Abstract: Provided are a swarm control apparatus and an operating method thereof. In particular, a swarm control method, performed by the swarm control apparatus, includes: generating a first rule related to the swarm, based on an attribute of at least one node from among a plurality of nodes; sharing the generated first rule with the at least one node; forming the swarm including the at least one node, based on the shared first rule; detecting a change in the at least one node in the swarm; and changing the first rule to a second rule, based on the detected change.

Abstract: An apparatus and a method for packet error correction in packet-switched networks is provided. Message packets to be transmitted on a network are subdivided into k symbols over GF(q), and the symbols are then encoded by a symbol-level encoder into a codeword of n>k symbols over GF(q). The codeword is transmitted on the network in a plurality of network packets to a symbol-level decoder, which recovers any symbols lost or corrupted in transmission. Encoding at the symbol level increases the amount of data that can be recovered in any single correction operation. The efficiency of the decoding is also enhanced because the location of symbol errors can be determined prior to decoding.
