In this paper, we investigate the performance of using high altitude platforms (HAPs) for low power wireless sensor network (WSN) applications. In our study, HAPs are employed to replace the sink usually deployed on the ground and collect data from sensor nodes. Two scenarios of employing the HAP as the sink in the WSN are established. Multiple sensor nodes are organized in an ad-hoc manner or in...
In this paper, we investigate a cost-effective wireless broadband service provision from high altitude platforms (HAPs) and an economical business model design. Different deployment strategies of HAP system are illustrated in terms of a stand-alone HAP system and in collaboration with terrestrial or satellite systems. An IEEE 802.16 fixed broadband service from HAP is examined to show the effectiveness...
In this paper, we will discuss the business model design for the deployment of capacity-driven services from high altitude platforms (HAPs). Key factors of successfully delivering the HAP services will be investigated in terms of coexisting with current major wireless broadband and cellular network operators in a long term perspective. A partnership-based business model will be proposed and demonstrated...
In this paper, performance of providing WiMAX from high altitude platforms (HAPs) with multiple antenna payload will be investigated as well as considering the coexistence capability with multiple-operator terrestrial deployments. A scenario of a HAP and terrestrial WiMAX base stations deployed inside a HAP coverage area with a radius at 30 km will be proposed. HAP cellular formation with different...
The evaluation of uplink performance of delivering WiMAX services from high altitude platforms (HAPs) is presented. System performance is assessed in terms of coexisting capability with terrestrial WiMAX system, employing directive antenna models and optimization techniques. Simulation results show that providing WiMAX via HAPs can effectively achieve 29 dB at the edge of the HAP coverage area with...
