“…Cellular Network Architecture System using High Altitude Platforms High Altitude Platforms (HAPs) are airships or planes operating at the stratosphere at 17 -22 km altitude. These platforms have the ability to deliver information quickly and can serve a number of users using fewer communications infrastructures than which are required by terrestrial transmission system (Grace et al, 2002).…”

A B S T R A C TKeywords: 5G HAP MTC WSN energy consumption Technology development and socio-economic transformation have increased the demand for 5G cellular networks. They are expected to send information quickly and support many use cases emerging from a variety of applications. One of the use cases on the 5G network is the massive MTC (Machine Type Communication), wherein wireless sensor network (WSN) is a typical application. Challenges faced by a 5G cellular network are how to model an architecture/topology to support WSN and to solve energy consumption efficiency problem in WSN. So, to overcome these challenges, a HAP system integrated with WSN which uses Low Energy Adaptive Hierarchy routing protocol is implemented. The HAP system is designed to be used at a 20-km altitude, and the topologies used are those with and without clustering. It uses 1,000 sensor nodes and Low Energy Adaptive Clustering Hierarchy protocol. This system was simulated using MATLAB. Simulations were performed to analyze the energy consumption, the number of dead nodes, and the average total packets which were sent to HAP for non-clustered topology and clustered topology. Simulation results showed that the clustered topology could reduce energy consumption and the number of dead nodes while increasing the total packet sent to HAP.

“…The purpose of studying call admission control strategy is to ensure the lower new call blocking probability and handover dropping probability without degrading the performance of the system. Since the cellular coverage area can improve the system performance and increase the flexibility of the system [1], Li use location information of HAPS and users to make the overlapping area to ensure the handover strategy, which helps determine and block new calls that may cause a handover failure, resulting in a near-zero handover dropping rate [2]. These methods can adapt to dynamic change of platform position, but cannot deal with the situation of attitude change.…”

Abstract. The large changing of link capacity and number of users caused by the movement of both platform and users in communication system based on high altitude platform station (HAPS) will resulting in high dropping rate of handover and reduce resource utilization. In order to solve these problems, this paper proposes an adaptive call admission control strategy based on reinforcement learning approach. The goal of this strategy is to maximize long-term gains of system, with the introduction of cross-layer interaction and the service downgraded. In order to access different traffics adaptively, the access utility of handover traffics and new call traffics is designed in different state of communication system. Numerical simulation result shows that the proposed call admission control strategy can enhance bandwidth resource utilization and the performances of handover traffics.

“…HAPs will have relatively loose station-keeping characteristics compared with satellites, and the effects of platform drift on a cellular structure and the resulting inter-cell handover requirements have been investigated . Cellular resource management strategies have also been developed for HAP use (Grace et al, 2002). Configurations of multiple HAPs can also reuse the spectrum.…”
