It is a great challenge to evaluate the network performance of cellular mobile communication
systems. In this paper, we propose new spatial spectrum and energy efficiency models for …

Crowd sensing harnesses the power of the crowd by mobilizing a large number of users
carrying various mobile and networked devices to collect data with the intrinsic multi-modal …

With the increasingly serious problem of the aging population, creating an efficient and real-
time health management and feedback system based on the healthcare Internet of Things …

This paper proposes a centralized decision making framework at the macro base station
(MBS) for device-to-device (D2D) communication underlaying a two-tier cellular network. We …

Ultra-dense networks can further improve the spectrum efficiency (SE) and the energy
efficiency (EE). However, the interference avoidance and the green design are becoming …

To satisfy the recent growth of mobile data usage, small cells are recommended to deploy
into conventional cellular networks. However, the massive backhaul traffic is a troublesome …

Cognitive radio (CR) is considered one of the prominent techniques for improving the
utilization of the radio spectrum. A CR network (ie, secondary network) opportunistically …

In resource constrained wireless systems, achieving higher spectral efficiency (SE) and
energy efficiency (EE), and greater rate fairness are conflicting objectives. Here, a general …

This paper proposes a joint energy efficiency (EE) and spectrum efficiency (SE) tradeoff
analysis as a multi-objective optimization problem (MOP) in the uplink of multi-user multi …

Deploying femtocells underlaying macrocells is a promising way to improve the capacity and
enhance the coverage of cellular systems. However, such a two-tier network also gives rise …
