Symbiotic Cognitive Relaying with mobile Secondary nodes in Cognitive Radio Networks
Abstract
In a Symbiotic Cognitive Relaying (SCR) scenario, the Secondary users(SU) nodes can act as multihop relays to assist the communication between Primary User(PU) nodes in the case of a weak direct link. In return, the SU nodes are incentivised with the right to carry out SU-SU communication using licensed PU band for a fixed amount of time, referred to as the 'Time Incentive'. Existing work on SCR is constrained to a fixed ad-hoc SU network. In this paper, we introduce mobility in SCR by considering mobile SU nodes while keeping the PU nodes fixed. This paper uses a specific mobility pattern and routing strategy for the SU nodes to propose theoretical bounds on the throughput and delay of PU-PU transmission. We derive analytically the least throughput and maximum delay possible in our model.
