“…1 the isolation probability versus node density is presented in order to evaluate connectivity enhancement from the usage of selection combining reception scheme. From the results of Fig.1, it is obvious that connectivity diversity gain is almost 30% and it can probably reach higher values with the adoption of a more complex and efficient diversity technique such as maximal-ratio combining (MRC) [14].…”

In this paper, common diversity techniques are proposed in order to achieve connectivity improvement in wireless sensor networks under correlated shadowing channels. In the operational environment of WSN's, shadowing is the dominant fading mechanism and has the greatest impact on network's performance and connectivity. A new model based on Inverse Gaussian and Bivariate Inverse Gaussian distribution is proposed for approximating the statistical behavior of Signal-toNoise ratio (SNR) for both correlated and uncorrelated shadowing channels. In order to counterbalance the impact of fading, we suggest the use of Selection Combining (SC) diversity reception scheme. Moreover, our analysis is based on the realistic assumption that the corresponding radio links of the diversity branches are considered correlated. Finally, the connectivity gain from the use of diversity is formulated and calculated for several operational parameters.

“…One noteworthy endeavor involved obtaining real-world data through the use of a 60 GHz channel sounder to explore the application of the multipleinput multiple-output (MIMO) technique within indoor environments, as documented in [13]. The enhancement in multi-hop indoor wireless connectivity was achieved through the implementation of a diversity reception scheme, as discussed in [14]. Another innovative approach leveraged the physical characteristics of the uniform planar array (U-PA) and 2-dimensional discrete Fourier transform (2D-DFT) to introduce a novel channel estimation scheme tailored for 60 GHz massive MIMO systems, as outlined in [15].…”

The fourth industrial revolution focuses on the digitization and automation of supply chains resulting in a significant transformation of methods for goods production and delivery systems. To enable this, automated warehousing is demanding unprecedented vehicle-to-vehicle and vehicle-to-infrastructure communication rates and reliability. The 60 GHz frequency band can deliver multi-gigabit/second data rates to satisfy the increasing demands of network connectivity by smart warehouses. In this paper, we aim to investigate the network connectivity in the 60 GHz millimeter-wave band inside an automated warehouse. A key hindrance to robust and high-speed network connectivity, especially, at mmWave frequencies stems from numerous non-line-of-sight (nLOS) paths in the transmission medium due to various interacting objects such as metal shelves and storage boxes. The continual change in the warehouse storage configuration significantly affects the multipath reflected components and shadow fading effects, thus adding complexity to establishing stable, yet fast, network coverage. In this study, network connectivity in an automated warehouse is analyzed at 60 GHz using Network Simulator-3 (NS-3) channel simulations. We examine a simple warehouse model with several metallic shelves and storage materials of standard proportions. Our investigation indicates that the indoor warehouse network performance relies on the line-of-sight and nLOS propagation paths, the existence of reflective materials, and the autonomous material handling agents present around the access point (AP). In addition, we discuss the network performance under varied conditions including the AP height and storage materials on the warehouse shelves. We also analyze the network performance in each aisle of the warehouse in addition to its SINR heatmap to understand the 60 GHz network connectivity.

“…These issues must be solved in order to make the VANET more successful. Some of the issues that are needed to be focused are signal fading [10], distortions, connectivity [11], bandwidth limitations, small effective diameter, security and the nature of the routing protocol. Signal fading occurs due to the presence of obstacles such as the buildings, walls between the source and destination.…”

Vehicular Ad-Hoc Network (VANET) [1] which is a sub-type of the mobile ad-hoc networks provides wireless communication between the vehicles and to the Road Side Units (RSU) [2]. In VANET, the communication between the vehicles is used for various purposes like safety, comfort and entertainment.We use the vehicles as the portable nodes to create the mobile network. The VANET uses all the vehicles in the nearby distance as a wireless router or node to form a network. The vehicles can dynamically come in or drop out of the network as they move. The working of the VANET depends on how the routing of data is done in the network. In the recent years, the number of accidents has been increased to a greater count. In order to eradicate this, the implementation of VANET technology is being used in various modes of transportation. Even though VANET has been proposed to be a successful network model, it has some issues to overcome. The most major issues are the connectivity and the signal fading issue. We can overcome some of the issues in VANET by using the Artificial Bee Colony Algorithm (ABC) [3]. The proposed use of the algorithm in VANET may resolve some of the issues effectively.
