Industrial Wireless Sensor Networks (IWSNs) adopted for wireless factory automation demand highly reliable, robust and delay sensitive communications over an interference prone and harsh channel conditions existing in factory environments. IEEE 802.15.4e Low Latency Deterministic Network (LLDN) mode is the latest in IWSN standards which attempt to satisfy these requirements assuming controlled RF...
An important issue in optical burst switched (OBS) networks is the loss of bursts at intermediate nodes due to contention. Such contention losses, usually do not mean a situation of congestion. In this paper, we propose for the first time, a loss recovery mechanism using Forward Error Correction (FEC) to recover bursts that are lost due to contention. Using FEC, for every K bursts, N−K redundant bursts...
