英文摘要： In this project, we studied network coding technologies for efficient packet routing in cognitive radio ad hoc networks. Main research completed include: (1) categorized the wireless packet retransmission problems(WPRTPs) into several classes, fully exploited the characteristics of these classes in the analysis, utilized the characteristics of Vandermonde matrix in analyzing perfect WPRPTs, and proposed an efficient scheme for perfect WPRTPs based on random network coding; (2) Proved the problem reduction theorem and proposed the reduction method for Imperfect WPRTPs, and then proposed an efficient scheme for Imperfect WPRPTs based divide-and-conquer approach; (3)Taking into consideration of main characteristics of cognitive radio networks, we proposed the conception of multi-channel WPRPTs (MC-WPRTPs), and then based on our previous results, packet retransmission schemes in different settings are proposed by transferring to some integral linear programming problems; (4) Proposed schemes for multi-hop multicast/broadcast packet dissemination application in cognitive radio networks; (5)Proposed several schemes for collaborative spectrum sensing and resource allocation in cognitive radio networks based on theoretical results including game theory, DS evidence theory, etc, the outage probability for several settings of collaborative relay networks were obtained as well. The above mentioned results buildup a solid foundation for further deepen and expand the research in future. The project proceeded following the plan very well. The typical results achieved so far include: 19 academic papers were published or accepted, including 4 papers in important international journals indexed by SCI, 1 papers have already been indexed by SCI, 11 papers were published in or accepted by Chinese journals such as Chinese Journal of Electronics, 7 papers have already been indexed by EI. Additionally, 3 patent applications were in treatment process. Furthermore, 1 academic book has been composed and will be published in a few months.
