ParkingMeter: balancing energy savings and service availability.

ABSTRACTVehicular networks offer service coverage for urban environments that would otherwise be too costly for infrastructure-based networks to provide. While many services have already been proposed based on collaboration between moving cars, the inclusion of parked cars in these systems extends their reach, coverage and stability. However, despite the presence of a large car battery, cars still suffer from limited energy availability when they are parked. In these diverse environments, many services may be offered and existing application-oriented energy management solutions fail to capture the complexity of optimizing energy for each individual service, while current service-oriented solutions fail to capture the interactions between services. In response, we propose ParkingMeter, an energy management framework that handles the provisioning of multiple services concurrently by fairly allocating energy to each service, guaranteeing the most effective energy utilization for the system. We demonstrate the effectiveness of ParkingMeter through simulation of three diverse services and the feasibility of the architecture through the evaluation of our prototype system.
