Summary: Neighbor discovery is crucial in wireless sensor networks for initializing topology and maintaining connectivity. Efforts have been made to reduce latency through recommending potential neighbors, but without careful design it may lead to energy waste. xBOND presents a novel approach with features to evaluate physical proximity and utilizes machine learning to make precise neighbor recommendations. Simulation experiments show significant efficiency gains over existing methods.

Summary: This article proposes a novel distributed optimization framework for data collection in duty-cycle wireless sensor networks (WSNs) with energy harvesting. The framework utilizes a mobile collector called SenCar to collect data from selected sensors called anchors, overcoming the bottlenecks caused by energy distribution variations. The problem is divided into two steps: calculating the optimal number of anchors and determining them using an adaptive anchor selection algorithm. Furthermore, a distributed algorithm with uncoordinated step size is proposed to improve convergence rate, and the explicit convergence analysis is provided.

Summary: In this paper, a novel accumulative Interest-based content-store architecture called E-DRAFT is proposed for NDN-based WMSNs to improve the efficiency of individual nodes as well as the overall network, and to control packet flooding. The ndnSIM simulator is used for comprehensive simulations, and the results show that the proposed approach effectively stops additional packet flooding and enhances processing efficiency in storing and retrieving Data packets compared to existing methodologies.

Summary: This paper aims to experimentally implement a hybrid energy management solution combining DVFS and duty-cycling to improve energy efficiency of IoT services. Hardware optimization is performed by selecting the low-power microcontroller MSP430. The energy-saving design is evaluated by defining normalized power. Extensive simulations and real-world implementations show that energy consumption can be significantly reduced in high-data IoT use cases.

Summary: Many OR schemes neglect the diversity of network nodes and the impact of multiple network attributes on routing decisions. This paper proposes a novel protocol, FLORA, which addresses these issues by defining routing zones, prioritizing nodes, and selecting a final relay node. Experimental simulations demonstrate that FLORA outperforms its counterparts in terms of various performance metrics.

Summary: The duty cycling process is a promising approach for designing routing protocols in resource-constrained Wireless Sensor Networks (WSNs). It improves network lifetime and transmission efficiency compared to conventional protocols. This study proposes a routing protocol that divides the duty cycle into slots to minimize idle listening and uses the opportunistic concept to minimize sender waiting. The simulation analysis shows that the proposed scheme outperforms existing ones in terms of transmission delay, energy consumption, and network throughput.

Summary: In this paper, a fuzzy based adaptive duty cycling algorithm is proposed to achieve network sustainability in harvesting sensor actor networks. The algorithm considers current residual energy, predicted harvesting energy, and predicted residual energy parameters as fuzzy input variables to estimate duty cycle for a sensor node. Simulation results demonstrate the efficacy of the proposed mechanism in achieving network sustainability.
