Summary: This research focuses on the communication and connectivity issues in random Wireless Sensor Networks (WSNs), particularly emphasizing the impact of the sink node and its placement on network connectivity and sensor connection rate. The results show that relocating the sink node from the network center to the periphery leads to a significant decline in the sensor connection rate. Additionally, partial connectivity and sensor connection rate are more suitable metrics for evaluating the communication capability of random WSNs.

Summary: This study proposes a scheme for improving the lifespan of wireless sensor networks (WSNs) and enhancing network connectivity. The scheme utilizes energy harvesting and wireless power transfer techniques, and is targeted at WSNs with solar-powered sensor nodes. The scheme employs clustering and adjusting data collection rate to alleviate the hotspot problem. Simulation results demonstrate that the scheme reduces the number of blackout nodes in hotspot areas and improves data collection and monitoring performance.

Summary: The 'Centroid-Based Routing (CBR)' protocol aims to optimize the total system energy for a wireless sensor network by using a mobile Sink Node (SN) and Centroid Point (CP). By forming clusters with Cluster Head (CH) nodes and balancing energy distribution, CBR ensures longer lasting sensor nodes compared to other existing models. Simulation results demonstrate the efficiency of CBR in terms of energy utilization and network lifetime for non-uniformly distributed sensor nodes.

Summary: This paper studies the employment of a mobile charger to charge lifetime-critical sensors under the multi-node partial-charging model. The goal is to not only minimize the number of dead sensors but also reduce the dead durations of sensors. A novel approximation algorithm is proposed and experimental results show its effectiveness in reducing both the average and maximum sensor dead durations.
