Problems solved by technology

The C / S mode is a direct connection mode between the client and the server, which requires a dedicated client and human intervention. The distribution function is weak and cannot quickly reflect the latest information of the data source; Only when the server is connected to the network can the B / S terminal be used, which cannot meet the needs of transparent services anytime and anywhere in the pervasive computing environment

Embodiment Construction

[0046] For convenience of description, assume the following data processing application.

[0047] Construct a ubiquitous computing environment that is laid out by a wireless sensor network and divides the area into uniform grid cells.

[0048] The data processing method using the mobile agent-based data transmission and processing control scheme is as follows:

[0049] Step 1: Initially, each node in the wireless sensor network has the same energy E 1 , in each grid unit, each node estimates the total communication energy consumption E of a data transmission when it acts as a cluster head node 2 , that is, each cluster head node needs to receive a notification of preparing to transmit information from the base station, and then forward it to the child nodes once (there are C child nodes). At this time, the child node with the farthest distance from it receives the information The farthest distance is d); the reverse process is to collect the information of all child nodes fo...

Abstract

The invention relates to a pervasive computing environmental data processing control method based on mobile agent. A pervasive computing environment network structure is divided into three sections: a base station, grids and clusters. Data collection, data transmission and data processing are executed in the data processing process, and each section is achieved by using the mobile agent technique. The communication between each two section is achieved by message communication between mobile agents. The key section is data transmission. The network region in the pervasive computing environment is divided into uniform grids, the clusters are constructed in each unit grid, and a shortest path tree is constructed based on the root of a cluster header node in the cluster to form a tree-shape cluster structure. Data processing mobile agents are allocated to cluster headers through the base station, and finally data collection, transmission and processing are executed by the mobile agents, thereby balancing the network energy consumption, lowering the network data transmission energy, reducing the network data processing pressure, and improving the data processing speed.

Description

technical field [0001] The invention is a mobile agent-based data processing control scheme. It is mainly used to solve the data transmission and processing problems in the pervasive computing environment. Based on the mobile agent technology, the clustering method is used to solve the data processing problems in the pervasive computing environment, which belongs to the application field of distributed computing and pervasive computing technology. Background technique [0002] The ubiquitous computing model embeds devices into various environments of people's lives, making communication services and other human-centered computing and information access services possible at any time and any place, and many computing devices pass through the world. The Internet provides users with more personalized services. The ubiquitous computing environment has the characteristics of mobility, limited equipment energy, narrow network communication bandwidth, and autonomous services. [0...
