We present here a fundamental understanding of the capacity of wireless ad hoc networks. Under the assumption that all interference is essentially regarded as noise, we try to answer the question: “What is the lower bound on network capacity under a certain power assignment and nodal distribution?” We give two quantitative lower bounds: one is measured in bps (bits per second), the other is measured...
This paper studies the maximum throughput that can be supported by a given wireless mesh backhaul network, over a practical CSMA/CA medium access control (MAC) protocol. We resort to the multi-commodity flow (MCF) formulation, augmented with the conflict-graph constraints, to jointly compute the maximum throughput and the associated optimal network dimensioning; while use a novel approach to take...
RS232 interface executes the role of Transportation and Communication, which has became the important interface between MCU of embedded system and peripheral equipment. Because RS232 mainly work in bottom of communication protocol, so it is important to protect the infrastructure of RS232. In test, pulse double electromagnetic is pulled into RS232 data transmission lines by coupling clamp, simulated...
