    A Dynamic Spectrum Access Scheme for Unlicensed Systems Coexisting With Primary OFDMA Systems

    In this paper, the authors consider Mobile WiMAX and LTE as the future technologies for primary OFDMA systems and study Dynamic Spectrum Access (DSA) for unlicensed systems coexisting with primary OFDMA systems. They propose an effective DSA scheme that allows an unlicensed system to statistically and opportunistically access the whole...

    Preemption Mechanisms for Push-to-Talk in Ad Hoc Networks

    Using push-to-talk applications in ad hoc networks is not straightforward. There are no inherent mechanisms to support priority of the voice traffic, to avoid great jitter and packet loss in face of large background traffic loads. This paper presents three preemption mechanisms that can be applied to support push-to-talk traffic...

    Routing With Transmission Buffer Zones in MANETs

    Dealing with link breaks in MANETs is a challenge for the routing protocol. This paper proposes a mechanism to reduce the negative impact of link breaks on the routing. The transmission area of a node is divided into a safe zone close to the node and an unsafe zone (i.e....

    Personal Networks - An Architecture for 4G Mobile Communications Networks

    A personal network is a network architecture which builds on various wireless networking technologies. It is responsible for glueing these wireless networking technologies to serve users. This paper considers the co-operation of several key technologies to realize a personal network; namely Wireless Personal Area Network (WPAN), Wireless Local Area Network...

    The Economy of Redundancy in Wireless Multi-Hop Networks

    Due to frequent link failures in multi-hop wireless networks, redundancy can be an important feature. For example, when planning the structure of a backhaul mesh network for public access, it is common to introduce redundant nodes in the mesh network. These are called redundant, because they do not increase the...
