—For the WAVE applications built on safety beacons, it is imperative that the neighboring vehicle information be collected as quickly and efficiently as possible. But the unreliability of broadcast transmission and the randomness of channel access in the IEEE 802.11p MAC hamper the collection process. Specifically , the process suffers from essentially a(More)
—Simultaneously utilizing multiple channels can be an effective countermeasure to the performance degradation stemming from high contention in the IEEE 802.11-based networks. This is especially true in multi-hop networks where spatial interference exacerbates the contention problem. Existing proposals use a special channel, a time window, or an orchestrated(More)
