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...
The coal mine laneway is a kind of limited and changeable space with bend and embranchment in a longitudinal way. Its complicate environmental condition influences the connectivity, coverage, the packet loss rate and energy consumption of the wireless sensor networks. To construct the real system of wireless sensor networks for mine working environment, this paper proposes a clustering-based chain-type...
This paper presents a mathematical framework for the evaluation of the performance of proactive and reactive routing protocols in mobile ad hoc networks (MANETs). This unified framework provides a parametric view of protocol performance, which in turn provides a deeper insight into protocol operations and reveals the compounding and interacting effects of protocol logic and network parameters. The...
We present a mathematical framework for the performance evaluation of proactive and reactive routing protocols operating in mobile ad hoc networks (MANETs). The model captures the functionality of the routing protocols together with the characterization of the performance of the medium access control protocol (MAC). It reveals the interplay between the protocol functionality and network parameters,...
In mobile ad hoc networks (MANETs), nodes mobility causes network topologies to change dynamically over time, which complicates important tasks such as broadcasting and routing. Neighborhood tracking is a task to determine the neighborhood local view of a mobile node in time which can facilitate the forwarding decision in the design of network protocols. In this paper, we propose a predictive synchronization...
