“…Nodes are deployed in equal intervals of 200 m. We perform simulations over 33000 seconds. We use the static routing schemes to eliminate the effects of routing algorithms as those in [12]. In the chain topology, each node from 0 to N-1 transmits its DATA frames to a sink node N as shown in Figure 1.…”

“…The timeout-MAC (T-MAC) [9], the routing enhanced MAC (R-MAC) [10], the variable load adaptive MAC (VLA-MAC) [11], and the demand wakeup-MAC (DW-MAC) [12] protocols have been proposed to improve energy efficiency through the use of an adaptive duty cycle. In T-MAC, the sensor nodes in the listen mode go to sleep when no activity occurs for a given time interval, called TA.…”

In many sensor network applications, energy efficiency and latency are major design criteria because battery-operated sensor nodes limit network lifetime. In this paper, we propose a new contention-based duty-cycle MAC protocol using a synchronized approach for use in wireless sensor networks. In the proposed MFT-MAC protocol, we use a control frame that considers the number of DATA frames to be transmitted to the next node in order to improve the energy efficiency and reduce the end-to-end delay. During the SLEEP period, each node transmits multiple DATA frames to the next node through the use of the control frame. The performance of the proposed MAC protocol is confirmed through the use of NS-2 simulator.

“…There are several improvements of RMAC that have been introduced such as [21, 22], which can convey more data or more hops in a cycle but still share the basic forwarding mechanism as in RMAC. Demand wake-up MAC (DW-MAC) [9] is an advanced development of RMAC. DW-MAC with a demand wake-up manner can support dynamic traffic loads; hence DW-MAC outperforms RMAC under high traffic loads, but DW-MAC consumes same overhead and achieves higher latency under low traffic loads.…”

“…There are a huge number of power-saving MAC protocols that have been published. The protocols aim to achieve low duty cycle [7–9] or adaptive duty cycle in order to have good performance under different types of traffic [10, 11]. However, when the WSN applications require a long lifetime (months or years), the capacity of battery is still not sufficient.…”

Energy harvesting technology potentially solves the problem of energy efficiency, which is the biggest challenge in wireless sensor networks. The sensor node, which has a capability of harvesting energy from the surrounding environment, is able to achieve infinitive lifetime. The technology promisingly changes the fundamental principle of communication protocols in wireless sensor networks. Instead of saving energy as much as possible, the protocols should guarantee that the harvested energy is equal to or bigger than the consumed energy. At the same time, the protocols are designed to have the efficient operation and maximum network performance. In this paper, we propose ERI-MAC, a new receiver-initiated MAC protocol for energy harvesting sensor networks. ERI-MAC leverages the benefit of receiver-initiated and packet concatenation to achieve good performance both in latency and in energy efficiency. Moreover, ERI-MAC employs a queueing mechanism to adjust the operation of a sensor node following the energy harvesting rate from the surrounding environment. We have extensively evaluated ERI-MAC in a large scale network with a realistic traffic model using the network simulator ns-2. The simulation results show that ERI-MAC achieves good network performance, as well as enabling infinitive lifetime of sensor networks.

“…To eliminate energy waste caused by a continuous renewal of node timeout values in T-MAC, the concept of advertising for data contention is introduced in advertisement-based MAC (ADV-MAC) [7], advertisement-based time-division multiple access (ATMA) [8], and adaptive MAC (AdAMAC) [9]. Several protocols have also been proposed to minimize packet latency, such as demand wakeup MAC (DW-MAC) [10] and multi-divided deliver MAC (MDD-MAC) [11]. DW-MAC introduces a low overhead scheduling algorithm that allows nodes to wake up on demand during the sleep period.…”

Abstract:Wireless sensor networks (WSNs) have been extensively applied in many domains such as smart homes and Internet of Things (IoT). As part of WSNs' communication protocols, back-off mechanisms play an essential role in the deployment of wireless channels for network nodes and have been at the core of ensuring effective communication. The performance of many back-off algorithms is excellent in light or middle load networks. However, it degrades dramatically in heavy load networks. In this paper, we propose an adaptive contention window medium access control (MAC) protocol to improve the throughput performance under heavy load. By using the number of historical collisions as the parameter in the back-off mechanism to reflect the channel status, the size of the contention window is adjusted automatically, and the throughput of network is then improved. Simulation results show that our optimized MAC protocol has higher throughput and energy efficiency.
