    SpaceOrthogonal FrequencyTime Medium Access Control (SOFT MAC) for VANET

    The IEEE is working on a MAC standard (802.11p) for VANET based on 802.11e. Although the access function of 802.11e supports QoS by using different backoff counters and interframe spaces for different QoS requirements, this reduces to a best effort service and low performance when the number of vehicles increases....

    1.25 GHz Path Loss Prediction Models for Multifloored Buildings

    In this paper, parameter statistics of path loss prediction models are presented for 1.25 GHz within multi-floored buildings. Parameters are extracted from analyzed data which was collected from measurements within three buildings. Buildings were chosen with specific considerations such as building footprint shapes and internal design. For the consideration of...
