    MIMO-Based Jamming Resilient Communication in Wireless Networks

    Reactive jamming is considered the most powerful jamming attack as the attack efficiency is maximized while the risk of being detected is minimized. Currently, there are no effective anti-jamming solutions to secure OFDM wireless communications under reactive jamming attack. On the other hand, MIMO has emerged as a technology of...

    Storing Shared Data on the Cloud via Security-Mediator

    Now-a-days, many organizations outsource data storage to the cloud such that a member of an organization (data owner) can easily share data with other members (users). Due to the existence of security concerns in the cloud, both owners and users are suggested to verify the integrity of cloud data with...

    A Proportional Fair Radio Resource Allocation for Heterogeneous Cellular Networks With Relays

    As a key technology in 4G-LTE, heterogeneous networks can effectively extend the coverage and capacity of wireless networks by deploying multiple micro-nodes on top of the conventional macro Base Stations (BS). The deployed micro-nodes differ in transmission power and processing capabilities, leading to new challenges in interference management, mobile association,...

    Joint Uplink and Downlink Optimal Mobile Association in a Wireless Heterogeneous Network

    Many technologies ranging from advanced physical layer antenna transmission schemes to efficient air-interface resource management schemes have been developed for spectrum efficiency improvement for the future wireless networks. However, most of these technologies quickly reach their theoretical limits without much room for further improvement. In order to meet capacity demands...

    SHARP: Private Proximity Test and Secure Handshake with Cheat-Proof Location Tags

    A location proximity test service allows mobile users to determine whether they are in close proximity to each other, and has found numerous applications in mobile social networks. Unfortunately, existing solutions usually reveal much of users' private location information during proximity test. They are also vulnerable to location cheating where...

    A Secure and Efficient Scheme for Machine-to-Machine Communications in Smart Grid

    Smart grid uses Machine-To-Machine (M2M) communication infrastructures and advanced control techniques for improved power distributions and management. Different types of communication schemes could possibly be used for smart grid applications, but need to be further explored in smart grid application scenarios. In this paper, the authors present the utilization of...

    Vulnerability and Protection for Distributed Consensus-Based Spectrum Sensing in Cognitive Radio Networks

    Cooperative spectrum sensing is key to the success of cognitive radio networks. Recently, fully distributed cooperative spectrum sensing has been proposed for its high performance benefits particularly in cognitive radio ad hoc networks. However, the cooperative and fully distributed natures of such protocol make it highly vulnerable to malicious attacks,...

    A Performance Metric for Message Forwarding Schemes of Massively Multiplayer Peer-to-Peer Based Networked Virtual Environments

    In this paper, the authors introduce a performance metric for use in characterizing message forwarding schemes of Massively Multiplayer Peer-To-Peer (P2P) based Networked Virtual Environments (NVE). Message forwarding, or routing, is the process by which peers send messages throughout an overlay. Different P2P NVE designs result in different message forwarding...
