Co-simulation of Mobile Wireless Networked Embedded Systems in Physical Environments

In English Embedded systems are becoming increasingly networked and aredeployed in application areas that require close interaction withtheir physical environment. Examples include distributed mobileagents and wireless sensor/actuator networks. The complexity ofthese applications make co-simulation a necessary tool during systemdevelopment. This paper presents a simulation environment thatfacilitates simulation of computer nodes and communication networksinteracting with the continuous-time dynamics of the real world.Features of the simulator include interrupthandling, task scheduling, wired and wireless communication, localclocks, dynamic voltage scaling, and battery-driven operation.Two simulation case studies are presented: a simple communicationscenario and a mobile robot soccer game.
