“…The QFSA‐MAC and QODA‐MAC are both designed to reduce interference and collisions for meeting the QoS requirements of smart grid applications. However, QFSA‐MAC is more efficient than the QODA‐MAC because directional antennas reduce the interference and allow parallel transmissions between the neighbors by increasing spatial reuse of the radio resources .…”

Summary Wireless sensor networks (WSNs) are the most commonly deployed technology in smart grid environments owing to their advantages including low cost and successful adoption in various harsh smart grid environments. However, providing the quality of service (QoS) requirements of smart grid applications with WSNs is difficult because of the power constraints of sensor nodes and unreliable wireless links. In order to meet the QoS requirements of smart grid applications using WSNs, in this paper, we first propose a QoS‐aware omnidirectional antenna‐based medium access control (QODA‐MAC). Then, in order to investigate the impact of using sectored antennas on meeting QoS requirements, we also propose another QoS‐aware four‐sectored antenna‐based MAC protocol (QFSA‐MAC). The aim of the proposed approaches is to increase channel utilization with efficient service differentiation considering traffic flows with different requirements as well as providing reliable and fast delivery of data. We measure the performance of QODA‐MAC and QFSA‐MAC by making extensive simulations and compare them with each other. The results show that QFSA‐MAC outperforms the QODA‐MAC protocol and satisfies QoS requirements of smart grid applications by achieving significant improvement in terms of latency, energy consumption and data delivery.

Wireless Mesh Networks (WMNs), which feature infrastructureless broadband network configurations, are attracting attention as an elemental technology when it comes to the extension of current WLAN infrastructures. State of the art solutions addressing WMNs usually assume the use of omnidirectional antennas.In this paper we evaluate the performance improvements obtained when using directional antennas. By using simulations, we analyze the gains in terms of throughput, delay and fairness, considering a grid network topology used to extend an infrastructure network. Simulation results show that by changing the type of antenna in use from omnidirectional to directional, the average throughput of a WMN can increase about 56% and the average network delay can be reduced by approximately 40%, without compromising fairness.

“…Furthermore, in recent years, directional antenna technology has been studied in 802.11‐based networks. The increased spatial reuse with the combination of extended transmission range is especially attractive for 802.11‐based mesh networks 6, 7. Regrettably, directional transmissions can also cause serious problems in a WMN environment, increasing the number of instances of the hidden terminal problem 8.…”

Wireless Mesh Networks (WMNs) have emerged recently as a technology for providing high-speed last mile connectivity in next-generation wireless networks. Several MAC protocols that exploit multiple channels and directional antennas have been proposed in the literature to increase the performance of WMNs. However, while these techniques can improve the wireless medium utilization by reducing radio interference and the impact of the exposed nodes problem, they can also exacerbate the hidden nodes problem. Therefore, efficient MAC protocols need to be carefully designed to fully exploit the features offered by multiple channels and directional antennas.In this paper we propose a novel Multi-Channel Power-Controlled Directional MAC protocol (MPCD-MAC) for nodes equipped with multiple network interfaces and directional antennas. MPCD-MAC uses the standard RTS-CTS-DATA-ACK exchange procedure. The novel difference is the transmission of the RTS and CTS packets in all directions on a separate control channel, while the DATA and ACK packets are transmitted only directionally on an available data channel at the minimum required power, taking into account the interference generated on already active connections.This solution spreads the information on wireless medium reservation (RTS/CTS) to the largest set of neighbors, while data transfers take place directionally on separate channels to increase spatial reuse. Furthermore, power control is used to limit the interference produced over active nodes.We measure the performance of MPCD-MAC by simulation of several realistic network scenarios, and we compare it with other approaches proposed in the literature. The results show that our scheme increases considerably both the total traffic accepted by the network and the fairness among competing connections.
