    One of most critical issues in power-constrained wireless sensor networks is to maximize the network lifetime. Recently, studies have been made on scheduling sensor activity to prolong network lifetime. In this paper, we address the maximum set covers (MSC) problem to maximize the network lifetime and propose an energy-efficient sensor scheduling algorithm for the MSC problem based on the branch a...

    The channel state information (CSI) of all links should be available at all nodes for cooperative strategies design in relay networks. However, many channel estimation methods for amplify-and-forward (AF) relay networks only estimate a compound CSI of source-relay-destination (S-R-D) link. In this paper, we propose a channel estimation scheme for destination to disintegrate the CSIs of S-R and R-D... View full abstract»

    Coalitional game theory is a promising tool for analyzing the dynamics of networks that implement cooperative protocols. In this paper, we examine the stable outcomes of a self-organizing cooperative network based on decode-and-forward relaying, namely, orthogonal (ODF) and non-orthogonal decode-and-forward (NDF) relay networks. A coalitional game theory approach is formulated to examine how coope... View full abstract»

    This paper presents a low-complexity incremental (LCI) algorithm for target positioning and tracking in wireless sensor networks. The proposed positioning scheme calculates the estimated location of a target as a nonlinear least squares (NLS) problem based on the distance estimation and solves the optimization problem in an iterative manner using the LCI algorithm. In the decentralized scheme, a p... View full abstract»

    As IEEE 802.11 matures and other wireless access technologies are introduced (such as IEEE 802.16e), the emergence of Internet Protocol as a de facto standard for transport allows users to have increasing choice about their mobile access. This effect will not only increase competition amongst cellular network providers it will also increase competition with other stakeholders and operators in the ... View full abstract»

    Wireless Service Providers (WSPs) aim to maximize the revenue from their investment in spectrum lease and infrastructure. In this paper, we present a simple model for enabling temporary wireless access for Secondary (unsubscribed) Users (SUs) along with Primary (subscribed) Users (PUs) to the same Base Station (BS), allowing SU access provided there is unutilized spectrum available at the BS after...

    This paper firstly puts forward a two dimensional interworking authentication model between 3GPP and WiMAX. In the proposed model, EAP-AKA method is adopted, and the first registered 3GPP AAA server in home domain (i.e. HPLMN, Home Public Land Mobile Network) takes charge of the responsibility of authentication for 3GPP/WiMAX UE by using authentication vectors (AV) obtained from HSS (Home Subscrib...

    All-IP mobile networks require a mechanism for enabling seamless handovers between different access technologies. For real-time services, such as voice and video, the Session Initiation Protocol (SIP) is becoming the leading signalling protocol in IP networks and has already been accepted as the signalling standard in 3G wireless systems. However, existing proposals for supporting mobility with SI... View full abstract»

    A parameter adaptively adjustable utility function based on the asymmetric sigmoid function is investigated for the non-cooperative power control game (NPCG) model in cognitive radio networks (CRN). Each secondary user (SU) can adaptively adjust the parameter to track along with the wireless interference environment for the optimal power strategy. From the fairness of view, a pricing function rela... View full abstract»

    Conventional polarizers usually include complicated corrugations and lossy insertions such as an iris, septa and dielectric slab, causing performance degradation and fabrication difficulties. At high frequencies, such fabrication difficulties and lossy components are limiting factors to achieving low costs and high performance. In this paper, a novel waveguide-type polarizer with an oval shaped cr... View full abstract»

    Abstract-We consider an asymmetrical two-way relay channel (TWRC) which consists of one relay node and two user nodes in this paper. In TWRCs, we can efficiently use the channel by using the network coding at the relay with the exclusive OR (XOR) operation. However, due to the nature of the XOR, the rate from the relay to a user node should be the same as the rate from the relay to the other user ... View full abstract»

    With the multitude of mobile communication devices supporting users, it is natural to expect that these devices would work ubiquitously anywhere and any time with high data rate support. 60 GHz is an obvious choice for the high data rate indoor communication. In this paper we present an holistic analytical model of 60 GHz link stability for indoor wireless networks. The model is built considering ... View full abstract»

    Modulation constellation extension (CE) schemes provide good peak-to-average power ratio (PAPR) reduction performance for orthogonal frequency division multiplexing (OFDM) signals. However, they usually require a complicated algorithm to find the optimal signal for transmission. In this paper, we propose a low-complexity CE scheme to reduce the PAPR of OFDM signals, in which some low-complexity co... View full abstract»
