In real-time embedded systems, periodic messages need to be transmitted at the expected time because of timing sensitive requirements. In this paper, we take advantage of the characteristics of UM-BUS, a novel serial bus with the capability of multi-lane concurrent transmissions, and investigate the scheduling problem to reduce the deviation to the expected completion time of messages. By configuring...
Predictable message transmission is the primary requirement in networked safety critical embedded systems design. In these systems, delay jitter has been proven to be a critical factor that must be considered. For periodic messages, minimizing the delay jitter means messages should be transmitted at the expected time in every period. In this paper, we investigate the scheduling problem to reduce the...
In mobile ad hoc network (MANET), multiple QoS (Quality of Service) routing is the process for establishing the path which is from the source to the destination with multiple QoS constraints. Multiple QoS constraints is one in which the delay, delay jitter, bandwidth and cost should satisfied the pre- specified bounds. The paper discusses the QoS routing problem with multiple QoS constraints, deals...
