IEEE International Conference on Communications in China (ICCC)

作者： Mei Wang Hailun Xia Chunyan Feng Beijing Key Laboratory of Network System Architecture and Convergence Beijing University of Posts and Telecommunications Beijing China

To mitigate cross-tier interference, almost blank subframe (ABS) has been exploited for heterogeneous networks (HetNet). Macrocells mute or reduce transmission power to avoid interference to picocell edge users. However, the former results in unfairness between macrocells and picocells, and the latter fails to acquire a prominent improvement in energy efficiency (EE). In this paper, a time and frequency domain interference coordination is proposed. Dynamic Point Blanking (DPB) is introduced into ABS scheme to reach a tradeoff between fairness and EE. In time domain, macrocells reduce transmission power during ABSs. In frequency domain, DPB scheme dynamically mutes the strongest interference of coordinated points to further mitigate interference. When the novel DPB is adopted, firstly, the muting pattern is designed to determine DPB users according to coordination. Then a cloud cooperated cellular network (C-HetNet) is introduced, in which small power nodes under a macrocell are connected to cloud radio access network (C-RAN) to operate with the macrocell. C-RAN mutes some macrocells' resource blocks (RBs) used by DPB users. The simulation results demonstrate that the proposed DPB-ABS scheme can increase the total network EE excellently while ensuring fairness between macrocells and picocells.

作者： Yanbo Wang Caili Guo Xuekang Sun Chunyan Feng Beijing Key Laboratory of Network System Architecture and Convergence Beijing University of Posts and Telecommunications Beijing China

In overlay cognitive radio network, the available spectrum for secondary users are dynamically grabbed from a wideband of hundreds megahertz by spectrum sensing, which leads to remarkably differential path loss among different frequencies according to propagation theory. Adjusting the global path loss of cognitive relay system through spectrum allocation can serve nontrivial increment to the performance of multi-relay selection. In this paper, we propose a novel scheme combining multi-relay selection with spectrum allocation in the cognitive radio relay system to obtain maximum signal to noise ratio (SNR) at the receiver, called SAMS (spectrum allocation and multi-relay selection). Given the available frequencies, we first search all the possible resolutions for spectrum allocation, then make multi-relay selection under each possible spectrum allocation resolution to optimize the SNR value at the receiver. Finally, we choose the largest SNR, achieve the corresponding spectrum allocation resolution and also figure out the selected relays. Compared with conventional multi-relay selection scheme (CMS), simulation results demonstrate that our proposed scheme has a 4dB-increment of SNR value at the receiver.

A smart vertical handoff decision algorithm based on queuing theory is proposed in this paper. Vertical handoff in heterogeneous wireless network is crucial to the future wireless communication. The algorithm formulates the heterogeneous wireless area and handoff procedure using queuing theory and proposes a new network selection index called new handoff blocking probability to evaluate the network performance. A RSS-based mechanism is considered to avoid the Ping-Fong effect. Also the network architecture is regulated to manage the wireless resource effectively. The experimental results show that the proposed algorithm outperforms the traditional algorithm with low handoff blocking probability and a better load balance of the whole wireless environment.

Cell range expansion (CRE) technique has been introduced into heterogeneous networks (HetNet) to perform load balance. However, small cell CRE user equipments (UEs) may suffer severe downlink (DL) co-tier interference and cross-tier interference in dense small cell environment. In this paper, we present a joint clustering-based resource allocation and power control scheme to mitigate interference CRE UEs suffer. Firstly, we divide the dense small cells into different clusters by the graph coloring algorithm (GCA). Then we coordinate frequency resource allocation among different clusters and macrocells, which can better reuse resource blocks (RBs). After that, SBSs in some clusters reduce power to mitigate the co-tier interference. Meanwhile, in order to alleviate the cross-tier interference, a utility function combining interference and throughput is calculated to find the optimal transmission power of macro base stations (MBSs) by differential evolution (DE) theory. Finally, simulation results demonstrate that the proposed scheme can significantly improve the CRE UEs throughput with slight sacrifice of the macro throughput.

In the research of green networks, considering the base station (BS) density from the perspective of energy efficiency is very meaningful for both network deployment and BS sleeping based power saving. In this paper, we optimize the BS density for energy efficiency in cellular networks by the stochastic geometry theory. First, we model the distribution of base stations and user equipment (UE) as spatial Poisson point process (PPP). Based on such model, we derive the closed-form expressions of the average achievable data rate, the network energy consumption and the network energy efficiency with respect to the network load. Then, we optimize the BS density for network energy efficiency maximization by adopting the Newton iteration method. Our study reveals that we can improve the network energy efficiency by deploying the suitable amount of BSs or switching on/off proportion of the BSs according to the network load. The simulation results validate the theoretical analysis, and show that when the right amount of BSs is deployed according to the network load, the network energy efficiency can be maximized and the maximum energy efficiency is a fixed value once the network parameters are given.

The objective of the proposed work is to find the effects on the reading performance of 900 MHz radio frequency identification system (RFID) under the wireless interference. Experiments were carried out in full anechoic chamber avoiding the influence of wireless signal produced by the reflection. In order to simplify the analysis of the process of performance, single tone signal was selected as the source of wireless interference. The performance was measured in terms of change in the successful reading rate of tags and the interrogation range of the reader. Typically the performance of the RFID will decline due to the wireless interference. However in our experiment it was found that the unwanted signal can significantly improve the performance of RFID system when its power reaches a certain range. To explain this phenomenon, we analyze the tag circuit as well as the back-scatter link, and the ratio m was defined to characterize the degradation of reading performance. It was concluded that the results we calculate using the method we proposed was matched with the experimental results.

A tracker-based cache utilization strategy in CCN

IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC)

作者： Liu Hongbao Wu Muqing Hu Qian Peng Li Wang Ning Beijing Key Laboratory of Network System Architecture and Convergence Beijing University of Posts and Telecommunications Beijing Peoples Republic of China

One important feature of Content-centric networking (CCN) is to utilize built-in network caches to improve the transmission efficiency of content dissemination. In CCN, all nodes have the function of caching contents. Consequently, caches are ubiquitous and diverse. How to make full use of these caches to reduce the network load and the transmission delay has become a hot research topic in recent years. In order to speed up content distribution and improve network resource utilization, a cooperative caching strategy called Tracker-based Cache Utilization Strategy (TBCUS) is proposed in this paper. In TBCUS, an idea of partial centralized management of the caches is introduced into traditional CCN. Moreover, in order to alleviate the pressure that the incurred overhead imposes on network bandwidth, TBCUS divides the whole caching system into several sub-systems. Each of the sub-systems has a tracker server as the controller and some peers. The contents cached in a sub-system are transparent to each other through the coordination of the tracker server. Once a content request reaches to a sub-system, all the caches in the sub-system can be selected to respond to this request. While the traditional caching strategy in CCN is that only the caches on the delivery path can be used to respond to the content request. TBCUS improves the cache utilization and has higher cache hit ratio and lower transmission delay and network load compared with the traditional caching strategy.

Energy harvesting wireless sensor networks (EH-WSNs) have been widely used in various areas in recent years. Unlike battery-powered wireless sensor networks, EH-WSNs are powered by energy harvested from ambience. This change calls for new designs on routing protocols in EH-WSNs. This paper proposes a novel centralized clustering routing algorithm based on discrete particle swarm optimization (DPSO). The base station (BS) gathers status information from all nodes, then runs a modified DPSO algorithm to find the optimal topology for wireless sensor networks. The cluster heads election and member nodes attribution are considered as an overall problem and are optimized simultaneously. Simulation results show that the DPSO-based clustering routing has stronger ability to balance energy consumption among sensor nodes in EH-WSNs and increases the network throughput by 15% than sLEACH.

Spatial sharing (SPSH) is one of the most important merits in 60 GHz millimeter wave (mmWave) wireless personal area networks. Multihop architecture exhibits significant potential for concurrent transmission. In this study, we investigate the SPSH problem for single-hop and multihop architecture under the physical interference model. The minimum length schedule problem of satisfying the required traffic demand with the shortest time is formulated as the optimization problem. Concurrent scheduling and routing are jointly considered in the multihop case. To reduce the complexity of the computation, the column generation algorithm is employed to derive the optimal solution. The simulation results show that multihop architecture can enhance the network throughput by 20% to 30% compared with single-hop architecture.
