通过采用不同的检测技术，车辆自组织网络（VANets）中的车辆能够收集各种信息，如道路交通和环境信息，然后将它们传输到感兴趣的实体。VANets中的数据收集被认为是一个有趣的应用程序，旨在提供更安全，更高效，更舒适的驾驶。在之前的研究[8]中，我们提出了一种鲁棒集群数据收集协议（CDGP），该协议使用具有重传机制的动态空分多址（D-SDMA）技术。然而，考虑到大量未使用的时隙，CDGP提供低收集效率，这些时隙在车辆到车辆通信（V2 V）中被浪费。在本文中，我们提出了一种新的数据收集协议，它提高了数据收集效率，通过使用增强的动态SDMA技术。仿真结果表明，该协议提高了数据采集效率，提供了可靠的数据采集。
By adopting different detection technologies, vehicles in Vehicular Ad-hoc Networks (VANets) are able to collect various kinds of information, like road traffic and environmental information, then, to transmit them to interested entities. Data collection in VANets is considered as an interesting application which aims at providing a safer, more efficient and more comfortable driving. In a previous study [8] we have proposed a Robust Clustered Data Gathering Protocol (CDGP), by using a Dynamic Space Division Multiple Access (D-SDMA) technique with a retransmission mechanism. However, CDGP provides a low collection efficiency given the large number of unused slots, which are wasted in a vehicle-to-vehicle communication (V2V). In this paper, we propose a new data collection protocol, which improves the data collection efficiency by using an enhanced Dynamic SDMA technique. Through simulation results we show that our new protocol enhances data collection efficiency and provides a reliable data collection.
