“…For example, Figure 2a illustrates a network with TDMA time slots and channels selected by the above routing and scheduling process for each node. This example is cited from [27]. In this network scenario, a sensor node first selects its parent node, and then schedules its transmission in the time slot that is earlier than the slot of the selected parent.…”

“…Then, it switches to other channels according to the sequence of the slots assigned to child nodes. The time consumed for switching from one channel to another is negligible [27]. For instance, in Figure 2, node n11 receives data from the child nodes using channel 1 and 2.…”

“…In the network topology considered in this paper, we assume that all the nodes wake up together at a pre-scheduled sensing period, while they stay in a long sleep period in order to save energy. In [27], the authors proposed a multi-channel TDMA scheduling where each sensor node has a single radio and selects one channel from a set of RF channels. We also consider a similar TDMA scheduling method in this paper.…”

“…In this application, every sensor node periodically wakes up at the same time and sends its sensing data towards the sink node via pre-calculated multi-hop routing paths. We consider a contention-free TDMA protocol, where each node transmits at its time slot, which is pre-allocated during the scheduling process after the routing process is done [27]. The essence of this network structure can be explained in a way that each parent node receives all its child nodes' data and aggregates them into one data packet along with its own sensing data.…”

Conventional IoT applications rely on seamless data collection from the distributed sensor nodes of Wireless Sensor Networks (WSNs). The energy supplied to the sensor node is limited and it depletes after each cycle of data collection. Therefore, data flow from the network to the base station may cease at any time due to the nodes with a dead battery. A replacement of the battery in WSNs is often challenging and requires additional efforts. To ensure the robust operation of WSNs, many fault recovery routing mechanisms have been proposed. Most of the previous fault recovery routing methods incur considerable delays in recovery and high overhead in either energy consumption or device cost. We propose an energy-efficient fail recovery routing method that is aimed to operate over a data aggregation network topology using a TDMA media access control (MAC). This paper introduces a novel fault recovery routing algorithm for TDMA-based WSNs. It finds an optimal neighbor backup parent (NBP) for each node in a way that reduces the energy consumption. The proposed method allows the NBPs to utilize the time slot of the faulty parent nodes, so it eliminates the overhead of TDMA rescheduling for NBPs. To evaluate the fault recovery performance and energy efficiency of the proposed method, we implemented it in C++ simulation program. Simulation experiments with an extensive set of network examples demonstrate that the proposed method can extend the network lifetime by 21% and reduce the energy consumption by 23% compared with the reference methods.Electronics 2018, 7, 444 2 of 21 collisions, which incur retransmissions of packets causing extra energy loss. A time division multiple access (TDMA) protocol is regarded as an effective alternative to CSMA, since it can ensure fair and collision-free data forwarding from all nodes, therefore reducing the energy loss [4,5]. Our proposed method is thus based on TDMA. Regardless of the choice of protocol, however, any WSN is susceptible to devise failure or battery depletion, and therefore it may lose network connectivity.Recent studies on WSNs have achieved considerable enhancement in network architecture and data forwarding protocols to reduce the energy consumption [2]. The primary goal of many WSNs is to maximize the network lifetime even under the event of node failures [6]. Hence, it needs a fail recovery method that operates the rest of the WSN to maintain the desired lifetime.For low-power WSNs, a tree structure topology is often adopted [7], since it permits simple routing paths from all the nodes towards the sink (root) node, which acts as a gateway collecting all the sensing data. In WSNs of tree structure topology, each child node at a lower level forwards its sensing data to its parent node at a higher level until all data are delivered to the sink node [7]. If any parent node fails, then, all nodes in the subtree under the failed parent lose their routing path towards the sink node. A large portion of the network, therefore, can be isolated, resulting in all their sensing ...

Sleep scheduling, also known as duty cycling, which turns sensor nodes on and off in the necessary time, is a common train of thought to save energy. Sleep scheduling has become a significant mechanism to prolong the lifetime of WSNs and many related methods have been proposed in recent years, which have diverse emphases and application areas. This paper classifies those methods in different taxonomies and provides a deep insight into them.
