Tie-line scheduling (TS) becomes a practical need for growing interconnection of regional power grids and the increasing integration of renewable energy. In electricity markets without a coordination organization, TS should be handled in a fully decentralized manner, where the impact of contingencies should also be considered for operational reliability. In this paper, the contingency-constrained...
In a low traffic wireless sensor network, the energy spent on nodes' state switching is non-negligible because of limited energy consumption on data transmission. In this paper, we proposes a centralized scheduling algorithm to minimize the nodes' state switching times by using TDMA and multichannel techniques. Our algorithm uses a receiver-based slot assignment strategy to assign consecutive slots...
We focus on the problem of links scheduling in heterogeneous wireless sensor networks. Links scheduling becomes more difficult due to the diversity of workload among sensor nodes. An improper links scheduling strategy will lead to high end-to-end delay and then diminish the data availability. We assume the energy cost of state transition cannot be ignored, especially for wireless multimedia sensor...
Wireless Multimedia Sensor Networks (WMSNs) are characterized by limited hardware resource, bandwidth and variable channel capacity. Most potential applications of WMSN require the network to reliably transmit large multimedia content to sink and to minimize the whole energy consumption. Energy and bandwidth are important factors which must be taken into account when schedule links. We use the data...
