Routing algorithms capable of providing quality of service (QoS) will play an important role in future communication networks. For the trajectory-based routing ( TBR), An effective method of en- coding trajectories into packets is proposed. The method uses a B-spline curve, which provides a lot of flexibility. The simulation results show that the performance of the proposed algorithms is im- proved significantly compared with the existing algorithm. 展开更多
