Improved DTRA Protocol Based on Slot Schedule
Wang Wei · Jisuanji gongcheng · 2011
This paper proposes an improved Directional Transmission and Reception Algorithm(DTRA) named SDTRA protocol based on slot schedule.In the process of neighbor discovery stage,the protocol decreases the collision through sending time random delay.In the process of slot schedule stage,it adopts greedy edge coloring algorithm to control the time the node can use.The protocol can assure the QoS support through synchronous slot schedule algorithm.Simulation results show that the improved DTRA protocol is much better than DTRA protocol in neighbor discovery,time utility and throughput.
