This article presents current research work on the development of BEBS (BIONETS Economic and Business Simulation Model). This model is used to illustrate how in pervasive agent-based networks dynamic agents engage in distributed mobile communication exchanges that carry a potential, non-quantified value to be determined. This value can be monetised either as advertisement or as share of revenue profit for an external content or service provider wishing to distribute information over the network. The strength of the simulation model is to enable different ways in which the value of communication events can be quantified and that are not normally considered in conventional business approaches. Our simulation can therefore facilitate the exploration and development of alternative business models based on heterodox economic perspectives such as the economics of sharing, gift economy, and economic sociology applied to mobile networks.
With the emergence of large-scale storage systems that separate metadata management from file read/write operations, and with requests targetting metadata account for over 80% of the total number of I/O requests, meta...

The dynamic management of load in large-scale distributed systems is essential for the performance of simulations due to the influence that computing capacity and work load have on execution time. The High Level Architecture (HLA) was designed with the purpose of providing management services in order to organize distributed simulations, but the framework does not offer tools for controlling load imbalances of distributed simulations. In order to provide a generic solution for the simulation load imbalances, many approaches have been proposed. These schemes are limited to solve balancing issues regarding specific simulation or environment characteristics. With focus on balancing the computational load specially for HLA-based simulations, an approach have been previously proposed based on a centralized method, but this solution performs load re-distributions based on a central element, introducing global synchronization in the system. Therefore, avoiding the issues caused by centralization, a distributed, hierarchical balancing design is proposed to dynamically organize the load through three phases: monitoring, redistribution, and migration. The proposed scheme addresses improvement of fault tolerance, decrease of balancing overhead, and reduction of delays and bottlenecks, while exhibiting performance similar to the centralized approach in the experiments.
We foresee the need for dynamically clustering nodes in Wireless Sensor Networks (WSNs) according to a multitude of disparate co-existing contexts. To this end, we propose a distributed, low-overhead context-aware clu...

Networks have gotten bigger recently, and users have a more difficult time finding the information that they want. The use of mobile agents to help users effectively retrieve information has garnered a lot of attention. In this paper, we propose an agent control method for time constrained information retrieval. We pay attention to the highest score that agents have previously gotten and control the agent to expect at least a better score. Using computer simulations, we confirmed that our control method gave the best im- provement over the whole network while reducing the over- all variance. From these results, we can say that our con- trol method improves the quality of information retrieved by the agent.
