Location Privacy and Energy Preservation in Sensor Allocation Systems

The authors propose sensor-to-task assignments algorithms that take into account location privacy issues. Their solutions enable the network to choose the "Best" assignment of the available sensors to the tasks to maximize the utility of the network while preserving sensors' location privacy. They focus on preserving the sensors' locations during the assignment process in contrast to previous works, which considered location privacy while sensors are in operation. They also propose an energy-based algorithm that uses the remaining energy of a sensor as a factor to scale the distance between a sensor and a task such that sensors that have more energy appear to be closer than ones with less energy left.
