%X A cross-layer neighborhood reservation mechanism with in-band signaling system(called NR-INSIGNIA) for Ad Hoc networks was proposed,considering the impact of channel contention at MAC layer.When a node reserved bandwidth for a QoS flow,corresponding bandwidth reservation would be reserved at all its neighboring nodes simultaneously to eliminate the negative impact on bandwidth reservation caused by channel contention.This cross-layer neighborhood reservation mechanism can provide a certain guarantee for the QoS bandwidth reservation.Compared with the original INSIGNIA without neighborhood reservation,simulation results show that NR-INSIGNIA system can significantly improve the reserved packet ratio,packet delivery ratio and end-to-end delay of QoS flows.
