A reconstruction and local optimization algorithm for an internet-based broadcast network for augmentation information of satellite navigation system
چکیده انگلیسی

Internet-based broadcast technology is one of the important compensation of geostationary orbit (GEO) satellite method to broadcast the augmentation information of satellite navigation system. Using application layer multicast (ALM) and peer to peer (P2P) technology is shown to be efficient technologies to build the broadcast network. However, most of the users in broadcast network has the characteristics of mobility. Therefore, it is a big challenge to handle the dynamic situation for broadcast network, in which the nodes enter and leave the network continually. In this paper, a novel reconstruction algorithm is proposed, and meanwhile, the local optimization mechanism is also investigated for broadcast network. Extensive simulations have been done to evaluate the performance, and the results show that the algorithm achieves better performance comparing with existing reconstruction algorithms.
