“…Some works of the real-time scheduling problem of IWSANs (e.g., [28]- [31]) do not address aperiodic and unpredictable data flows. Additionally, although the works [32] and [33] consider how to schedule aperiodic and unpredictable data flows, too much interference is introduced into other flows.…”

“…The second type of data flow consists of aperiodic and unpredictable data flows, such as alarms and artificial triggering events. We assume that any two aperiodic data flows do not interfere with each other because this type of data flow is infrequent in real systems [32]. These data flows must be delivered to their destinations before their deadlines.…”

Abstract-A smart factory generates vast amounts of data that require transmission via large-scale wireless networks. Thus, the reliability and real-time performance of large-scale wireless networks are essential for industrial production. A distributed data transmission scheme is suitable for large-scale networks, but is incapable of optimizing performance. By contrast, a centralized scheme relies on knowledge of global information and is hindered by scalability issues. To overcome these limitations, a hybrid scheme is needed. We propose a hierarchical data transmission framework that integrates the advantages of these schemes and makes a tradeoff among real-time performance, reliability, and scalability. The top level performs coarse-grained management to improve scalability and reliability by coordinating communication resources among subnetworks. The bottom level performs fine-grained management in each subnetwork, for which we propose an intrasubnetwork centralized scheduling algorithm to schedule periodic and aperiodic flows. We conduct both extensive simulations and realistic testbed experiments. The results indicate that our method has better schedulability and reduces packet loss by up to 22% relative to existing methods.

“…TSCH is topology independent and suitable for multihop networks [7] because the frequency hopping nature makes efficient use of the available resources. Fig.1 shows the network with different transmissions and receptions between the motes and the transmissions are scheduled using two cycles each containing 3 sloframes satisfying the TSCH features such as time slotted access i.e D→C and A→C used different time slots and the channel hopping nature i.e B→A and G→D transmissions and the multi channel communication mechanism i.e F→D and E→C transmitting in the same time slot using different channel offsets.…”

Abstract-Time-Slotted Channel hopping (TSCH) that was introduced in IEEE802.15.4e is a promising technique to offer deterministic data deliveries in Wireless Sensor Networks (WSN). Its main strength lies in using multiple channels for the transmissions, using frequency hopping method. However, it takes more time for initializing the network, as beacons have to be released on multiple frequencies and scanning needs to be carried out by the devices in all those frequencies for joining the network. In this work, a simulation study is carried out to investigate the effect of these delays for different types of multihop networks. The benefit of introducing multiple coordinators in reducing these time delays is also studied. It is found that the delays are increasing linearly with the number of hops in the network and adding an additional coordinator can bring down the initialization time by half.

This paper presents a solution for priority-based data transmission in heterogeneous wireless sensor networks. Considering the requirements of each event separately while delivering a data simultaneously is a challenging task in the sensor networks. Therefore, we present the PriTLP protocol for prioritizing the information at various data processing units in the multi-hop topology network. It brings a distributed approach for taking decisions on behalf of the sink node which fastens the data processing, reduces the communication delays, and prolongs the network life. It performs two operations, namely data prioritization and scheduling; and identifying the congestion degree of the network. The reported work is implemented and validated over the RF TestBed by managing the buffer level. It shows high packet delivery ratio, greater throughput, and fewer communication delays of high priority-based traffic flow over regular flows.
