wireless communication

Because of the obvious advantage in short-range wireless communication, ultra wide-band (UWB) systems have drawn great attention. Since UWB signals use extremely broad bandwidth for transmission by sharing the same frequency spectrum with other existing systems, interference with other systems is caused, which become the bottleneck of the UWB technique development. In this paper, based on compressed Chirp pulses and Hermite orthogonalization process, a novel method to generate UWB pulses is proposed. Selecting significant TD-SCDMA as the co-existing system, the principle, application and effect of the new pulse shaping method in the interference mitigation between UWB with TD-SCDMA system are discussed in detail.This paper is made up of the following parts:First, the definition, character and application of UWB technique are overviewed. A variety of interference mitigation solutions for UWB and other systems are introduced. The advantages and shortcomings of the traditional pulses in UWB systems application are pointed out.

New Wireless Sensor Network Node with the Multi-sensor Module

In this thesis, we firstly introduce the architecture, characteristics and applications of WSNs, and point out the state-of-art of WSNs and sensor node. Then, modular scheme of sensor node is proposed, following the explicit scheme of interface module processor, wireless communication, sensor and power supply. In hardware design, the comparison among various types of devices, the design of circuit and electric rules are discussed in detail. In addition, this article also designs a software framework of sensor node, and proposes the detailed process of the multi-sensor module, interface, processor, the SPI interface of the communication module for node and the adaptive application of data processing. The whole software framework makes the functional design of the node module realized.Subsequently, we evaluate the performance and functionality of the new multi-sensor node based on an experimental testbed. Finally, we summarize the work and make an outlook in the future.

technologies

Wireless sensor networks (WSNs), incorporating many technologies such as sensor, micro-electro-mechanical systems (MEMS), wireless communication and network, could cooperatively collect the environmental information, and realize the integration of the physical world and communication network. How much do these cheap straighteners cost?Thus WSNs are becoming one of the research hot spots that receive much attention from governments, enterprises and institutes. Everyone wants to get cheap Lacoste Shirts .How to design a new high-performance sensor node is a key problem to improve the performance of the network and expand its scope of application.As we know, the existing sensor nodes have many obvious disadvantages such as single functionality, poor scalability for sensor module, complexity for secondary development, so it is necessary to design and implement a new type sensor node, modular and reconfigurable.Polo shirts are yours now! Based on the original low-cost, low-power sensor node in our group, this thesis realizes the modular design of sensor node for processor, RF circuits, power supply and proposes a general module supporting various sensors to ensure the flexibility and reduce the complexity to promote the marketing for a wide range of applications in the future.

research topics

Multipath routing in WSNs has gradually become one of the hot research topics. At the same time, there will be ineffective domains of empty of energy, congestion, and disaster in WSNs. In this dissertation, we firstly design a multi-path routing protocol based on effective domain in WSNs.We firstly study the current single path routing protocols of WSNs, AODV, MSRP, and multi-path routing protocols, analyze the factors and characteristics of current routing protocols considering. And then we propose a multi-path routing protocol based on valid domain,describe the routing scheme, message format and programming flow chart in details.At the same time,we propose a mechanism named "neighbor node table interaction mechanism"in braid nodes.Then we give a way to insulate invalid domain.Subsequently, we implement the protocol in micro sensor node MSR6680, which is a platform designed by ourself. Then, we analyse the performance by executing a series of comparisons with other similar protocols. The test results show that our mechanism performs better in stability, reducing the nonuniformity of energy consumption, and based on valid domain. We close this paper by summarizing our works and proposing future works.

Project Description

Build up a MES/SFCS system for Acer's OEM partner just like acer's assembly factory lines,whose name is ChenduLacoste Polo Shirts Jiannanchun,yes,it's just the famous wine provider in China as you known.at the same time ,this project will be acting as a formism project to support the West-China Area for acer Incorporated.and the MES system is just like acer-self assembly workshop,so,there few functions need to update and only configurateed some environment parameters to run up.but all system processes we need to simulate a time before translating to Jiannanchun factory,that's include H/D &S/W environment,execrutable programs,DB schema,Data,routing flow designs and ectMigarating the mes/sfcs system to Acer Incorporated company's OEM partner named Lianyi Jingmi Limited,who will be acting as the assembly lines outside the acer factory,for the acer's capacity is not enough to satisfy the big customers like HP,NEC,HITACHI ect.So the mes/sfcs system must run at 7*24*365 level, and the collected assembly Cheap Lacoste Polo Shirts data need to transfer to acer's mes/sfcs system database and become the acer factory lines' capacity to supply the customer's shipping requirement.therefor the stability and realtime features are far more seriousBe a MES/SFCS leader of acer Incorporated,I acted the project manager to implement the mes/sfcs system to partner,from setup the local ares network(ethenet),mes/sfcs system runtime environment just like setup DBMS,server,clients,system station ,data transfering mechanisim to acer,user training,documents migaration ect,those all due to me planned and executed,at that time, there are 5 helpers and cost 3 weeks to completed this migaration project successfully.
