Abstract

Wireless sensor networks consist of many small nodes. Each node has a microprocessor, a radio chip, some sensors, and is usually battery powered which limits network lifetime. Applications of wireless sensor networks range from environmental monitoring and health-care to industrial automation and military surveillance. Since the nodes are battery powered and communication consumes more power than computation much of the research focuses on power efficient communication. One of the problems is however to measure the power consumption and communication quality. Simulation of sensor networks can greatly increase development speed and also be used for evaluating power consumption as well as communication quality. For application and system development, simulators can be used to test code functionality and find software bugs. For research experiments, simulators can be used to get easier access to fine grained results than corresponding real world experiments. One problem with simulators is
