Abstract

In this paper we evaluate the delay and sensing performance of distributed cooperative sensing in wireless sensor networks assisting cognitive secondary operation. We propose a time division multiple access protocol to exchange sensing information among neighboring sensors, that is tunable in terms of sensing cooperation range and frequency reuse distance. Our evaluation shows that short frequency reuse distance may cause significant packet loss in the sensing aggregation process. This loss however affects mainly transmissions with less significant information, and therefore low delay aggregation with efficient spatial time division multiplexing is possible.
