Abstract
In cognitive radio network, the activities of primary users will cause great influence on the stability of multiple hops routes between cognitive users. In this regard, a joint channel selection and routing protocol, termed as CSRP, is proposed to ensure route stability and reduce route latency between cognitive users. The channel availability based on historical information and the channel switching delay are used as the channel selection criteria to choose the end-to-end shortest route which possesses high data delivery probabilities and low delays. Besides, simulation results show that the proposed protocol has a better performance in terms of packet transmission delay and data delivery rate compared with the routing protocols based on delay (TDRP) and based on joint routing and channel allocation (PUB-JRCA).
Highlights
The wireless communication technology since 20th century has been developed rapidly and has brought great convenience for people’s life
The core idea is that cognitive user using a unique detection device automatically detects the spectrum state on the current environment to find the idle channel and, without interfering with primary users, choose an opportunity to access the channel to achieve the purpose of spectrum multiplexing, improving network transmission performance [3]
We propose a novel routing protocol CSRP with channel selection algorithm for cognitive radio network and, in the premise of ensuring routing stability, channel availability and switching delay are used as the selection criteria
