Frequency-domain criterion on containment control for general linear multi-agent systems with time delay is studied under the directed network topology. A distributed protocol with time-invariant delay is proposed. When time-delay is an unknown constant, frequency-domain criterion on containment control of general linear multi-agent systems with delay is obtained, and an upper bound of delay is given...
Centralized botnets inherently suffer the single point of failure problem. To resolve this, botmasters are generally designed with peer-to-peer architecture to harden the botnet infrastructures. In the last several years, hybrid P2P botnets relying on peer-list exchange represent one of the emerging trends in advanced botnets. Although these botnets are immune to index poisoning, they are still vulnerable...
The additive-increase multiplicative-decrease MAC (AIMD-MAC) protocol is a distributed multi-access algorithm proposed in our earlier work and it is controlled by three parameters: the update cycle, the additive increase term and the multiplicative decrease factor. It was designed to exploit the multi-packet reception (MPR) capability in wireless networks. We describe the AIMD-MAC protocol and study...
Cooperative communications is a promising technique to improve high data-rate coverage in the future communications systems, the strategies about selection relays have a huge effect on the performance of system. In this letter, we study two strategies about adaptive selection relaying protocols with opportunistic relaying. Moreover, the asymptotic outage probability was derived. Results show that...
A new protocol for quantum broadcast channels based on the fully quantum Slepian-Wolf protocol is presented. The protocol yields an achievable rate region for entanglement-assisted transmission of quantum information through a quantum broadcast channel that can be considered the quantum analogue of Marton's region for classical broadcast channels. The protocol can be adapted to yield achievable rate...
Given an arbitrary deployment of sensor nodes, one fundamental design issue in wireless sensor networks (WSNs) is to connect the source nodes collecting sensing data to the sinks so that sensing data flows efficiently and reliably to the sinks. To facilitate such data collection, we require a path formation protocol that will determine multi-hop routes between source nodes and data sinks. We avoid...
Power consumption now becomes the most important challenges when design distributed wireless sensor networks (WSN). There are several limits in the process of designing a WSN, in which the lifetime of a network should be taken into consideration. The lifetime could depend on the battery device and the protocols as well. In this paper we introduce a new protocol which can do better in power management...
Resource management and optimization among autonomous spatial databases in a grid environment is always a challenge task. In this paper, we introduce a BDI Agent model for cooperating complex spatial query optimization task in a grid environment. Spatial query agents coordinate with spatial database resource agents using FIPA auction protocol for dynamic spatial query execution. The experiment showed...
The phenomenon of self-organization is pervasive in nature,where biological organisms efficiently self-organize unreliable and dynamically changing components to develop a wide diversity of functions. In addition, these biological organisms enjoy the desirable properties of robustness to the failure of individual components, adaptivity to changing conditions, and the lack of reliance on explicit central...
The cooperative task processing and resource management among autonomous and heterogeneous spatial database systems in a grid environment is a challenge work. In this paper, we propose a BDI agent framework to process spatial query and dynamically manage resource in a grid environment. The BDI rational engine and the FIPA Contract Net Interaction Protocol can help spatial query agents to dynamically...
