Packet loss in multi-hop wireless ad hoc networks is an important factor in network performance optimization. Typically, MAC frame collisions and queue overflow caused by MAC contentions and interference are the main reasons of packet loss. Recently, MAC frame collisions had been paid much attentions to in mitigating packet loss. Whereas, queue overflow among inter-flow has rarely attracted attentions...
Physical carrier sensing (PCS) is an effective mechanism to reduce the collision and interference caused by hidden terminals in wireless ad hoc networks, which allows nodes to be separated by a silent margin. However, potential simultaneous transmissions may be suppressed in this silent margin due to exposed terminal problem. As a consequence, PCS mechanism affects the network performance in two opposite...
