中文摘要： 城市中的人﹑车﹑房、便携信息设备、传感器等元素都可作为一个认知单元协同完成一个城市级别的计算﹑通信并构成城市计算环境。近些年随着城市计算环境下的认知单元种类、规模不断扩大，无线业务需求急剧膨胀，原有无线频谱分配政策已经难以满足实际需要。为解决无线频谱资源稀缺问题，深入提升认知无线电网络的性能，可将协作感知技术、协作传输技术等协作技术应用于认知无线电网络中，构建“协作认知无线电网络”。本项目对城市计算环境下的协作认知无线电网络若干开放性问题进行研究，包括：能量高效协作感知节点选择问题；协作感知系统的多目标协作联盟构建问题；协作多通道感知问题；联合通道分配与协作通信集合划分问题。本项目的开展对于进一步提升协作认知无线电网络性能，推动协作认知无线电网络的理论研究和实用化有重要意义。使得在未来城市计算环境下的用户都能够公平、高效地使用无线频谱资源，享受到便捷、环保、高质量的通信服务和智能信息服务。

英文摘要： The city is our home.The individuals, vehicles, houses, potable wireless devices and sensor can be used as a congnitive unit to complete a city-level calculation and communication and form an urban computing environment. Nowadays, with the ever-increasing number of the congnitive units and the emergence of diverse wireless devices, it has become challenging to still use the traditional fixed spectrum allocation strategy. In order to utilize rare spectrum resources efficiently and further exploit the performance of cognitive radio networks, cooperative technologies such as cooperative sensing and cooperative transmission can be adopted. Thus a new paradigm-cooperative cognitive radio networks has emerged. In this project proposal, we are motivated to investigate several open problems of cooperative cognitive radio networks: (1) meeting the requirement for the energy-efficient cooperative sensing application in cognitive radio networks; (2) multi-objective non-linear programming problem for cooperative sensing; (3) a relatively robust optimization model problem under the scenario where multi-channels are cooperatively sensed and used by multi-SUs; (4) a joint spectrum allocation and cooperation set partition problem. This project proposal investigates several open problems and provides theoretical optimization mod
