“…According to this algorithm each node, thanks to a distance-vector algorithm, knows the distance from the Internet through each path in the Mesh network, and forwards packets, in a round-robin fashion, through all the paths having the same minimum cost to reach the Internet, whatever the destination Gateway node. The distance-vector multipath network-balancing routing algorithm is used for two reasons: first it is able to reduce delay [25,35,36]; secondly, thanks to its multipath peculiarity, it increases the robustness of the architecture to external attacks and interceptions. In fact, if a path is shielded (maliciously or not), or its quality is temporally degraded, all the packets flowing through it are lost; however, the application of the multipath network-balancing routing algorithm guarantees that a high percentage of packets are able to reach the Video Decoder block, and therefore frames can be decoded, by applying an error concealment video decoding algorithm [37][38][39].…”
