The effectiveness of Unmanned Aerial Vehicles (UAVs) is being increased to reduce the cost and risk of a mission [Doherty et al. 2000]. Since the advent of small sized but high performance UAVs, the use of a group of UAVs for performing a joint mission is of major interest. However, the development of a UAV is expensive, and a small error in automatic(More)
The paper studies two closely related problems: how to support efficient message passing in large-scale agent systems given that agents are mobile, and how to facilitate the discovery of service agents in an open environment where agents may enter and leave. The Actor Architecture has been designed to study simulations of large-scale agent systems where(More)
Agent-based simulations are an essential tool in analyzing the behavior of real-world systems. Agent-based distributed simulations can be a useful in addressing the scale and complexity of such simulations. Because agents in such simulations intensively communicate with each other to perform their shared tasks, performance of the simulation is strongly(More)
In CCN (Content-Centric Networking), one request retrieves at most one data packet. Although the design intent of such rule is to maintain flow balance across the network, it may cause significant underutilization of Data downlink, especially in networks with asymmetric up/down link speed such as cellular networks. This paper describes an adaptive flow(More)
 In the dynamic distributed task assignment (DDTA) problem, a team of agents is required to accomplish a set of tasks while maximizing the overall team utility. An effective solution to this problem needs to address two closely related questions: first, how to find a near-optimal assignment from agents to tasks under resource constraints, and second, how(More)
Content-centric networking (CCN) is a new networking paradigm to resolve the data traffic explosion problem of the Internet caused by rapid increase in file sharing and video streaming traffic. Networks with CCN avoid delivery of the same contents on one link as many times as they are requested, as contents can be stored and transferred by the cache of CCN(More)
