    An Asymmetric Key-Based Security Architecture for Wireless Sensor Networks

    In spite of previous common assumptions about the incompatibility of Public Key Cryptography (PKC) schemes with Wireless Sensor Networks (WSNs), recent works have shown that they can be utilized for such networks in some manner. The major challenge of employing a PKC-based scheme in a wireless sensor network is posed...

    A Lightweight NEMO Protocol to Support 6LoWPAN

    The NEtwork MObility (NEMO) and IPv6 over Low power WPAN (6LoWPAN) protocols are the two most important technologies in current networking research and are vital for the future ubiquitous environment. In this paper, the authors propose a compressed packet header format to support the mobility of 6LoWPAN. Also, a Lightweight...

    Securing Layer-2 Path Selection in Wireless Mesh Networks

    The current paper standard of 802.11s has defined routing for Wireless Mesh Networks (WMNs) in layer-2 and to differentiate from layer-3 routing, it termed layer-2 routing as path selection. The Layer-2 Path Selection (LPS) mechanism is fully specified in the paper of IEEE 802.11s for WMNs. However, routing with security...

    E-EDPPS: Enhanced an Energy-Efficient Data Privacy Protection Scheme for Wireless Sensor Networks

    In this paper, the authors investigate the facts of ensuring secure sensed data in a balanced energy network backbone, and propose Enhanced an Energy-Efficient Data Privacy Protection Scheme for wireless sensor networks (E-EDPPS). In Wireless Sensor Networks (WSNs), sensors may be deployed in an unpredictable environment where a limited energy...

    A Set-Top Box With Virtual Platform Support for QoS Management in IMS Based Multiple Provider Networks

    Set-Top Box (STB) has evolved from being a device just sitting on top of a TV shelf to a device providing a gateway to the Internet for a home network, receiving services from multiple content providers, and enabling and ensuring Quality of Service (QoS) for the streaming media. IP Multimedia...

    ATLAS: A Traffic Load Aware Sensor MAC Design for Collaborative Body Area Sensor Networks

    In collaborative body sensor networks, namely Wireless Body Area Networks (WBANs), each of the physical sensor applications is used to collaboratively monitor the health status of the human body. The applications of WBANs comprise diverse and dynamic traffic loads such as very low-rate periodic monitoring (i.e., observation) data and high-rate...
