Method for dynamic control of data packet length in wireless sensor network

The invention discloses a method for dynamic control of data packet length in a wireless sensor network, which comprises the following steps that: a request module of a source node transmits a request to a module for dynamic control of data packet length for transmission of a data packet to a target node; a link estimation module of the source node for dynamic control of data packet length estimates the link quality to obtain the optimal data packet length; if the length of the data packet transmitted on request is smaller than the optimal data packet length, the data packet is processed through polymerization and then identity addition or direct through identity addition and is then transmitted to the transmitting module of the source node, otherwise, the data packet is processes throughsegmentation and then identity addition and is then transmitted to the transmitting module of the source node; the data packet is sequentially transmitted to the receiving module and the module for dynamic control of data packet length of the target node, reduced through segmentation or polymerization, and then transmitted to the receiving module of the target node; and the aggregation response module of the target node transmits a response data packet to the source node.

Synergic inquiring method for local multiple S-mode secondary monitoring radar stations

The invention provides a synergic inquiring method for local multiple S-mode secondary monitoring radar stations, which is relevant to the distribution of S-mode secondary monitoring radar stations in the field of civil aviation, and relates to the technical field of civil aviation air traffic control and radar monitoring. In the method, at least two or more adjacent S-mode radar stations construct a cluster, the same inquiring code is assigned to the radar stations in the cluster, the cluster radar stations are connected with each other through a communication link, the monitoring target of each radar station in the cluster is classified, and target state information is subjected to synergic processing, so that synergic information can be communicated in time during synergic work; a plurality of radar stations with the same inquiring codes work synergistically, and selective inquiring of general-calling-free inquiring is realized; and the technical problem of incapability of monitoring a target caused by locking of a machine-carried response machine since the inquiring codes of the radar stations are the same is solved, the synergic monitoring of a plurality of radar stations is realized, and risks caused by insufficient inquiring codes is lowered.

Method, apparatus and platform for setting valid duration of file write-back process token

The invention discloses a method, a device and a platform for setting an effective duration of a file write-back process token. The method comprises the following steps: when a new session request sent by a file write-back process is received, obtaining a current write-back parameter of the file write-back process, wherein the new session request is sent after the file write-back process is interrupted; when the current write-back parameter is obtained, obtaining the effective duration of the token according to the current write-back parameter; creating a new session with the effective duration of the token according to the obtained effective duration of the token; allocating the new session to the file write-back process, so that the file write-back process continues to upload a file to a cloud storage space according to the new session. According to the method disclosed by the invention, different interrupted file write-back processes are set with reasonable different token durations to reduce the response times of a cloud storage platform to a token application request of the file write-back processes, reduce the interruption times of the file write-back processes and improve the concurrency of the cloud storage platform for processing the file write-back processes.
