With the rapid advancement of wireless network technologies and the constant increase in the number of mobile devices, enormous amount of data is generated from a set of user equipments (UEs), such as mobile phones and wearable devices. How to power these devices wirelessly becomes a challenging issue. Meanwhile, data and energy integrated communication networks (DEINs) are emerging as a new type...
This paper describes a new type of communication network called data and energy integrated communication networks (DEINs), which integrates the traditionally separate two processes, i.e., wireless information transfer (WIT) and wireless energy transfer (WET), fulfilling co-transmission of data and energy. In particular, the energy transmission using radio frequency is for the purpose of energy harvesting...
With the growing deployment of wireless communication technologies, radio spectrum is becoming a scarce resource. Thus, mechanisms to efficiently allocate the available spectrum are of interest. In this paper, we model the radio spectrum allocation problem as a sealed-bid reserve auction, and propose SMALL, which is a Strategy-proof Mechanism for radio spectrum ALLocation. Furthermore, we extend SMALL...
The mixture of users with different bandwidth capability presents new challenges to optimize the transmission performance of the next generation wireless networks. This paper focuses on resource allocation for pervasive wireless networks with component carrier (CC) aggregation. Distinguished from many existing methods that decompose the resource optimization problem into two sequence steps, i.e.,...
In this paper, we concentrated on resource allocation for heterogeneous traffic in OFDM wireless networks. We considered three types of traffic, i.e. hard QoS, soft QoS and best effort (BE), the characteristics of which can be described by three different utility functions. We proposed a utility-based cross-layer resource scheduling model, which performs combinational-optimization adaptive resources...
