“…When it receives the notification on a frame incoming on the second radio module, it activates the first radio module and is able to receive the frame. Examples of on-demand wake-up protocols are DW-MAC [16] and [17]. The main drawbacks of these protocols are the use of two radio modules (which increases the cost of the sensor nodes), as well as the energy consumption of the second radio module.…”

“…This mechanism can be initiated by the sender (using a preamble, such as in B-MAC [10] or in [11], [12]) or by the receiver (such as in RI-MAC [13], PW-MAC [14], HKMAC [15]). The nodes can also start their activities using an on-demand wake-up (such as in DW-MAC [16] or in [17]), a scheduled wake-up (as in [18], [19]) or a random wake-up (as in RAW [20] and [21]). …”

Abstract-In the past few years, energy conservation has been the main focus of researchers working on wireless sensor networks. One of the main technique to save energy is to deactivate periodically the radio module of sensor nodes: nodes alternate periods of activity and periods of inactivity, which is referred to as their duty-cycle. In this paper, we focus on asynchronous dutycycle mechanisms, as these mechanisms are usually simple, do not require time synchronization and support network changes. We propose an asynchronous MAC protocol based on blind rendez-vous and random wake-up. Our protocol is based on a modification of the IEEE 802.15.4 standard, where activities start at a random time within each activity cycle. Our simulations show that our protocol can achieve a good performance under various scenarios, for small duty cycles (ranging from 0.1% to 5%).

“…Schedule-based asynchronous duty cycling [16,17] requires two nodes to have overlapping active time. Another asynchronous method is detecting the preamble transmission [18][19][20] or wake-up signal [21,22]. The burden of extra energy expenditure lies on the transmitter, which must remain active until it receives the beacon from the intended receiver.…”

Wireless sensor networks for forest monitoring are typically deployed in fields in which manual intervention cannot be easily accessed. An interesting approach to extending the lifetime of sensor nodes is the use of energy harvested from the environment. Design constraints are application-dependent and based on the monitored environment in which the energy harvesting takes place. To reduce energy consumption, we designed a power management scheme that combines dynamic duty cycle scheduling at the network layer to plan node duty time. The dynamic duty cycle scheduling is realized based on a tier structure in which the network is concentrically organized around the sink node. In addition, the multi-paths preserved in the tier structure can be used to deliver residual packets when a path failure occurs. Experimental results show that the proposed method has a better performance.

“…Current research, into energy efficiency in sensor networks, puts the radio in sleep mode when there is no traffic to reduce energy consumption. These works can be classified into two main categories: (1) MAC protocols [2][3][4][5][6]; and (2) wake-up radios [6][7][8][9][10][11][12][13][14].…”

“…Event-driven wake-up radios provide an opportunity to solve idle listening. Previously published wake-up radios are low power with low sensitivity [6][7][8][9][10][11][12][13][14]. They provide extremely low energy consumption at the cost of shorter read range than the data radio [15].…”

Most of the published wake-up radios propose low energy design at the expense of reduced radio range, which means that they require an increased deployment density of sensor networks. In this article, we introduce a design of a high sensitivity 916.5 MHz wake-up radio using low data rate and forward error correction (FEC). It improves the sensitivity, up to -122 dBm at a data rate 370 bit/s. It achieves up to 13 dB of coding gain with symbol error rate (SER) 10 -2 , and up to 4 times the range of the data radio, rendering it more suitable to sensor networks. Our design can receive wake-up signal reliably from any IEEE 802.15.4 transmitter and achieves a low packet error rate (PER) 0.0159 at SNR 4 dB. Furthermore, our design encodes the node ID into a wake-up signal to avoid waking up the undesired nodes.
