Riadh Dhaou, Ryad Ben-El-Kezadri, Julien Fasson, Fabrice Arnal, Emmanuel Dubois, Patrick Gelard
2013 International Journal of Satellite Communications And Networking  
This paper proposes a generic scheme based on the Institute of Electrical and Electronics Engineers 802.21 standard to optimize handover and resource management in hybrid satellite-terrestrial networks  ...  First, we leverage the support of 802.21 in the terrestrial access network to shorten the path of the signaling messages towards the satellite resource manager.  ...  Ideally, the up handover should be perfectly synchronized with the reception of the satellite bursts. Finally, we plan to apply OHRM to other terrestrial technologies and satellite systems.  ...
