“…A real-time monitoring system enables to process sensor data during service operation (Lee et al 2010). Looking at technologies for data analyses, effective fault diagnosis in wireless sensor networks is important for a successful service operation (Hamdan et al 2012). Abstraction of functionalities for heterogeneous devices is required in order to support interoperability for concurrency management and failure detection in whole systems (Baldoni et al 2010).…”

Smart services serve customers and their individual, continuously changing needs; information and communications technology enables such services. The interactions between customers and service providers form the basis for co-created value. A growing interest in smart services has been reported in the literature in recent years. However, a categorization of the literature and relevant research fields is still missing. This article presents a structured literature search in which 109 relevant publications were identified. The publications are clustered in 13 topics and across five phases of the lifecycle of a smart service. The status quo is analyzed, and a heat map is created that graphically shows the research intensity in various dimensions. The results show that there is diverse knowledge related to the various topics associated with smart services. One finding suggests that economic aspects such as new business models or pricing strategies are rarely considered in the literature. Additionally, the customer plays a minor role in IS publications. Machine learning and knowledge management are identified as promising fields that should be the focus of further research and practical applications. Concrete ideas for future research are presented and discussed and will contribute to academic knowledge. Addressing the identified research gaps can help practitioners successfully provide smart services.

“…Some attempts use the second antenna to detect and abort collisions during the transmission immediately. This approach is known as Carrier Sense Multiple Access with Collision Notification (CSMA/CN) and obtains part of CSMA/CD's benefits in wireless environments [25]. But the major problem is still the cost for the second antenna.…”

A Wireless Sensor Network (WSN) is a network of many nodes. These nodes are equipped with sensors which communicate wirelessly using techniques for radio frequency transmission. This network helps to measure and record the physical environment variables and to forward these results to a central location known as a sink. As WSN nodes are only supplied by a battery, the primary challenge is to reduce the energy consumption. The MAC layer is responsible for the establishment of a reliable and efficient communication link between WSN nodes and is responsible for energy waste. The newly proposed MAC protocol in this paper uses an improved variant of CSMA which implements weak signal detection (WSD). This technique enables dividing collisions from weak signals and takes appropriate decisions to reduce energy consumption. The CSMA/WSD protocol is presented as a flowchart and implemented in OMNeT++ by using the MiXiM framework structure. Implementation tests are performed to prove the validity of the implemented protocol in different scenarios. Different simulation scenarios show that this protocol offers a higher throughput, a smaller mean backoff time, and less average delay in critical environments.

Context awareness is one of the major research areas of pervasive computing. Several proposals for the design of context aware applications rely on a closed feedback loop that performs four phases. Monitoring and collecting context (phase 1), analyzing the collected context to detect changes (phase 2), deciding adaptation actions related to the changes (phase 3) and performing and executing the corresponding adaptation actions (phase 4) to deal with the changes. In this paper, we discuss the analysis phase (phase 2). We propose an analysis approach that aims at detecting the context changes and raising notifications when changes occur. The analysis approach is formalized through an analysis process that aims to facilitate the design of the analysis phase for a context aware application. The analysis process is described by a graph illustrating a set of steps that must be executed to perform the analysis process. In order to demonstrate the usability of our approach, we present a Smart Building case study.978-1-4799-8676-7/15/$31.
