Location aware DHT

"Place Lab: Device Positioning Using Radio Beacons in the Wild" - is an application API which allows any wireless device to listen to fixed beacon provider for her position estimation. Leveraging this API with Peer could be helpful in making location aware DHTs. Prefix Hash Three (PHT) used Place lab in building location aware DHT. The case study from Sylvia decouples application developed from DHT. A good point to note for while most of applications demand refined and optimized overlay for its QoS and performance requirements.
