A reliable QoS-aware routing scheme for neighbor area network in smart grid

Abstract

A reliable bi-directional communication network is one of the key factors in smart grid (SG) to meet application requirements and improve energy efficiency. As a promising communication infrastructure, wireless mesh network (WMN) can provide high speed and cost-effect communication for SG. However, challenges remain to maintain high reliability and quality of service (QoS) when applying WMNs to SG. In this paper, we first propose a hybrid wireless mesh protocol (HWMP) based neighbor area network (NAN) QoSaware routing scheme, named HWMP-NQ, to meet the QoS requirements by applying an integrated routing metric to route decision with effective link condition probing and queue optimization. To further improve the reliability of the proposed HWMP-NQ, we present a multi-gateway backup routing scheme along with a routing reliability correction factor to mitigate the impact of routing oscillations. Finally, we evaluate the performances of the proposed schemes on NS3 simulator. Extensive simulations demonstrate that HWMP-NQ can distinguish different applications and satisfy the QoS requirements respectively, and also improve the average packet delivery ratio and throughput with a reduced routing overhead, even with a high failure rate of mesh nodes.

“…Other QoS routing solutions [7,10] guarantee the requirements of different SG service needs in the same communication network. The authors in Ref.…”

“…The authors in Ref. [7] first proposed allocating QoS resources called a multi-gateway backup network scheme to handle concurrent SG applications. Then they presented QoS-aware routing based on the air time cost metrics of different SG services.…”

“…Recent QoS studies in the SG focus on the routing problem aspect to satisfy the data requirements . The common approach in these studies is adapting an existing routing algorithm to a different environment, such as a wireless sensor network (WSN) to the SG by considering the SG QoS metrics in routing decision algorithms.…”

“…Besides, the new era of Internet of Things [11][12][13][14] is driving the development for Vehicular Ad hoc Networks and Vehicular Sensor Networks [15]. While wireless mesh networks (WMNs) receive extensive attention thanks to its adaptability and expandability, and it can provide high data-rate, low cost and reliable wireless transmission methods in various types of applications, such as disaster relief, military surveillance and smart grid [16]. WMNs often rely on the IEEE 802.11 standards to provide wireless broadband services.…”
