TL;DR: It is demonstrated that the proposed adaptive WiseMAC protocol is capable of providing higher energy efficiency for the low throughput applications in comparison to other existing sensor MAC protocols.
Abstract: MAC layer protocols play important role in wireless sensor networks to save energy and increase the lifetime of battery. In recent years, many MAC protocols are proposed to minimize the energy requirements. In this paper, we propose an adaptive WiseMAC protocol to further enhance the energy efficiency of wireless sensor networks as well as for variable traffic conditions. Proposed protocol incorporates dynamic duty cycle as well as adaptive contention window schemes. We have simulated the protocol in NS2 environment and checked the performance. It demonstrates that the proposed protocol is capable of providing higher energy efficiency for the low throughput applications in comparison to other existing sensor MAC protocols.

TL;DR: Results show that all component can communicate effectively which is vital to activate the require functionality to alert the user to perform good hand hygiene, it means SN-AHHS is activated when the user step into the facility.
Abstract: The implementation of Sensor Network is a vital area of research in achieving accurate data transfer for automated hand hygiene systems. Sensing devices is also called host or end systems, they provide a service to collate data and can access the internet. The investigation of the entire sensors which include Infrared, water, ultrasonic, distance and motion sensor are based on the Internet Protocol Stack. Internet Protocol Stack consist of five layers such as physical, link, network, transport and the application layer, these layers work together to transmit data across the network. Public building is considered vital to be protected from the spread of infection through poor hand hygiene. In this sense an automated system is required to encouraging people to mitigate the spread of infections in such environment. In this context, this paper proposes a Sensor Network Automated Hand Hygiene Systems in public building (SN-AHHS). Sensor Network Automated Hand Hygiene Systems was designed to prevent spread of infection occurring in public building facilities by prompting users. The designed system uses smart devices (sensors and actuators) for SN-AHHS system. Internet of Things (IoT) platform is employed to process and analyze the collected data from these smart devices in the facility. SN-AHHS has been tested and evaluated, the results show that all component can communicate effectively which is vital to activate the require functionality to alert the user to perform good hand hygiene, it means SN-AHHS is activated when the user step into the facility.

TL;DR: A Low-Power WSN Protocol with ADR and TP Hybrid Control is proposed in this paper to improve battery life significantly and the long-term testing results show that the nodes with the proposed algorithm can balance the communication quality and low power consumption simultaneously.
Abstract: Most Internet of Things (IoT) systems are based on the wireless sensor network (WSN) due to the reduction of the cable layout cost. However, the battery life of nodes is a key issue when the node is powered by a battery. A Low-Power WSN Protocol with ADR and TP Hybrid Control is proposed in this paper to improve battery life significantly. Besides, techniques including the Sub-1GHz star topology network with Time Division Multiple Access (TDMA), adaptive data rate (ADR), and transmission power control (TPC) are also used. The long-term testing results show that the nodes with the proposed algorithm can balance the communication quality and low power consumption simultaneously. The experimental results also show that the power consumption of the node with the algorithm was reduced by 38.46-54.44% compared with the control group. If using AAA battery with 1200 mAh, the node could run approximately 4.2 years with the proposed hybrid control algorithm with an acquisition period of under 5 s.

TL;DR: It is shown that WiseMAC can provide a significantly lower power consumption for the same delay than the power management protocol used in the IEEE 802.15.4 ZigBee standard.
Abstract: This work proposes wiseMAC(wireless sensor MAC) for the downlink of infrastructure wireless sensor networks. WiseMAC is a novel energy efficient medium access control protocol based on synchronized preamble sampling. The trade-off between power consumption and delay is analyzed, focusing on low traffic. WiseMAC is compared analytically with the power management protocol used in the IEEE 802.15.4 ZigBee standard. It is shown that WiseMAC can provide a significantly lower power consumption for the same delay.

TL;DR: The novelty in this protocol consists in exploiting the knowledge of the sampling schedule of one’s direct neighbors to use a wake-up preamble of minimized size, which allows not only to reduce the transmit and the receive power consumption, but also brings a drastic reduction of the energy wasted due to overhearing.
Abstract: WiseMAC is a medium access control protocol designed for wireless sensor networks. This protocol is based on non-persistent CSMA and uses the preamble sampling technique to minimize the power consumed when listening to an idle medium. The novelty in this protocol consists in exploiting the knowledge of the sampling schedule of one’s direct neighbors to use a wake-up preamble of minimized size. This scheme allows not only to reduce the transmit and the receive power consumption, but also brings a drastic reduction of the energy wasted due to overhearing. WiseMAC requires no set-up signalling, no network-wide synchronization and is adaptive to the traffic load. It presents an ultra-low power consumption in low traffic conditions and a high energy efficiency in high traffic conditions. The performance of the WiseMAC protocol is evaluated using simulations and mathematical analysis, and compared with S-MAC, T-MAC, CSMA/CA and an ideal protocol.

TL;DR: Predictive-Wakeup MAC is presented, a new energy-efficient MAC protocol based on asynchronous duty cycling that minimizes sensor node energy consumption by enabling senders to predict receiver wakeup times and introduces an on-demand prediction error correction mechanism that effectively addresses timing challenges such as unpredictable hardware and operating system delays and clock drift.
Abstract: This paper presents PW-MAC (Predictive-Wakeup MAC), a new energy-efficient MAC protocol based on asynchronous duty cycling. In PW-MAC, nodes each wake up to receive at randomized, asynchronous times. PW-MAC minimizes sensor node energy consumption by enabling senders to predict receiver wakeup times; to enable accurate predictions, PW-MAC introduces an on-demand prediction error correction mechanism that effectively addresses timing challenges such as unpredictable hardware and operating system delays and clock drift. PW-MAC also introduces an efficient prediction-based retransmission mechanism to achieve high energy efficiency even when wireless collisions occur and packets must be retransmitted. We evaluate PW-MAC on a testbed of MICAz motes and compare it to X-MAC, WiseMAC, and RI-MAC, three previous energy-efficient MAC protocols, under multiple concurrent multihop traffic flows and under hidden-terminal scenarios and scenarios in which nodes have wakeup schedule conflicts. In all experiments, PW-MAC significantly outperformed these other protocols. For example, evaluated on scenarios with 15 concurrent transceivers in the network, the average sender duty cycle for X-MAC, WiseMAC, and RI-MAC were all over 66%, while PW-MAC's average sender duty cycle was only 11%; the delivery latency for PW-MAC in these scenarios was less than 5% that for WiseMAC and X-MAC. In all experiments, PW-MAC maintained a delivery ratio of 100%.
