SensGrid: modeling and simulation for wireless sensor grids
Grid computing technologies are emerging as the latest generation of distributed computing, as they allow the aggregation of resources that are geographically distributed over different locations. Since researchers need to conduct repeatable and controlled experiments, it is easier to use simulation as a means of studying complex scenarios. In this area, the GridSim simulation toolkit is a widely accepted option. We have designed and implemented a simulator of systems that integrates sensors and a grid. In particular, an extension of GridSim has been created in order to enable the execution of simulations in a way the users can perform queries on sensor networks. In this paper, we present the features of the system to be simulated, the modeling proposed, and the high-level user interfaces of the simulator. We also describe an experiment that demonstrates how our proposal works, which may well be helpful for the research community.
