    CROMA - A Slotted Mac Protocol for MANETs with Multislot Communications

    TDMA based MAC protocols can provide a very good utilization of the shared radio resources, especially at high input loads, in synchronized Mobile Ad hoc NETworks (MANETs). Global positioning systems like GPS or GALLILEO should provide a very good timing accuracy for synchronization of nodes. This paper presents a medium...

    Interaction Between Hidden Node Collisions and Congestions in Multihop Wireless Ad-Hoc Networks

    In this paper, the authors study the performance of the IEEE 802.11 MAC protocol and its impact on the transport layer performance in multi-hop wireless ad-hoc networks. They focus on the hidden node problem that effects heavily the end-to-end delay and the packet loss probability. Through a mathematical analysis, they...

    On Hybrid Collision Control for IEEE 802.11 Ad-Hoc Networks

    The authors present in this work a new mechanism based on an innovative hybrid approach for traffic and collision control in wireless ad hoc networks. They combine the well known equation based technique with the measurement based one in a way to obtain a predictive state of the network. Combining...

    A Secure and Efficient Authenticated Diffie-Hellman Protocol

    The Exponential Challenge Response (XRC) and Dual Exponential Challenge Response (DCR) signature schemes are the building blocks of the HMQV protocol. The authors propose a complementary analysis of these schemes; on the basis of this analysis they show how impersonation and man in the middle attacks can be mounted against...

    Dimensioning WiMAX Mesh Networks With Multiple Channels

    The IEEE 802.16 standard defines two modes of operation: Point-to-Multi-Point (PMP) and MESH mode. In the PMP mode, Subscriber Stations (SS) connect to the Base Station (BS) in single hop transmissions. Mesh mode, however, allows SSs to communicate with each other, thus forming a wireless multihop mesh network. The standard...
