Uncertainty in Wireless Sensor Networks

Advances in sensor technology, wireless networking and in mobile devices are revolutionizing the ways that information from the physical world is collected and used. Wireless sensor networks deploying these technologies have had significant impacts on applications in a wide variety of fields including the military, science, industry, commerce, transportation and healthcare. Factors such as constraints of the sensing devices, the varying and potentially hostile environments where sensors are deployed, changing network topologies, unreliable communications, irregular radio patterns, etc. point to uncertainty as an inherent operational aspect of sensor networks.
