隨著無線mesh網(wǎng)絡(luò)的普及，其規(guī)模和復(fù)雜程度持續(xù)發(fā)展。然而多跳的mesh網(wǎng)絡(luò)遇到越來越多的難題，比如帶寬降低，無線干擾以及網(wǎng)絡(luò)時延等。譬如，在網(wǎng)絡(luò)中的每一跳吞吐量會下降多達50％，連續(xù)多跳情況下吞吐量下降得更迅速，其結(jié)果將導(dǎo)致網(wǎng)絡(luò)性能的嚴重降低。在語音和視頻應(yīng)用大量運行的極端情況下，時延和RF干擾將達到不可接受的程度，而導(dǎo)致連接完全中斷

Our approach to understanding mobile learning begins by describing a dialectical approach to the development and presentation of a task model using the sociocognitive engineering design method. This analysis synthesises relevant theoretical approaches. We then examine two field studies which feed into the development of the task model.

Purpose of this White Paper This white paper describes a collection of standards, conventions, and guidelines for writing solid Java code. They are based on sound, proven software engineering principles that lead to code that is easy to understand, to maintain, and to enhance. Furthermore, by following these coding standards your productivity as a Java developer should increase remarkably – Experience shows that by taking the time to write high-quality code right from the start you will have a much easier time modifying it during the development process. Finally, following a common set of coding standards leads to greater consistency, making teams of developers significantly more productive.

A system simulation environment in Matlab/Simulink of RFID is constructed in this paper. Special attention is emphasized on the analog/RF circuit.Negative effects are concerned in the system model,such as phase noise of the local oscillator,TX-RX coupling,reflection of the environment, AWGN noise,DC offset,I/Q mismatch,etc.Performance of the whole system can be evaluated by changing the coding method,parameters of building blocks,and operation distance.Finally,some simulation results are presented in this paper.

The LabVIEW Development Guidelines describe many of the issues that arise when developing large applications. The guidelines are based on the advice of LabVIEW developers, and provide a basic survey of software engineering techniques you might find useful when developing your own projects. There is also a discussion of style for creating VIs. Developers who have used LabVIEW and are comfortable in the LabVIEW environment can use the LabVIEW Development Guidelines to maintain a consistent and effective style in their projects.
