Data dissemination in wireless broadcast channels: Network coding versus cooperation

Ivana Stojanovic, Zeyu Wu, Masoud Sharif, David Starobinski
2009 IEEE Transactions on Wireless Communications  
Network coding and cooperative diversity have each extensively been explored in the literature as a means to substantially improve the performance of wireless networks.  ...  We show that if K is fixed, cooperation outperforms network coding, in the sense that the expected delay is proportional to K (and thus within a constant factor of the optimal delay) in the former case  ...  In wireless networks, network coding has been proposed for disseminating information to all receivers [3] and has been shown to provide excellent delay performance compared to round-robin scheduling,  ...

A Cooperative and Reliable RSU-assisted IEEE 802.11p-based Multi-channel MAC Protocol for VANETs

VanDung Nguyen, Tran Trong Khanh, Thant Zin Oo, Nguyen H. Tran, Eui-Nam Huh, Choong Seon Hong
2019 IEEE Access  
This study proposes a cooperative and reliable RSU-assisted IEEE 802.11p-based multi-channel MAC protocol for VANETs, called RAM.  ...  Unlike other types of networks, VANETs suffer from rapid changes in topology, resulting in frequent network disconnections caused by the high mobility of nodes.  ...  First, periodic packets perform cooperative vehicle collision avoidance. Each vehicle updates and disseminates its status via a periodic beacon broadcast.  ...
