In this paper, we present a bandwidth-efficient data reliability mechanism for Smart Grid Wide-Area Monitoring communication networks. Reliable transmission of data pack-ets, especially feedback control packets, is deemed a critical requirement. By sending multiple copies of data packets on node or edge disjoint paths, reliability can be achieved. However, this is inefficient in terms of bandwidth usage. We present a network-coding based algorithm that can reduce the bandwidth requirement while improving data reliability by combining multi-path transmissions and network-coding techniques. The performance of the mechanisms has been studied using discrete-event simulation models. The simulation results show that the proposed mechanism reduces the bandwidth requirement by 65-82% while achieving nearly 100% reliability, compared to existing multi-path redundancy mechanism. © 2013 IEEE.

Network coding based reliable and efficient data transfer for Smart Grid monitoring

2013 IEEE International Conference on Advanced Networks and Telecommunications Systems, ANTS 2013

In this paper, we present efficient data reliability mechanisms for a communication network supporting wide area monitoring applications in the electrical Smart Grid. Reliability of data packets, especially control packets, is deemed a critical requirement. Reliability can be achieved by sending multiple copies of the data packet on disjoint paths. However, this is inefficient in terms of bandwidth usage. In this paper, we present two algorithms for reliable data transfer that can handle single link and double link failures respectively. The proposed mechanisms reduce the bandwidth requirement while improving data reliability by combining multi-path transmissions and error coding techniques. The performance of the mechanisms has been studied using discrete-event simulation models. Our simulation results show that the proposed mechanism is able to reduce the bandwidth requirement by 30-54%. Also, there is a significant improvement in data reliability with values reaching close to 100%. © 2013 IEEE.

Reliable data transfer mechanisms for Smart Grid wide area monitoring networks

The future of the electrical power grid is the 'Smart Grid' that uses a combination of digital sensing and actuation technologies. For example, Phasor Measurement Units (PMU) can be used to accurately measure the quality of power and help improve the reliability and efficiency of the grid. A specially designed network architecture is required to transport the PMU data to the data processing systems. The NASPInet framework specifies requirements (such as latency and reliability) to be met for different types of applications that will process the PMU data. The objective of this paper is to analyze suitable network architectures that can meet all the requirements of NASPInet and thus be useful for the Smart Grid. An architecture based on the publish-subscribe paradigm and a distributed hash table technique for storing meta-data about the publishers is presented. This architecture is compared to GridStat, PSIRP and Source Specific Multicast approaches, using discrete event simulation models based on OMNET++. The delay performance of these systems has been studied for different network parameters. © 2012 IEEE.
