In many studies of amplify-and-forward cooperative networks, a harmonic mean approximation has been used for the instantaneous signal-to-noise ratio of each dual hop relaying branch. This approximation overestimates the signal-to-noise ratio and results in a lower bound for the performance metrics, such as outage probability and average error probability. In this paper, a framework is introduced to obtain a tight upper bound for these performance metrics, as a function of harmonic mean approximation. It is shown that this upper bound is the tightest possible one among all harmonic mean related approximations. This bound is derived by modifying the same analysis used in the previous studies to compute the lower bound, without increasing the order of computational complexity. Numerical results and simulations show that the proposed upper bound for the performance metrics well follows the exact values.

3GPP is investigating uplink transmit diversity alternatives for HSUPA. This paper focuses on a transmit diversity scheme using switching between two transmit antennas without additional feedback information. The special focus of this paper is on various non-ideal conditions that occur in real implementations, such as antenna imbalance, correlation and the existence of multiple different SATD algorithms in the network simultaneously. The studies show that transmit antenna correlation somewhat decreases performance but still keeps gains over the baseline, antenna imbalance reduces situations where the switching is feasible and that using a mixture of algorithms can bring down the gains.

Wireless Sensor Networks (WSNs) allow for untethered sensing of the environment. It is anticipated that, within the next few years, sensors will be deployed in a variety of scenarios, ranging from environmental monitoring to health care, from public to private sector and other areas. This paper investigate the utilization of receiver-based Medium Access Control (MAC) protocol in enhancing the performance of routing protocols such as IETF ROLL's RPL. Receiver-Based MAC (RB-MAC) is a preamble-sampling MAC protocol which dynamically elects the next-hop among a number of potential relay neighbors, based on current channel conditions and status of the sensor nodes. The proposed scheme is resilient to lossy links by nature, and hence reduces the number of retransmissions. We show by analysis how it outperforms the state-of-the-art sender-based preamble sampling MAC protocols in terms of energy and delay.

Detailed passive analysis of TCP sender behaviour requires accurate identification of congestion events. Previous tools that attempt to provide such information do not incorporate the behaviour of recent operating systems and TCP features and are therefore of little use to researchers analysing contemporary TCP traffic. In this paper, we present a new tool for identifying and classifying TCP congestion events from a passive packet trace, called tcpcsm, which understands modern operating system TCP behaviour. We discuss the major problems that occur when passively identifying TCP congestion events and describe how tcpcsm solves them. We also show that tcpcsm is more accurate than previous tools using a series of controlled experiments involving a variety of operating systems.

In this paper, we address the problem of allocating users to radio resources (i.e. subcarriers) in the downlink of an OFDMA system. In particular, we consider a multi-format resource allocation problem (MF-RAP) in which the link adaptation adjusts the spectral efficiency for each user-subcarrier pair, i.e. for each radio link, in order to minimize the total transmission power while fulfilling a rate request for each user. We propose an integer linear programming (ILP) formulation of the problem and exhaustively discuss the computational complexity. Specifically, we prove that the problem is NP-hard in the strong sense and demonstrate that it is hard to be approximated in polynomial time within a constant factor. Hence, we present heuristic approaches that achieve “reasonably good” solutions in the general case. Computational experiences show that, in comparison with a commercial state-of-the-art ILP optimization solver, the proposed algorithms are effective in terms of solution quality and CPU times.

The ITU-T Recommendation G.805 is a telecommunication standard providing a generic functional architecture for transport networks and serving as the basis for several others networking and management specifications. Due to its fundamental importance, it is essential for this recommendation to be clear, complete and unambiguous, thus eliminating the spread of problems for all its using documents. This article employs an ontology-based systematic evaluation to verify the aforementioned characteristics on the ITU-T G.805 standard current documentation. Moreover, it discusses a number of ontological problems identified by this evaluation. Finally, the article illustrates with fragments of a well-founded reference model for the same domain, how these identified problematic situations can be addressed in a representation artifact.

Cognitive Radio (CR) is an essential technique for the future generation green communication paradigm owing to its inherent advantages of adaptability and cognition. The compulsory spectrum sensing is a critical component to facilitate systems co-existence. In this paper, we propose a new Time-Division Energy Efficient (TDEE) sensing scheme in which the sensing period is divided into an optimal number of timeslots and each Secondary User (SU) is assigned to detect a different channel in one time-slot. An important advantage of TDEE is that the SUs do not need to exchange the control messages for the acknowledgement of a successful cooperation, leading to substantial energy saving without compromising sensing accuracy. Both homogeneous and heterogeneous networks are investigated with respect to the intrinsic trade-off between spectrum efficiency and energy-efficiency. Illustrative results demonstrate that the proposed TDEE is able to achieve much lower energy consumption compared to the existing mechanisms.

In this work we add a training phase to an Impairment Aware Routing and Wavelength Assignment (IA-RWA) algorithm so as to improve its performance. The initial IA-RWA algorithm is a multi-parametric algorithm where a vector of physical impairment parameters is assigned to each link, from which the impairment vectors of candidate lightpaths are calculated. The important issue here is how to combine these impairment parameters into a scalar that would reflect the true transmission quality of a path. The training phase of the proposed IA-RWA algorithm is based on an optimization approach, called Particle Swarm Optimization (PSO), inspired by animal social behavior. The training phase gives the ability to the algorithm to be aware of the physical impairments even though the optical layer is seen as a black box. Our simulation studies show that the performance of the proposed scheme is close to that of algorithms that have explicit knowledge of the optical layer and the physical impairments.

AR (Augmented Reality) on mobile device is beyond providing simple additional information. Moreover, it has extended its range to variety domains. The latest AR service for device recognition uses POI (Point of Interest), GPS (Global Positioning System) or digital compass. These technologies could not be applied well in home and office environments, because it is difficult to recognize small and uniform shaped devices like industrial products. Nowadays, other methods of device recognition have been widely studied. One is tracking device features. This makes feature model and then compares feature model with trained model. The other is that using bar code or RFID. Such methods are hard to get into user-space because dynamic device status, device sensing or recognition could not be made into trained model. Therefore, in inner space like home or office, AR has not been used widely compared to outer space. In this paper, we propose new concept of technology about device recognition using network profile information though a mobile camera interface. In addition, we provide preview method about device's service, contents, and real-time status information so that users can use faster, more intuitive user-interface in mobile devices. We implement the system of media server and renderer to share digital contents. This provides intuitive interaction for contents sharing just using camera preview.

This paper presents a performance study of a low power non-coherent multi-band IR-UWB system based on energy detection for future wireless high data rates communications. The studies presented in this paper are based on the statistical multipath model of the UWB channel proposed by the IEEE 802.15.3a task group. A new simple model of the received signal is proposed. The main objective of this model is to evaluate the effects of combinations between paths in the propagation channel. The statistical characterization of the received signal and that of its energy were given for a system based on energy detection. The communicating system performance was evaluated in terms of average channel capacity and data rate. The obtained results permitted us to evaluate the advantage of the frequency demultiplexing approach adopted for the MB-OOK UWB transceiver1.
