重定向是认知用户建立通信链路的基本操作。在[5]中,我们提出了一种跳跃停留(JS)交会算法,该算法被证明具有整体最佳性能。在这项工作中,我们提出了一个增强的跳跃停留(EJS)算法。与JS相比,EJS在非对称模型下将最大交会时间(MTTR)和期望交会时间(E(TTR))的上界从O(P3)降低到O(P2),而在对称模型下保持MTTR和E(TTR)上界的阶数为O(P),P是大于信道总数的最小素数.
Rendezvous is a fundamental operation for cognitive users to establish communication links. In [5], we proposed a jump-stay (JS) rendezvous algorithm which was shown to have the overall best performance. In this work, we propose an enhanced jump-stay (EJS) algorithm. Compared with JS, EJS lowers the upper-bounds of both the maximum time-to-rendezvous (MTTR) and the expected time-to-rendezvous (E(TTR)) from O(P3) to O(P2) under the asymmetric model, while keeping the same order O(P) of upper-bounds of MTTR and E(TTR) under the symmetric mode, where P is the smallest prime number greater than the total number of channels.
