Intermittently connected Mobile Cognitive Radio ad hoc Networks (IMCRNs) are promising wireless networks in which mobile unlicensed nodes use their temporarily available contacts and vacant licensed channels for end-to-end message delivery. In this paper, the authors propose Biological Foraging-inspired Communication (BFC) algorithm for the energy-efficient and spectrum-aware communication requirements in IMCRNs. BFC is based on two profitability measures called Relay Selection Profitability (RSP) and Channel Selection Profitability (CSP). RSP and CSP provide an autonomous decision-making mechanism that does not need any a priori information on node mobility and spectrum availability patterns.
