The development of IPv6-based network architectures for Internet of Things (IoT) systems is a feasible approach to widen the horizon for more effective applications, but remains a challenge. Network routing needs to be effectively addressed in such environments of scarce computational and energy resources. The Internet Engineering Task Force (IETF) specified the IPv6 Routing Protocol for Low Power and Lossy Network (RPL) to provide a basic IPv6-based routing framework for IoT networks. However, the RPL design has the potential of extending its functionality to a further limit and incorporating the support of advanced routing mechanisms. These include multipath routing which has opened the doors for great improvements towards efficient energy balancing, load distribution, and even more. This paper fulfilled a need for an effective review of recent advancements in Internet of Things (IoT) networking. In particular, it presented an effective review and provided a taxonomy of the different multipath routing solutions enhancing the RPL protocol. The aim was to discover its current state and outline the importance of integrating such a mechanism into RPL to revive its potentiality to a wider range of IoT applications. This paper also discussed the latest research findings and provided some insights into plausible follow-up researches.

Transmission Capability

A large amount of image and video streaming need to be transmitted in wireless multimedia sensor networks (WMSNs), and a single path can not meet the requirement of image and video streaming transmission. Multipath routing protocol can increase transmission capability and be appropriate for WMSNs. TPGF is the first multipath routing protocol which is suitable for WMSNs. After TPGF is analyzed deeply, we propose an Energy Balancing Multipath Routing protocol (EBMR) which considers nodes' residual energy and the distance between the node and the sink. Compared to TPGF, EBMPR can more evenly consume nodes' energy and prolong the network lifetime. Simulation results show the advantage of EBMR.

Internet of Things (IoT) opens the way for many of the research areas out of which Network lifetime extension is one of the craziest research areas. Proposing a design for any sensor network routing protocol needs to concentrate on extending the network's existence. Minimizing energy consumption leads to an extension of the life of the network. Routing Protocol for Low power and Lossy Networks (RPL) is the routing protocol designed by IETF especially which meets the necessities of the constrained environments in IoT. This research article attempts improve performance of the RPL protocol by incorporating the soft-computing techniques. Here, a fuzzy logic-based approach is used which considers DIO_MIN as the essential factor/metric to improve the performance of RPL (i.e., reducing the energy consumption). The COOJA simulator is used for performing the simulations and assessment purpose. Results obtained from this research prove that fuzzy logic can be exercised to improving routing protocol quality (i.e., RPL) in terms of energy consumption.

In the wireless sensor network routing protocol design, the sensor node monitoring data in multi-hop relay approach to sink node for transmission. For sink aggregation node fixed network, the nearby sink nodes of sensor nodes need to transfer other nodes of the monitoring data, consequently, it consumes large amounts of energy, and it's easy to premature death, making the network connectivity decline, even making the network intersected, shorten the lifetime of the network. In order to solve this problem, from the view of sink node, this thesis brings forward a protocol of SERP, which is a energy balancing routing protocol based on sink Mobility and prolongs the lifetime of network. It adopts the strategy of sink movement which makes the hot nodes inside the network take turns, balances the load among them. In SERP, firstly, the WSN deployment area is divided into finite Virtual cells ;Secondly ,we make the center of each virtual cell as the mobile position of sink node; at last, we confirm the residence time when sink node stays in each position through linear programming. Finally, the paper makes simulation al analysis aiming at above-mentioned routing protocols . The result shows that the inside node energy consumption is comparatively balanced and efficient, and the network lifetime is prolonged effectively.

The development and application of the Internet of things and the basic structure of wireless sensor network are briefly introduced,routing protocol in wireless sensor network is studied in detail. Since the wireless sensor network is a kind of energy-limited and resource-limited network, the routing protocol must guarantee the smaller routing expenses and the reducing energy consumption. Based on the analysis and research of existing wireless sensor network routing protocol, this paper emphasizes on the detailed analysis of the hierarchy routing protocol LEACH algorithm.The paper also introduces two improved algorithms according to the limit of LEACH protocol.

Abstract The wireless sensor networks (WSNs) are special network which has purpose of gathering information in certain area. Multipath routing is the paramount path of addressing QoS and energy balancing concerns in low power and lossy networks (LLNs) especially in IoT technology. Most of the extant efforts bring the limited number of disjoint paths into play, and intersect the traffic among them pursuant to a compound metric or centralized optimization problem. This paper proposes a multi-class multipath routing protocol for LLNs (called M2RPL), that construct a braided multipath routing graph based on the standard RPL (IPv6 Routing Protocol for Low-Power and Lossy Networks) protocol, and an energy balanced optimal rate assignment mechanism (EBORA) that solves a local multi class optimization problem for minimum cost traffic rate assignment. Moreover the algorithm tries to maximize network lifetime by equalizing the energy dissipation rates of equi-level nodes. The simulation results expose the efficiency of the proposed framework, leading to an average 15% increase in lifetime, and improved QoS performance in terms of delay and reliability, compared to some well-known algorithms.

Ebp Implementation

Purpose The current investigation is a follow-up from a previous study examining child language diagnostic decision making in school-based speech-language pathologists (SLPs). The purpose of this study was to examine the SLPs' perspectives regarding the use of evidence-based practice (EBP) in their clinical work. Method Semistructured phone interviews were conducted with 25 school-based SLPs who previously participated in an earlier study by Fulcher-Rood et al. 2018). SLPs were asked questions regarding their definition of EBP, the value of research evidence, contexts in which they implement scientific literature in clinical practice, and the barriers to implementing EBP. Results SLPs' definitions of EBP differed from current definitions, in that SLPs only included the use of research findings. SLPs seem to discuss EBP as it relates to treatment and not assessment. Reported barriers to EBP implementation were insufficient time, limited funding, and restrictions from their employment setting. SLPs found it difficult to translate research findings to clinical practice. SLPs implemented external research evidence when they did not have enough clinical expertise regarding a specific client or when they needed scientific evidence to support a strategy they used. Conclusions SLPs appear to use EBP for specific reasons and not for every clinical decision they make. In addition, SLPs rely on EBP for treatment decisions and not for assessment decisions. Educational systems potentially present other challenges that need to be considered for EBP implementation. Considerations for implementation science and the research-to-practice gap are discussed.
