One of the main design challenges in wireless sensor networks (WSNs) is achieving a high-data-rate transmission for individual sensor devices. The high altitude platform (HAP) is an important communication relay platform for WSNs and next-generation wireless networks. Multiple-input multiple-output (MIMO) techniques provide the diversity and multiplexing(More)
A typical application scenario of remote wireless sensor networks (WSNs) is identified as an emergency scenario. One of the greatest design challenges for communications in emergency scenarios is energy-efficient transmission, due to scarce electrical energy in large-scale natural and man-made disasters. Integrated high altitude platform (HAP)/satellite(More)
In this paper, the quality of service (QoS) metrics and user demand model are established in high altitude platforms (HAPs) broadband communication network. A methodology of mobile base station placement is proposed with QoS and user demand guarantee for the first time. Besides, the HAPs placement optimization framework is established by optimizing the(More)
This article investigates the capacity problem of an integrated remote wireless sensor and satellite network (IWSSN) in emergency scenarios. We formulate a general model to evaluate the remote sensor and satellite network capacity. Compared to most existing works for ground networks, the proposed model is time varying and space oriented. To capture the(More)
The high altitude platform (HAP) is an important communication platform for cloud storage in the next generation internet. The Multiple-input multiple-output (MIMO) techniques provide the significant diversity and multiplexing gain, which can improve the network performance effectively. In this paper, a virtual MIMO model is proposed by networking the(More)
The usable satellite spectrum is becoming scarce due to static spectrum allocation policies. Cognitive radio approaches have already demonstrated their potential towards spectral efficiency for providing more spectrum access opportunities to secondary user (SU) with sufficient protection to licensed primary user (PU). Hence, recent scientific literature has(More)
