Embodiment Construction
[0031] The present invention is directed to the TelosB platform with von Neumann architecture. The following takes the example of deploying a typical application program Blink (hereinafter also referred to as "basic version") for the first time and deploying the modified program CntToLeds (hereinafter also referred to as "updated version") as an example to further illustrate the present invention. The specific steps are as follows:
[0032] (1) The initial deployment of the wireless sensor network application Blink (that is, the basic version), including the following steps:
[0033] (1.1) Divide the source code of the basic version into replaceable components and system components, and mark them with annotations in the source code, where replaceable() is used to mark replaceable components, and system() is used to mark system components. Specifically, the function of Blink is to blink a light-emitting diode periodically, and its replaceable components are two functions, Boot....

The invention discloses a method for deploying a node procedure of a wireless sensing network. The method comprises the following steps of: separating an application procedure into a replaceable component and a system component; changing the calling mode of the system component into jump table indirect calling by the replaceable component; forming a target file by an application procedure source code and a jump table, and chaining the target file to make the target file an executable file; burning the executable file into all the nodes of the wireless sensing network in a way of wired deployment, and restarting all the nodes; executing the application procedure by all the nodes; allowing a user to modify the source code of the replaceable component; relabelling the source code of the replaceable component; adding table items into the pre-compile jump table used in the initial deployment; forming a target file by the source code of the replaceable component and the jump table added with the table items, and chaining the target file to make the target file an executable file; updating the jump table content; modifying a system component call instruction of the replaceable component of the executable file; and transmitting the replaceable component and the jump table into all the nodes of the wireless sensing network in a way of wireless communication, and restarting all the nodes.
Description
technical field [0001] The invention relates to a deployment method of a wireless sensor network node (hereinafter referred to as a node) program, in particular a method for reducing the amount of code transmission, reducing the cost of restarting a node and prolonging the life cycle of network reprogramming. Background technique [0002] Wireless sensor network is a new type of network based on wireless communication that can achieve certain application purposes. It is widely used in environmental monitoring, target positioning and other occasions. The wireless sensor network is composed of a large number of nodes that communicate with each other, and certain application programs are run on the nodes, so that the entire network presents preset application functions. During the long-term operation of the wireless sensor network, the applications running on the nodes may need to be changed due to reasons such as debugging and upgrading. The deployment environment of wireless...
