Problems solved by technology
However, in the actual dynamic scheduling process, long computing time and high energy consumption often occur. Therefore, dynamic scheduling in RWSN needs to comprehensively consider multiple QoS (Quality of Service, quality of service) performance such as task completion time and energy consumption. indicators, that is, to satisfy time constraints and energy constraints
[0005] However, in the prior art, when adding or removing tasks, such as messages, in the RWSN, the time constraints and energy constraints are usually violated, that is, the problems of long time and / or high energy consumption will occur

Embodiment Construction
[0054] In the prior art, any addition of tasks or messages after reconfiguration may violate time constraints and / or energy constraints. Consumption, so that the system is time or energy infeasible, so scheduling of these tasks or messages can no longer be done.
[0055] In the present invention, when adding messages, system feasibility can be maintained, and the system feasibility refers to feasibility in time and energy, that is, these messages can be transmitted normally, and the transmission of each message can meet time constraints and energy constraints. In order to achieve the above object, the present invention proposes following three corresponding solutions:
[0056] (1) WCTT (Worst Case Transmission Time, worst case transmission time) that splits messages on multiple channels, which is called Balance Strategy.
[0057] (2) Increase the transmission cycle of messages on multiple channels, which is called a dilution strategy (Dilute Strategy).
[0058] (3) The combi...

The invention provides a transmission scheduling method and system of a message in RWSN under time and energy constraint. Any added or removed message can be effectively managed through the selectionor combination of adopting a balance strategy and a dilution strategy, enabling a new channel, forbidding a channel, increasing the period of the message with the lowest priority, and deleting the message with relatively low priority, and the feasible and optimized task scheduling is realized.
Description
technical field [0001] The present invention relates to a message transmission scheduling method and system in RWSN (Reconfigurable Wireless Sensor Networks, reconfigurable wireless sensor network), more specifically, to a message transmission scheduling method and system in RWSN under time and energy constraints. Background technique [0002] WSN (Wireless Sensor Networks, wireless sensor network) is a sensor network composed of a large number of sensor nodes deployed in the monitoring area in a self-organizing and multi-hop manner, with typical characteristics such as large-scale, low power consumption, low cost and self-organization , can be widely used in many fields such as environmental monitoring. In WSN, sensor nodes are powered by disposable batteries, and sensor nodes cannot complete complex applications alone due to their low computing power and limited energy. Therefore, the gateway needs to decompose the application program into multiple tasks with priority rel...
