Packet Error Correction in Personal Area Networks

It is shown that redundancy may be introduced at packet level for any type of network that will allow networks themselves to self-correct information and to improve data reliability by several orders-of-magnitude. Modelling and simulation of packet error correction has used an example static Bluetooth personal area network, PAN containing mobile slave devices. A novel retransmission of selected corrupt packets was used for point-to-point communication. This resulted in three orders-of-magnitude improvement in packet error rate for frames of 16 packets and a transmission redundancy overhead of only 50%. Two different example communication routing schema are then suggested that allow all masters to be connected. Slaves or masters can communicate with all other Bluetooth devices using at least two independent paths. Redundant packet copies can then be routed. This shows a network itself can be used for the purpose of improving information reliability. This is a new idea
