Wireless sensor networks (WSNs) are widely deployed in many fields nowadays. However, the limited energy storage ability of sensor nodes causes great detrimental effect on the performance of the WSNs. Energy harvesting has been proved as one of the promising ways to replenish the energy constrained sensors for prolonging WSNs lifetime. Another exacerbated problem introduced by non-uniform energy distribution and nonoptimal energy management in WSNs also causes great challenge to WSNs. For realizing the efficient energy utilization and improving the performance of energy harvesting enabled WSNs, two transmission management schemes, Markov decision based packets aggregation allocation (MDPA) and partial Kalman filter with best-match aggregation (PKBPA), are proposed respectively in this paper. MDPA focuses on the node's own energy capabilities to decide the packets number for aggregation, while PKBPA decides the number of packets to be aggregated and transmitted based on the estimated energy state information of the node and its next hop. Simulation results show that the PKBPA scheme outperforms other schemes, especially when the energy is insufficient for the packets transmission.

The emerging dense heterogeneous networks comprising different types of small cells enable consumers to employ multiple radio access technologies to communicate. In such a dymica network environment, development of robust and self-adaptive network selection mechanisms is required to satisfy the growing demand on ubiquitous network access. Besides, the energy consumed at wireless interface accounts for the great proportion of the total energy consumption of user devices and the battery lifetime has become a important factor affecting quality of experience (QoE). Hence in this paper, we propose an adaptive network selection approach where each user autonomously choose desired wireless network interface that offers the best energy-quality tradeoff. For this purpose, we adopt an attractor selection model, which is developed from autonomous and adaptive behavior of biological systems. The high adaptability to fluctuating network environment and the simple control rules allow users to dynamically select the best network that provide satisfactory QoE while achieve a acceptable device battery lifetime. © 2015 IEEE.

In this paper, a joint reducing energy consumption and improving quality of service scheme for the migration of virtual network resources is proposed. This migration algorithm reflects the state of the virtual network resources dynamically, and the algorithm consists of two parts: Energy-efficient Module and QoS Module. Each Module is responsible for a specific function. The Energy-efficient Module is responsible for the energy consumption of servers, and the QoS Module is responsible for the quality of network service, and it can optimize the target nodes with the relative cost of migration. The efficient and QoS-Aware migration algorithm take the energy consumption and the quality of service into account. The simulation results show that the proposed algorithm can reduce energy consumption to the servers, improve the quality of experience, reduce the latency and achieve the objectives of managing of virtual network quickly and easily. © 2015 IEEE.

Dense heterogeneous networks are deployed for future wireless communication to meet the explosively increasing traffic demand. However, the network densification leads to a great amount of energy consumption especially the operation energy consumption. In this paper, we consider cooperative Base station (BS) operation in downlink dense heterogeneous networks consisting of one macro BS and several small cell BSs (SBSs). Two sleep modes operating at different time scales are proposed to save energy based on the features of wireless traffic, i.e., traffic is rather stable in long term but fluctuates in short term. When work in deep sleep mode, physical infrastructure of SBSs like baseband and circuits are switched off. In opportunistic sleep mode, SBS optimally switch off some antennas and associated physical components and perform cooperative transmission for users. The proposed cooperative BS sleep strategy for dense heterogeneous networks takes both traffic features and cooperation transmission into account, and can achieve great energy saving while guarantee the quality of service (QoS) of users. © 2015 IEEE.

The performance of large-scale cognitive radio (CR) networks with secondary users self-sustained by opportunistically harvesting radio-frequency (RF) energy from nearby primary transmissions is investigated. Using an advanced RF energy harvester, a secondary user is assumed to be able to collect ambient primary RF energy as long as it lies inside the harvesting zone of an active primary transmitter (PT). A variable power (VP) transmission mode is proposed, and a simple energybased opportunistic spectrum access (OSA) strategy is considered, under which a secondary transmitter (ST) is allowed to transmit if its harvested energy is larger than a predefined transmission threshold and it is outside the guard zones of all active PTs. The transmission probability of the STs is derived. The coverage probabilities and the throughputs of the primary and the secondary networks, respectively, are characterized. The throughput can be increased by as much as 29%. Simulation results are provided to validate our analysis. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2015.

A tracker-based cache utilization strategy in CCN 26

A tracker-based cache utilization strategy in CCN

26th IEEE Annual International Symposium on Personal, Indoor, and Mobile Radio Communications, PIMRC 2015

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. © 2015 IEEE.

In this paper, the measurements of 2 × 2 MIMO channel were performed at 2.6 GHz with 20 MHz bandwidth along the Harbin-Dalian passenger dedicated railway line. To improve the accuracy of multipath searching, we propose a multipath components (MCPs) extraction method based on this measurement, using the statistical properties of the data to reduce dependence on certain specific parameter. Numerical analyses of small and large scale parameter fading characteristics in hilly terrain scenarios are presented such as channel impulse response (OR), power delay profile (PDP), time delay spread, Doppler spread, path loss and shadow fading which are significant to the study of wireless channel modeling in specific scenario applied in LTE-R system. All these analyses promote the verification and evaluation of wireless wideband communications on LTE-R system in high speed railway. © 2015 IEEE.

The main characteristic of the wireless medium is its broadcast nature, i.e., a unicast packet (destined for one specific node) is actually a one-hop broadcast packet to neighbors. However, the traditional routing transmit packets on the best path which is broken easily in practical dynamic environments and when the traffic rate is high. Thus, it leads to many retransmissions for route discovery and in turn gives a rise to heavy packet losses and long delays. In this paper, we propose a stable opportunistic routing mechanism of network layer for multi-hop ad hoc networks referred to as SOR which takes advantage of broadcast nature of wireless media. In SOR, two forward lists (FL) which contain the candidate forwarders are generated upon the route request and route reply messages to take advantage of path diversity, mitigate the redundant packets in the network and adapt to higher traffic rate. In order to reduce redundant packets in the network, we utilize the repeated packets forwarded by the candidate forwarders as confirmation. With simulations in NS-2 platform of several traffic rates and various channel state conditions, the superiority of SOR is verified over traditional routing protocol (AODV) and extremely opportunistic routing (ExOR) in throughput, end-to-end latency, packet delivery rate and adaption to dynamic radio environment. © 2015 IEEE.

Content-centric networking (CCN) is a new Internet architecture, relies on in-network caching to achieve an efficient and reliable content distribution. However, the existing forwarding strategy cannot fully sense the location of cache, because it is rely on the ports of routing table. In this paper, we propose a Bidirectional Cache Locating Algorithm based on Ant Colony Optimization (BCLA) using bidirectional ants to diffuse and exploit multiple content copies. One direction of ant called Announcing Ant is responsible for advertising the information of cached content to neighbors in a limited area, the other side, including Probing Ant and Updating Ant, are responsible for seeking cached content for the routers outside the area. Our goal is to find the optimal cache, and making efficient utilization of available cache resources within a certain area. Extensive experiments have been carried to evaluate BCLA against other forwarding strategies. The simulation results prove that BCLA outperforms other strategies in the content delivery latency, cache hit ratio, as well as the path stretch. © 2015 IEEE.

Compute-and-Forward (C&F) has been proved to be an efficient approach for multiuser, multihop wireless networks. It allows intermediate relays to infer and forward linear combinations of the transmitted messages, in order to achieve high computation rate. The coefficient selection for each relay is a shortest vector problem (SVP). The most common solutions for such a problem are exhaustive search and the Lenstra-LenstraLovsz (LLL) lattice reduction. The former has a high complexity and the latter proves to be suboptimal for large numbers of users. In this paper, we propose two novel algorithms, of which one can be regarded as a simplified version of the exhaustive search, while the other one selects the coefficients iteratively. Numerical results reveal that both methods achieve the same computation rate as the exhaustive search with much lower complexity. Both outperform the LLL algorithm (especially with a large number of users), and the complexities are lower than the LLL except in the very high SNR region.
