Other Abstract

Due to the high spectrum dynamics of cognitive radio sensor networks, traditional routing protocols have the drawbacks of poor timeliness and high energy consumption. To address the issue, this paper for the first time proposes an opportunistic forwarding based routing (OFBR) protocol for cognitive radio sensor networks. The novelty of the OFBR protocol lies in the combination of the short preamble sampling and the opportunistic forwarding. Besides, a cognitive real-time forwarding condition is designed with the consideration of protecting primary users and the forwarding delay. The OFBR protocol can effectively reduce the overhearing and duty cycles of cognitive sensors by short preamble sampling, and guarantee the real-time and reliable transmission while protecting primary users based on the cognitive real-time forwarding condition. Meanwhile, the OFBR protocol is a distributed routing protocol in which only local information is required in the routing process of data, and its routing overhead is thus reduced significantly. Extensive simulations show that the OFBR protocol obviously outperforms traditional routing protocols in the aspects of energy consumption and latency.
