Abstract:
In the recent years, we have seen a clear trend in consumer devices being equipped with multiple radio interfaces such as GSM, UMTS, WiFi. These types of devices will soon be ubiquitous. Since radio frequency is a limited resource, the need for sharing and re-using a radio spectrum will be even more noticeable than before. Studies show that collaboration when allocating a radio spectrum will result in better network performance. This paper proposes a solution that identifies radio devices in a specific area. Starting from the identification of the location of possible interfering devices, better decisions can be made, prior and under spectrum allocation through cooperation. Our solution provides the location information in an overlay network without need for additional exchange of information messages. By storing the geographic location directly in the node- id, all members of the overlay network can extract the exact location of all known nodes. Using geocast, we show that the information provided can be used to optimize existing geocast mechanisms to identify devices. The result is an overlay-based enhanced spectrum allocation system, ObeSA.
