“…Nevertheless, power consumption is an important line of research that has been discussed in several papers [15,16,17,18,19,20,21]. In particular, a MAC-level protocol customized to the LSN scenario is proposed in [15], while a TDMA-based scheduling algorithm for LSNs is discussed in [16]. Similarly, Toma et al [17] propose a HDLC protocol for LSNs based on a TDMA MAC scheme, relying on the IEEE 802.15.4 PHY layer, and compare its performances with the ones of similar, widely adopted protocols.…”

“…Finally, some other papers focus on identifying the ideal topology and placement scheme for sensor nodes to maximize energy efficiency [20], also adopting transmission range adjustment policies [21]. All these papers present interesting solutions to increase energy efficiency in WSNs, however, few of them focus on the use of duty-cycling policies [15]. Anyway, in these works, no solution is adopted to adapt the activation and de-activation times of the nodes according to the synchronization errors and delays due to clock offsets and inaccuracies.…”

In this paper, a pervasive monitoring system to be deployed in underground environments is presented. The system has been specifically designed for the so-called “Bottini”, i.e., the medieval aqueducts dug beneath the Centre of Siena, Italy. The results of a measurement campaign carried out in the deployment scenario show that the transmission range of LoRa (Long Range) technology is limited to a maximum of 200 m, thus, making the adoption of a classical star topology impossible. Hence, a Linear Sensor Network topology is proposed based on multi-hop LoRa chain-type communications. In this scenario, an ad-hoc transmission scheme is presented that optimally evaluates the wake-up time of all nodes with the aim of minimizing the average energy dissipation deriving from clock offsets. Numerical results show that the proposed wake-up time optimization leads in the best case to a 50% reduction in power dissipation with respect to a scheme that evaluates the wake-up time in a non-optimal way.

This paper presents a time division multiple access MAC protocol that is specifically designed for applications requiring periodic sensing of the sensor field. Numerical analysis is conducted to investigate the optimum transmission scheduling based on the signal to interferencenoise-ratio (SINR) for ground level propagation model applied on wireless chain topology. The optimised transmission schedule considers the SINR value to enable simultaneous transmission from multiple nodes. The most significant advantages of this approach are reduced delay and improve the Packet Received Ratio PRR. Simulation is performed to evaluate the proposed protocol for intelligent transport system applications. The simulation results validate the MAC protocol for a fixed chain topology compared with the similar protocols.

“…Other related works include P-MAC [5], X-MAC [6], RI-MAC [7] and LC-MAC [8], which provide various other improvements on S-MAC on different aspects such as traffic load. However most of them are specific to solutions for wireless sensor networks and may not be fully relevant to the wireless mesh networks.…”

Devices in wireless mesh networks are often supplied with limited power resources, while also running complex applications with high energy requirements, such as high quality video deliveries over the network. Reducing energy consumption is a key factor when designing a solution for such scenarios. Some existing energy-aware video delivery solutions have been proposed for sensor networks, but they do not consider possible movement of devices and most of them are deployed at one network layer only. This paper presents E-Mesh, an energy-aware cross-layer solution for high quality multimedia deliveries over wireless mesh networks. The core idea of E-Mesh is to save energy at mesh network devices by managing their sleep-periods in a more smart way, while also trying to maintain high multimedia delivery quality. E-Mesh includes an innovative MAC-layer scheme for mesh device sleep period management and an energy-aware extension of the Optimized Link State Routing algorithm (OLSR). Network Simulator 3 (NS-3) simulation results show how important energy savings are obtained by using E-Mesh in comparison with the case when IEEE 802.11s mesh standard is employed, while maintaining good video quality levels.
