We study the problem of revenue management in a cognitive spectrum underlay network, where the primary user chooses the bandwidth and tolerable interference levels for the secondary users. We show that the interference received by each secondary user is the same in a large system regime, and a simple pricing scheme achieves the efficient resource allocation at the market clearing equilibrium. We further show that the key for the primary user to maximize revenue is to consider the secondary users' power-interference elasticity, which is a new concept proposed and is different from all elasticity concepts used in the previous networking literature. When this elasticity is negative (positive, respectively), the primary user should increase (decrease, respectively) the bandwidth and tolerable interference level to increase revenue.

This paper investigates QoE (Quality of Experience) of MVV (Multi-View Video) and audio transmission over IP networks. Unlike previous works that mainly discuss MVV transmission from aspects of video codecs, we study MVV and audio transmission under various IP traffic and delay conditions by experiment. We compare two schemes: a scheme that the user watches a single viewpoint, and the one that he/she can choose one viewpoint from many viewpoints. At the same time, we perform a user study which helps us to understand the user behavior in the MVV system under those conditions. As a result, we show that high QoE can be achieved when the user can change the viewpoint with low load traffic and delay.

Wireless Sensor Networks (WSN) are mainly characterized by dense deployment of sensor nodes. Due to the spatial correlation between sensor nodes and constrained resources of nodes, Spatial Correlation-based Mobile Agent Routing (SCMAR) algorithm is proposed to exploit such correlation for the realization of advanced efficient Mobile Agent routing protocol in order to estimate the event with energy efficient way. The theoretical framework of SCMAR is developed to suppress redundancy information collection under a distortion constraint for reducing the energy consumption without compromising the estimated reliability achieved at the sink. Finally, Simulation results show that SCMAR achieves better performance than existing Mobile Agent Routes for Data Fusion (MARDF) routing algorithm from perspectives of energy consumption in a variety of correlated data gathering applications.

Many existing routing protocols for wireless mesh networks (WMNs) are based on minimal hop counts and cannot fit WMNs because they did not take into account congestions in networks. Although other multipath routing protocols use node- or link-disjoint routes, they are still based on minimal hop counts and may even cause extra congestion into networks. This is because a node-disjoint path may contain link-joined segments, which could be congested as many flows use them to forward packets. This paper proposes two congestion-aware routing metrics to enable routing protocols to consider congestion issues by exploring information available at the data link layer. One metric is called buffer occupancy ratio which considers the congestion status of nodes. The other metric is called successful frame sending rate which considers the congestion status of links. These two metrics are used to design a multipath routing protocol to find multiple less congested routes to improve network throughput. The simulation study has shown that the proposed routing scheme achieves significant throughput improvement with much more reliable packet delivery.

In a wireless mesh network (WMN) connected to the outer infrastructure such as the Internet, one or more gateways to connect to the outer network as well as surrounding nodes may frequently be congested by concentration of traffic from mobile stations. To resolve the congestion, we propose a new congestion control scheme for layer 3 WMNs. In the proposed scheme, nodes composing WMN backbone (MNs: mesh nodes) monitor their transmission queue periodically and detect congestion. When an MN detects congestion, it identifies MNs which inject a dominant amount of traffic causing congestion, and sends a congestion control message to these MNs. When the MNs receive the congestion control message, they control the bandwidth of the traffic toward the congested MN. We have performed simulation of the proposed scheme using a simple network model and evaluated the effect of congestion control. We have shown that the proposed method is effective to reduce average queue length of the bottle-neck MN and to improve the total throughput significantly.

The introduction of Common Radio Resource Management (CRRM) facilitates the coordination of multiple overlapped Radio Access Technologies (RATs). A Network Controlled Cell Breathing (NCCB) RAT selection algorithm is proposed in the literature for combined GSM/UMTS networks. The setting of a proper path loss threshold is a key issue in the NCCB algorithm. In this paper, the relationship among overall downlink data throughput, throughput fairness and path loss threshold is studied. It is found that in some cases, an optimum path loss threshold value can be found to achieve better performance in terms of both overall throughput and throughput fairness. However, in other cases, a tradeoff has to be made between the overall throughput and the throughput fairness.

This paper proposes a concept to construct a Traffic-Localized and Resource-Efficient tree-based architecture to support the delivery of an SVC-encoded live video streaming onto a Public-Shared Network. A Public-Shared Network consists of a large number of bandwidth sharable devices, such as sharable APs in a FON network. The SVC-encoded video streaming is employed to provide the smooth access of video streaming for clients in heterogeneous networks, and it consists of several sub-layer streams. To enable a smooth decoding on the client, the difference of the time to receive the corresponding sub-layer streams should be kept as small as possible (synchronization issue). Otherwise, the client may not able to decode the live streaming. The architecture is constructed by grouping the sharable APs and the clients by use of trace route information. The proposed mechanism is evaluated by the NS2 simulator. Simulation results indicate that the proposed mechanism is able to deliver the sub-layer streams in a timely manner to each client for smooth decoding. Furthermore, the proposed grouping mechanism is also very effective in saving the link bandwidth. Thus, the average bandwidth consumption rate of all links obtained by the proposed mechanism is much better (only about 8.93%) than that of random grouping.

SELENE (Selenological and Engineering Explorer) is a Japan's lunar probe which was launched and injected into the lunar polar orbit in 2007. The Main Orbiter of SELENE named Kaguya has separated the Relay Satellite: Rstar (Okina). We have executed four-way Doppler measurements which determined the orbit of Kaguya aviating above the lunar far side. The ground station up-links ranging signals, and the relay satellite transponder on Rstar (RSAT-1) relays the carrier waves to Kaguya. Then the transponder on Kaguya (RSAT-2) receives the signals and returns to Rstar, and down-linked to UDSC. Three of four receivers through four-way links acquires signals and tracks Doppler frequency shift with phased lock loops. For that purpose, the receivers should be locked sequentially under the condition of large Doppler shift due to mutual velocities of three moving bodies. The receivers were designed in consideration of the above condition and system operability. Eventually, our system has realized the first case to track two fully moving links between the lunar orbiters and carried out Doppler measurements. Results of the orbit determinations for Kaguya above the lunar far side have shown the anomaly distributions of the gravity fields which could be scarcely found by the conventional two-way RARR methods.

In this paper, the human body effect on indoor localization is evaluated based on experiments. Radio Frequency Identification (RFID) technology is used for this localization system. The location of a RFID reader is estimated based on the known locations of the RFID tags attached to the ceiling with 60 cm separation. Two cases of experiments are considered. For the first case, the RFID reader is attached to the camera tripod and the second case, it is attached to human body. Then, two simple location estimation methods are employed. To evaluate the effect of human body on the localization, the results of location estimation with and without human are compared. The experimental results illustrate that the human body affects the location estimation in some certain. However, the error of location estimation is still less than 50 cm which is applicable for some indoor applications.
