“…We have compared our model against B-MAC, X-MAC, WiseMAC, and ZigBeee. The input parameters for the simulation work mentioned in Tables 7 and 8 are taken from [9][10][11]15,23]. Average power consumption and delay for the proposed MAC protocol are calculated.…”

“…An additional ultra-low power receiver is attached to the sensor nodes that can help save a significant amount of power by minimizing the idle listen period for the main radio. Out-of-band radio mechanism has been proposed for sensor networks to minimize power consumption [4,5,[12][13][14][15]. All of these works use an extra radio channel for waking up the sensor devices.…”

Applications of wearable and implanted wireless sensor devices are hot research area. A specialized field called the body area networks (BAN) has emerged to support this area. Managing and controlling such a network is a challenging task. An efficient media access control (MAC) protocol to handle proper management of media access can considerably improve the performance of such a network. Power consumption and delay are major concerns for MAC protocols in a BAN. Low cost wakeup radio module attached with sensor devices can help reduce power consumption and prolong the network lifetime by reducing idle state power consumption and increasing sleep time of a BAN node. In this article, we propose a new MAC protocol for BAN using out of band (on-demand) wakeup radio through a centralized and coordinated external wakeup mechanism. We have compared our method against some existing MAC protocols. Our method is found to be efficient in terms of power consumption and delay.

“…In order to achieve the low-power operation and short communication delay required for battery powered WLAN devices, wake-up receivers were proposed in [11][12][13][14]. The wake-up receiver is a simple structured receiver which detects on-off keying (OOK) signals, enabling low-power operation and short transmission delay, simultaneously.…”

Featured Application: IoT devices with wireless LAN (WLAN) communication.Abstract: In this paper, we propose a delay-and power-efficient, multi-user, low-power wireless local area network (WLAN) communication scheme for Internet of Things (IoT) WLAN devices. Extremely low-power operation is one of the key requirements of emerging IoT devices. However, the current duty-cycle-based power saving approach may incur large access delay times owing to the trade-offs between the power consumption and the access delay. In order to reduce this delay and enhance the power-saving performance, wake-up receiver-based schemes have been proposed. However, because wake-up receiver-based schemes do not consider multiuser operation in dense communication environments, large delays are inevitable in the case of multiuser operation. In order to provide extremely low-power operation and under 1-mW standby power with reduced delay, we employed the optimized multiuser transmission scheduling of IEEE 802.11ax in the proposed scheme and proper enhanced distributed channel access (EDCA) parameter settings. This is with the aim to reduce the delay caused by long wake-up times, and to avoid collisions caused by simultaneous transmission in uplink multiuser scenario. By using the proposed scheme, simultaneous IoT communication with multiple mobile IoT devices is possible while providing low-power operation. Simulation results verified the outstanding delay performance of the proposed scheme.

“…This costs tag energy, which means lowering of the tag battery life time. Various solutions for wake-up radios have been published [1][2][3][4][5]. They suffer from difficulties like low receiving sensitivity resulting in short reading range, awakening due to false signals, need of cyclic synchronizing, and need for a more complex transceiver.…”

In this paper we present a Radio Frequency Identification (RFID) protocol used to wake up and extract the ID of every tag (or a subset thereof) within reach of a reader in an active backscatter RFID system. We also study the effect on tag energy cost and read-out delay incurred when using the protocol, which is based on a frequency binary tree. Simulations show that, when using the 2.45 GHz ISM band, more than 1500 tags can be read per second. With a population of 1000 tags, the average read-out delay is 319 ms, and the expected lifetime of the RFID tags is estimated to be more than 2.5 years, even in a scenario when they are read out very often.
