In some real systems, e.g., distributed sensor networks, individual agents often need to form coalitions to accomplish complex tasks. Due to communication and computation constraints, it is infeasible for agents to directly interact with all other agents to form coalitions. Most previous coalition formation studies, however, overlooked this aspect. Those(More)
Recently, task allocation in multi-agent systems has been investigated by many researchers. Some researchers suggested to have a central controller which has a global view about the environment to allocate tasks. Although centralized control brings convenience during task allocation processes, it also has some obvious weaknesses. Firstly, a central(More)
The energy dispatch problem is a fundamental research issue in power distribution networks. With the growing complexity and dimensions of current distribution networks, there is an increasing need for intelligent and scalable mechanisms to facilitate energy dispatch in these networks. To this end, in this paper, we propose a multi-agent coalition(More)

Service composition is an important research problem in service computing systems, which combines simple and individual services into composite services to fulfill users’ complex requirements. Service composition usually consists of four stages, i.e., service discovery, candidate selection, service negotiation and task execution. In self-organising systems,(More)
A novel philosophy of secure mobile agent model which is based on trust model, risk evaluation and cryptography is proposed in this paper. Compared to current related research, our dynamic model can update in real time and is comprehensive for combining subjective and objective estimation. In addition, this model is broadly adaptive due to its flexibility.(More)
Traditional hierarchical intrusion detection systems have a central manager which attracts hackers to attack and might overload when there are too many client requests. To overcome these drawbacks, some researchers suggested to apply Peer-to-Peer approaches in intrusion detection. Most current Peer-to-Peer intrusion detection systems only allow hosts to(More)
This paper studies the phenomenon of the evolution of cooperation in distributed networks by using an iterated game. An iterated game in a distributed network is a multiple round game, where in each round, a player gains a payoff by playing a game with its neighbours and updates its action based on the actions and/or payoffs of its neighbours. The(More)
This paper presents a hybrid multi-agent framework with a Q-learning algorithm to support rapid restoration of power grid systems following catastrophic disturbances involving loss of generators. This framework integrates the advantages of both centralised and decentralised architectures to achieve accurate decision making and quick responses when potential(More)
