Dynamic alliance mobile sensor network data processing task collaboration method

Abstract

The invention discloses a dynamic alliance mobile sensor network data processing task collaboration method, which is characterized by comprising the following steps: S1, establishing a task collaboration alliance; S2, sending the collected data to alliance collaboration nodes in a range by the alliance master node; and S3, jointly completing processing of the data and sending the processed data to the alliance affiliation node or the aggregation node by the alliance cooperation nodes, wherein the task collaboration alliance comprises at least one alliance master node and a plurality of alliance collaboration nodes, and the alliance master node comprises a first data acquisition module, a first processing module and a first communication module; each alliance cooperation node comprises a second communication module and a second processing module; and the first communication module is wirelessly connected with the second communication module. Complex data processing tasks of distributed mobile multimedia sensor nodes are reasonably decomposed, task load balance of collaboration nodes is reduced, and execution time and network energy consumption of the data processing tasks are reduced.

Description

technical field [0001] The invention relates to the technical field of sensor wireless communication, in particular to a dynamic alliance mobile sensor network data processing task coordination method. Background technique [0002] When mobile sensors perform tasks, the frequent departure and joining of task coordination alliances caused by the movement of nodes will waste limited resources, interrupt data processing tasks, cause task data retransmission, and affect the efficiency of task collaboration. Especially when the processing task is large, when the task is assigned to the node at one time, when the sensor node cannot complete the data transmission and the assigned task in time due to movement, the data transmission will be interrupted, and the image processing task data retransmission will be required , wasting limited communication and computing resources.
