This paper proposes a traffic flow control system at intersections for Internet of Vehicles by combining ideas from process scheduling in Operating Systems with a ticket mechanism. The paper models an intersection as a network of mutual exclusive resources and the vehicle flows as processes that access the resources. Two graph models: Flow Intersection Network and Flow Resource Allocation Network...
Recently there has been an increasingly use of SOA infrastructure. Most of business applications need the transaction management to guarantee the system consistency, typically by resource locks. High availability and performance of resource managers are extremely critical for business services. Researchs have shown that deadlock can be easily produced when multi-process try to access the shared resources...
The Physical Downlink Control Channel (PDCCH) is used to signal dynamic resource assignment information in the Long Term Evolution (LTE) system. In the presence of numerous active users, the system performance is likely to be hindered by shortage of control channel resource. In this paper, several simple algorithms are brought forward for making efficient PDCCH resource allocation. We first propose...
This paper proposes a novel semi-dynamic inter-cell interference coordination (ICIC) scheme for multi-cell OFDMA systems. The objective of the novel scheme is to strike a balance between ICI minimization and frequency reuse factor (FRF) maximization. Firstly, we divide cell-edge users into non-overlapping user groups based on users' geometry, and classify each group's available bandwidth, which includes...
