Embodiment Construction
[0017] The specific implementation process is as image 3 , with the following characteristics:
[0018] The whole wireless sensor network includes sensor nodes, working nodes, super nodes, application codes and trust data.
[0019] The specific implementation of the present invention includes an application code request stage, an application code transmission stage and an application code execution stage.
[0020] Application code request phase;
[0021] First, two new functional entities are deployed in the wireless sensor network: super node and worker node. Users can upload new application codes to super nodes through the traditional network. If a worker node needs to refactor the application, it will send a code request message to the supernode.
[0022] Application code transfer phase:
[0023] After receiving the message, the supernode obtains the code image from the code library through the code management module, processes it and migrates it to the working node t...

The invention relates to a method for deploying application codes based on trust in a wireless sensor network. The basic idea is that two new functional entities, which are a super node and a work node, are defined in the wireless sensor network at first. Users can upload new application codes to the super node through a traditional network. The work node sends a code request message to the super node if the work node requires reconstructing applications. Codes on the super node are transferred to the work node through multi-hop communication after the super node receives the message, and an integrated trust technology selects nodes with a high trust degree to carry out code transmission in the code transmission process. Finally, the work node reconstructs the local applications through executing the new application codes. The method for deploying the application codes based on trust can meet ever-growing application requirements of the users, transmits the application codes to the target nodes which need to carry out application reconstruction efficiently and reliably, and eliminates malicious nodes out of code transmission. Meanwhile, the method provided by the invention greatly reduces energy consumption of the nodes in the network, and belongs to the field of computer networks.
Description
technical field [0001] The invention relates to a trust-based application code deployment method in a wireless sensor network. The basic idea is: firstly, two new functional entities are defined in the wireless sensor network: a super node and a working node. In a sensor network with a cluster structure, the cluster head node is generally used as a super node. A working node can be either a cluster head node or a member node. Users can upload new application codes to super nodes through the traditional network. If a worker node needs to refactor the application, it will send a code request message to the supernode. After receiving the message, the code on the super node is migrated to the working node through multi-hop communication, and the node with high trust degree is selected for code transmission in the process of code transmission. Finally, the working node reconstructs the local application by executing the new application code issued by the super node. The trust-b...
