网络编码方法能够有效地提高间断连接无线网络的资源利用率，但编码节点的数量需要根据网络状态动态地调整。为有效提高网络资源利用率，提出一种带有编码节点动态管理的间断连接无线网络数据转发机制。节点根据当前网络状态，以分布式的方式确定最优化编码节点数量，进而，综合考虑社会属性及可用资源两方面因素，动态地选取编码节点，以较低的开销实现可靠数据转发。仿真结果表明所提出的机制充分利用了节点间的连接机会，提高了网络资源利用率。

The limited network resources can be utilized effectively by the network coding method in intermittent con-nectivity wireless network, but the number of coding nodes should be dynamically adjusted according to network status. To effectively improving the network resources utilization, a data forwarding mechanism based on dynamically managing coding nodes for intermittent connectivity wireless network was proposed. According to the estimated results of current network status, the optimal number of required coding nodes could be determined with the distributed manner. Further-more, the social property and available resources were considered for coding nodes selecting to achieve reliable data for-warding with the lower overhead. Results show that the connection opportunities between nodes can be exploited ade-quately by our mechanism;moreover, the utilization of network resources can be improved dramatically.
