We introduce multi-phase project planning (MPPP) as the problem of finding an executable sequence of sets of actions to achieve all hard subgoals of all milestones and achieve hard and soft subgoals optimally, using fully-specified initial state, milestones and their subgoals, preconditions and effects of operators, rewards and penalties associated achievement and cancellation of soft subgoals, rewards...
Cellular networks can provide pervasive data access for smartphones, but also consume lots of energy, because the cellular interface has to stay in high power state for a long time (called long tail problem) after a data transmission. In this paper, we propose to reduce the tail energy by aggregating the data traffic of multiple nodes using their P2P interfaces. This traffic aggregation problem is...
We provide an improved bound for the expectation of the stationary delay under the maximum weight scheduling (MWS) policy in one-hop wireless networks. In the model, the interference of the links is characterized by an interference graph G=(V, E). For a vector μ ∊ R|V|+, let χf (G, μ) be the weighted fractional coloring number for the graph G under the weight vector μ. For an arrival rate vector λ...
Scalable video using Cloud Computing is a potential solution for the distribution of media content to a large number of users. This may occur over a heterogeneous network connected to devices with different capabilities and diverse set of users. Although some of the problems are well known and understood in information and network security, there is still a need to improve the existing solutions to...
A primary delay is the deviation from a scheduled process time caused by disruption within the process. Delay is controlled by timetable and shows the characters of random occurrence. Rail transit system is a complex system which is dynamic, nonlinear, self-adaptive, random-occurrence and schedule-controllability. The multi-agent method enlarges the range of computer applying in rail system. This...
A notion of logic time and logic time stamp are introduced to control running order for single-period and multi-periods simulation system. Then a synchronous startup schedule strategy is designed, and its technology essential and implementation flow are discussed. According to the time stamp and the simulation logic time of interactive data, the measurement and compensation method of time-delay in...
