In the domain of distributed embedded systems, available resources regarding computing power, energy, and memory are strongly limited. With focus on the energy resources, communication hardware and communication tasks represent critical consumers for most of the common application scenarios. Accordingly, optimised approaches for the communication have to be found, including routing, topology control, and scheduling. Wake-Up-Receivers (WuRx) represent a promising approach for minimising the energy consumption in wireless communication environments. To use the conceptual benefits of such technology, an adapted communication behaviour is required. Communication paradigm, communication protocols as well as the runtime behaviour must fit together.In this paper, we introduce a WuRx-optimised routing and topology optimisation approach -WRTA. We discuss the hardware integration as well as the adaptation of the communication task scheduling on application layer. The design matching process of all these aspects allows significant improvements of the energyefficiency in typical sensor network scenarios. For achieving these goals, WRTA represents a lightweight protocol for data-centric WSN environments. The approach combines complex route path calculations and topology optimisation mechanisms, considering a given asynchronous communi cation environment.For proof of concept, we implement several heterogeneous test benches in both soft-and hardware. Hence, the presented simulation results as well as the respective real world measurements provide interesting results regarding the scalability and the efficiency. The analysis of the data shows minimum protocol overhead and outstanding characteristics regarding scalability and robustness. We clarify that application-specific adaptations & configurations within the overall system architecture are essential to ensure an reliable communication behaviour in energy selfsufficient WuRx environments.

A promising idea for optimising the power consumption of mobile communication devices represents the usage of an additional ultra-low-power receiver unit, which is able to control the main transceiver in order to reduce the standby power consumption of the overall system. Such a Wake-Up-Receiver (WuRx) unit senses the medium and switches on the communication interfaces in case of an external request. Otherwise, all system components for the network communication are completely switched off. Especially in the domain of resource-limited and embedded devices, WuRx technologies enable novel communication paradigms.

But on the application layer, not all scenarios allow the efficient usage of such WuRx technologies. Dependent on environmental parameters, technological limitations and conceptual requirements, different strategies are necessary to ensure energy-efficient system operation.

In this article, we present a critical analysis of the capabilities and the conceptual limitations of WuRx approaches. Therefore, we identify critical parameters for WuRx concepts, which limit the efficiency in real world scenarios. Our goal is to classify sufficient fields of application. Furthermore we evaluate the influences of these parameters on the system behaviour. In addition, we introduce heterogeneous energy harvesting approaches as an efficient way for the system optimisation. The proposed technologies are capable to be integrated into small-sized wireless sensor platforms and prolong the system uptime significantly.

The presented simulation results are focusing on actual smart metering scenarios and wireless sensor networks. Based on these measurements, we were able to apply further optimisation steps within the system configuration on the application layer. In this context, we focus on application-specific key issues, like the trade-off between measurement quality and quantity, the usage of data buffering approaches and QoS capabilities.

“…These protocols are responsible for robust communication links and stable multi-hop route path. One the other side, if we are talking about wireless network optimisation, we also have to look for efficient ways to manage data on the application layer [8]. Approaches have to be found, which reduce the amount of communication data in order to reduce the respective power consumption for the transmission tasks [9].…”

WSN and SANET topologies generate huge amount of heterogeneous data, which has to be transmitted in a dynam ically changing network infrastructure. Especially in the domain of wireless low-power applications, the energy-efficiency and the prioritisation of communication tasks is critical. Several research areas deal with this issue. They optimising the respective hardware components as well as the protocols within the PHY, MAC or network layer. But for an optimised media transport in the topology also the data management and the task scheduling on the application layer is essential. Here, the key challenge is to minimise the data amount without decreasing the information quality. Related research work in the field of data aggregation and data fusion ofTers interesting techniques for an efficient data handling.In this paper, we discuss usual ways for data aggregation, in cluding the adapted communication process. We critically analyse the benefits in theory and compare these conceptual advantages with measured real-world results. The evaluation was done in two steps. The first one is based on simulation scenarios of typical WSN/SANET applications. In a second step, we implement a demonstrator platform for a respective real-world environment.The test bed configuration is similar to the simulation scenario and provides comparable data. Based on the results and the respective analysis, we propose feasible methods for optimising data aggregation techniques. We clarify, that these improvements are essential for an efficient usage in resource-limited, embedded sensor network environments.
