We present an explicit adaptive traffic allocation scheme for optimum distribution in heterogeneous networks, where data traffic is broken down into multiple sub-flows, such that the aggregate of these multiple sub-flows at the terminal are merged into the original flow. For simplicity, parallel data transmission through inter-network cooperation is modeled as a sequent M/M/1 queue system. We aim...
The content dissemination among mobile users can be solved by self-facilitated mobile ad hoc networks (MANET) in an infrastructure environment. But the devices used to make up the mobile ad hoc networks usually have a limited radio transmission range, sporadic node density and power limitation, which makes MANET become intermittently connected. In this paper we focus on the content delivery problem...
In this paper, heterogeneous services in multiuser multiple-input multiple-output (MIMO)-Relay systems are investigated, where the relays work in amplify-and-forward mode. A utility based adaptive scheduling algorithm is proposed, which aims to maximize user satisfaction as well as system spectral efficiency. Joint optimal carriers and spatial subchannels allocation is considered based on the proposed...
An explicit adaptive traffic allocation scheme is investigated in terms of the cooperation across wireless wide area networks (WWANs) and wireless personal area network (WPAN). The analysis and numerical simulations indicate that the proposed scheme achieves inter-networking load balance to minimize the whole transmission delay and expands the communication ability of single-mode terminals to support...
Long-term evolution (LTE) of the UMTS terrestrial radio access and radio access network is considered to ensure the competitiveness of 3GPP radio-access technology in a longer time frame. To minimize/optimize the user equipment (UE) power consumption, and further to support various services and large amount of data transmissions, a discontinuous reception (DRX) mechanism with adjustable DRX cycles...
