems if the undirected topology is connected. In particular, the settling time can be...
Robust adaptive time-varying formation control problems for high-order linear multi-agent systems with parameter uncertainties and external disturbances are investigated. Firstly, using the adaptive updating mechanism, a fully distributed time-varying formation control protocol is proposed. The protocol is determined by each agent in a fully distributed form and does not need any global information...
