“…According to this results, the omnidirectional scheme takes the longer time to deliver a packet, due to the higher probability of finding the channel busy. Further remarks on antenna complexity and practical feasibility of the proposed scheme can be found in a previous work of the authors [10].…”

Presently, wireless sensor networks most challenging applications are related to mobile sinks or even nodes, monitoring and intervening in critical areas. To this end, proper communications protocols design plays a crucial role in fulfilling user requirements.In the following, the benefits of adopting directive antennas, both in terms of energy saving and targets tracking are presented by integrating this feature into a novel MAC protocol (MD-STAR). Simulation results are also deeply provided, underlining higher performance of MD-STAR with respect to existing solutions, for different directive main lobe width and node density values.

“…Their proposed approach increases the network lifetime when the directional antenna is used only at the sink node. Manes et al in [32] also show that a MAC protocol using directional antennas reduces power consumption more than a MAC protocol that uses omnidirectional antennas. Additionally, in [33], it is shown that the network lifetime increases with the use of directional antennas by reducing the duty cycle.…”

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.

“…The upper level handles communications between the SNUs and the server using a custom binary protocol on top of a TCP layer. This level was designed and calibrated for real-time, bidirectional data exchange, in which periodic signaling messages are sent by both sides [ 9 ]. Since the sensor network necessitates a stable link, quick reconnection procedures for broken links were important.…”

“…Energy budget plays a key role in maintainability of the WSN [ 4 , 7 , 9 ]. In our case, this is made even more critical by the necessity to provide standalone operation with periodic maintenance intervals exceeding four months.…”

This paper describes a distributed point-source monitoring platform for gas level and leakage detection in hazardous environments. The platform, based on a wireless sensor network (WSN) architecture, is organised into sub-networks to be positioned in the plant’s critical areas; each sub-net includes a gateway unit wirelessly connected to the WSN nodes, hence providing an easily deployable, stand-alone infrastructure featuring a high degree of scalability and reconfigurability. Furthermore, the system provides automated calibration routines which can be accomplished by non-specialized maintenance operators without system reliability reduction issues. Internet connectivity is provided via TCP/IP over GPRS (Internet standard protocols over mobile networks) gateways at a one-minute sampling rate. Environmental and process data are forwarded to a remote server and made available to authenticated users through a user interface that provides data rendering in various formats and multi-sensor data fusion. The platform is able to provide real-time plant management with an effective; accurate tool for immediate warning in case of critical events.
