TL;DR: In this article, a vehicle positioning navigation method of a network-less parking lot is presented, which comprises steps that an intelligent parking stall lock having a wireless communication function and a server are distributed on parking stalls of the parking lot, and the server and the Intelligent Parking Stl lock communicate; handshake request communication messages are automatically sent by the intelligent parking stl lock to mobile equipment of a driver, the sending time is further recorded, and message messages are sequentially replied and refused by the mobile equipment according to the acquisition time sequence of the handshake request communications messages.
Abstract: The invention discloses a vehicle positioning navigation method of a network-less parking lot. The method comprises steps that an intelligent parking stall lock having a wireless communication function and a server are distributed on parking stalls of the parking lot, and the server and the intelligent parking stall lock communicate; handshake request communication messages are automatically sent by the intelligent parking stall lock to mobile equipment of a driver, the sending time is further recorded, and the handshake communication messages are sequentially replied and refused by the mobile equipment according to the acquisition time sequence of the handshake request communication messages; the time from receiving to refusing the handshake request communication messages is recorded by the intelligent parking stall lock, and time difference of the two handshake request communication messages is calculated; the position of the driver is determined by the server according to the time difference and is sent to the mobile equipment of the driver, and driver position positioning is accomplished; real-time positioning and navigation for the driver are realized through repeating the previous steps. The method is advantaged in that cost is not only low, but also a positioning or navigation problem of the network-less parking lot is solved, precise and reliable positioning is realized, and the method is simple and easy.

TL;DR: Compared with the multichannel PD-CSMA with 3-way handshake in WSN but without conflict resolution algorithm, the new protocol's throughput is greatly improved and much of the resource is distributed to higher priority, realizing the better quality of service.
Abstract: Article History: Average cycle method is used to analyze the multichannel PD -CSMA with 3-way Handshake based on binary tree conflict resolution algorithm in WSN, getting the critical mathematical expressions of the system throughput, each priority traffic throughput, etc. The computer simulation results verify the correctness of the theory and show that the novel protocol has better performances than the anterior ones'. Compared with the multichannel PD-CSMA with 3-way handshake in WSN but without conflict resolution algorithm, the new protocol's throughput is greatly improved. On the basis of allocating the channel resource fairly, much of the resource is distributed to higher priority , realizing the better quality of service.

TL;DR: In this paper, a hand-shaking instruction simulation is used between a virtual computer monitor and a VMs to detect abnormal states in the virtual computer or the like and automatically detect the abnormal state.
Abstract: PURPOSE:To attain speedy correspondence by using hand-shaking between a virtual computer monitor and a virtual computer, permitting the virtual computer monitor to detect the abnormal state in the virtual computer or the like and automatically detecting the abnormal state. CONSTITUTION:The virtual computer 1 executes a specified handshake instruction 21 at every optional specified time. When the instruction 21 is executed, a specified handshake instruction simulation request 22 is informed to a virtual computer calculation means 4 in the virtual computer monitor 3. When the request 22 is informed to the monitor 3, the execution of the computer 1 is interrupted. The means 4 receiving the request 22 supervises that the instruction 21 is executed within the specified time after the execution of the computer 1 is started. When the means 4 receives the information of the request 22 within the specified time, the monitor 3 resets the supervisory time of the instruction 21 and resumes the execution of the instruction after the instruction 21. When there is no information of the request 22 in the means 4, it is judged that an abnormality state has occurred in the computer 1.

TL;DR: In this paper, an HTTPs (Hyper Text Transfer Protocols) handshake method, device and system, relates to the field of network transmission, and aims to solve the problems of low efficiency and high cost due to deployment of a Keyless server on a client side.
Abstract: The invention provides an HTTPs (Hyper Text Transfer Protocols) handshake method, device and system, relates to the field of network transmission, and aims to solve the problems of low efficiency andhigh cost due to deployment of a Keyless server on a client side. The method comprises the following steps: selecting a Keyless Server from at least two Keyless Servers to establish a connection whenan edge node receives a secure sockets layer (SSL)/transport layer security (TLS) handshake request of a user; and receiving a decrypted or signed message sent by the Keyless Server. The technical scheme provided by the invention is suitable for a CDN (Content Distribution Network), and an efficient and high-stability HTTPs handshake process is realized.
