“…Their scheme aims to maximize the UE average capacity by using a non-homogeneous discrete time Markov chain to model the evolution of the UE state. M. Gerasimenko et al [38] and A. Shafie et al [39] considered Markov chains for developing connectivity strategies in the mmWave and THz network respectively, where they assumed that the UE maintains backup connections with the other nonblocked access points. However, in practical systems, a UE can maintain connections with only a limited number of access points.…”

Wireless communication over terahertz (THz) frequency bands is envisioned as the key enabler of many applications and services offered in 6G networks. The abundantly available bandwidth in THz frequencies can satisfy the ultra-high user throughput requirements and accommodate a massive number of connected devices. However, poor propagation characteristics, shadowing, and blockages may result in sudden outages and necessitate frequent handovers. Therefore, an inefficient handover procedure will impose severe challenges in meeting the ultra-high reliability and low latency requirements of emerging applications. In blockage driven mmWave and THz networks, a higher multiconnectivity degree and efficient handover procedures are needed to reduce the data plane interruptions and to achieve high reliability. We present an analytical model to study the impact of handover procedures and multi-connectivity degree on the latency and reliability of blockage driven wireless networks. From the network protocol design perspective, our study offers a quick and accurate way to envisage how network architecture and protocols should evolve in terms of multi-connectivity degrees and handover procedural efficiency. Our results suggest that, for THz systems, coverage range should be increased even if it comes at the cost of increased initial access and base station discovery times.

In order to ensure the strong real-time information sharing of Aerial Ad hoc Network, a low-delay information sharing algorithm for multiple-radio-per-platform networking is proposed based on the directional transmission capability of phased-array antenna. The algorithm introduces virtual nodes and virtual links in the process of topology generation first. By extracting topology information and choosing link grouping, it can effectively reduce redundant transmission and transmission latency of information sharing. Then, it is verified through simulation that the algorithm can reduce the latency by up to 49.8% and eliminate transmission redundancy. In addition, a direction selection algorithm is proposed for the variation of antenna beam direction. Simulation results show that the algorithm can further reduce the latency of information sharing and ensure the real time of information sharing, thus further improving the network performance.

“…Measurements and analysis have shown a dramatic performance gain when spatial diversity is used to enhance coverage in mm-wave communications [39,40,41]. By combining a proper coverage plan [42] and mechanisms for providing connections from multiple APs/cells, e.g., MC and relaying techniques, we can significantly improve throughput, reliability, and robustness in mm-wave communications [43,44].…”

“…Multiple connections can be established either by using several resources of the same node (intra-site), e.g., different frequency bands, or with multiple cells/APs (inter-site). The latter exploits spatial macro-diversity to provide independent links [50,39,40,43]. We can also distinguish between inter-frequency and intra-frequency MC, depending on whether the multiple connections use the same frequency band or not.…”
