Embodiment Construction

[0047] The steps included in the data transmission method of the wireless sensor network using the hybrid mobile agent are:

[0048] Step 1). All sensor nodes in the slice exchange information with each other through the simple neighbor HELLO protocol, including identification, location, and energy fields. Each node maintains a neighbor information table for the migration of soft agents and the header node. recommended,

[0049] Step 2). Information is exchanged between slice header nodes. Each slice header node also maintains a neighbor slice header information table, which also includes identification, location, energy and communication overhead.

[0050] Step 3). The user interface node floods the software task agent in all slice head nodes of the network. The agent assigns tasks to all slices in the network through a simple flooding method. The task agent can be changed according to user needs.

[0051] Step 4). The title node receives the task agent, extracts the task de...

Abstract

A data transmission method of wireless sensor network based on multiple mobile agents introduces the mobile agents into the data collection and transmission for network. The main strategies of the method are: 1. collecting local data through self-equipped processing capability of software mobile agents and carrying out local processing; 2. starting hardware agents for continuously carrying out data collection and transmission for a local part of the network during a period with requirement of massive data collection and transmission. Thereby, the traditional mode pattern of distributed user terminal / server of a system is changed, data flow transmitted from a sensor node to a base station (or a gateway) is greatly decreased, the manner of data transmission is simplified and the purpose of energy saving and efficiency is realized. On condition of that once these matters occur in the network, the user needs to obtain accurate and real-time information, a self-navigation mechanism of the hardware agent can get to the occurring area, and the hardware agent can speedily collect and transmit the data cared by the user based on its excellent capability of management and communication.

Description

technical field [0001] The invention relates to a solution for wireless sensor network data collection. It is mainly used to solve the problems of efficient networking and data transmission in wireless sensor networks, and belongs to the cross field of sensor networks and distributed computing. Background technique [0002] With the development of sensors, micro-electromechanical systems and wireless communication technologies, wireless sensor networks have become a new information acquisition and processing technology. It can be applied to areas where wiring and power supply are difficult, areas where people cannot reach (such as areas that are polluted, the environment cannot be destroyed or hostile), and some temporary occasions (such as natural disasters, fixed communication networks are destroyed) and so on. Therefore, the sensor network has very broad application prospects, and has important scientific research value and great practicality in many fields such as milit...
