“…The authors of [8] suggests an adaptive MAC protocol based on S-MAC, named AC-MAC. Combining S-MAC and AC-MAC with Dynamic Power Management mechanism [10] suggests a new protocol called AC-MAC/DPM. In the mechanism of S-MAC, a node goes to sleep period when they have no data to send or receive.…”

“…AC-MAC calculates the number of new duty cycles according to sensors traffic load, and uses the number of packets queued at the MAC layer as an indication of the traffic load. Considering Ni be the number of packets queued at MAC layer for node i and R i be the weighted value, R i can be expressed as [10]:…”

Wireless Sensor Networks have limited resources with traditional data gathering techniques. One of the limitations of wireless sensor nodes is its inherent limited energy resource. Therefore, designing an effective wireless sensor network to maximizing the lifetime of sensor node in order to minimize maintenance and maximize overall system performance becomes important. In this article, we have outlined the design factors and challenges in sensor networks. Then, we describe several MAC layer and routing layer protocols proposed for sensor networks. In this paper, we propose an adaptive approach to find an optimal routing path from source to sink when the sensor nodes are deployed randomly deployed in a restricted service area with single sink. Our analysis says our approach reduces the message communication to find a optimal routing path. Hence, the network consumes less energy and increases the lifetime of the network.

“…Accordingly, many standards such as WirelessHART, WIA-PA, and ISA100.11a have been proposed [1][2][3][4][5][6][7]. More specifically, a dynamic power allocation policy for a wireless sensor network has been studied in [5] to improve the throughput and reduce energy consumption. In [6], authors investigated a strategy to set the time length in LEACH protocol to prolong the lifetime and increase throughput of wireless sensor network.…”

RF energy harvesting: an analysis of wireless sensor networks for reliable communication

In this paper, we consider a wireless energy harvesting network consisting of one hybrid access point (HAP) having multiple antennas, and multiple sensor nodes each equipped with a single antenna. In contrast to conventional uplink wireless networks, the sensor nodes in the considered network have no embedded energy supply. They need to recharge the energy from the wireless signals broadcasted by the HAP in order to communicate. Based on the point-to-point and multipoints-to-point model, we propose two medium access control protocols, namely harvesting at the header of timeslot (HHT) and harvesting at the dedicated timeslot (HDT), in which the sensor nodes harvest energy from the HAP in the downlink, and then transform its stored packet into bit streams to send to the HAP in the uplink. Considering a deadline for each packet, the cumulative distribution functions of packet transmission time of the proposed protocols are derived for the selection combining and maximal ratio combining (MRC) techniques at the HAP. Subsequently, analytical expressions for the packet timeout probability and system reliability are obtained to analyze the performance of proposed protocols. Analytical results are validated by numerical simulations. The impacts of the system parameters, such as energy harvesting efficiency coefficient, sensor positions, transmit signal-to-noise ratio, and the length of energy harvesting time on the packet timeout probability and the system reliability are extensively investigated. Our results show that the performance of the HDT protocol outperforms the one using the HHT protocol, and the HDT protocol with the MRC technique has the best performance and it can be a potential solution to enhance the reliability for wireless sensor networks.
