第40届世界标准日祝词2009年10月14日标准应对气候变化

The world is facing a critical challenge.Increasing greenhouse gas emissions are raising the earth's average temperature.As a result,dramatic climate change is forecast and global scientific opinion predicts enormous developmental,economic,social and environmental stresses on our planet.     

Load balancing routing with queue overflow prediction for WSNs

The ease of deployment of Wireless Sensor Networks (WSNs) makes them very popular and useful for data collection applications. Nodes often use multihop communication to transmit data to a collector node. The next hop selection in order to reach the final destination is done following a routing policy based on a routing metric. The routing metric value is exchanged via control messages. Control messages transmission frequency can reduce the network bandwidth and affect data transmission. Some approaches like trickle algorithm have been proposed to optimize the network control messages transmission. In this paper, we propose a collaborative load balancing algorithm (CoLBA) with a prediction approach to reduce network overhead. CoLBA is a queuing delay based routing protocol that avoids packet queue overflow and uses a prediction approach to optimize control messages transmission. Simulation results on Cooja simulator show that CoLBA outperforms other existing protocols in terms of delivery ratio and queue overflow while maintaining a similar end-to-end delay.

     

World Standards Day Message 14 October 2010 Standards make the world accessible for all

At least 650 million people globally are affected by some kind of disability;one quarter of all citizens in developed countries are 60 or older and,by 2050, most developing countries will have caught up.     

Implementation and performance evaluation of IEEE 802.15.4 unslotted CSMA/CA protocol on Contiki OS

In the wireless sensor networks domain, one of the most used standards is IEEE 802.15.4. This standard has been made available on many low power operating systems such as TinyOS and Contiki OS. It is crucial for the implementation to be compliant with the specifications of the standard. In the case of Contiki OS, the provided version of the main medium access algorithm, unslotted Carrier Sensing Multiple Access with Collision Avoidance (CSMA/CA), presents many flaws. In this paper, we discuss the implementation of the provided CSMA/CA algorithm and we point out to the parts that do not respect the standard specifications. We also propose and implement a compliant version of this algorithm and show through simulation the correctness of the implementation.     

第39届世界标准日祝词—标准与智能绿色建筑

10月14日是世界标准日。今年，国际标准化组织（ISO）、国际电工委员会（IEC）和国际电信联盟（ITU）联合发出世界标准日祝词，主题是“标准与智能绿色建筑（Intelligent and sustainable buildings）”，旨在通过标准的实施和推广，将绿色理念与信息通讯技术融入建筑之中，减少污染和能耗，为人类提供更加安全舒适的生活空间。     

World Standards Day Message 14 October 2007 Standards and the Citizen: Contributing to Society

The Global Village brings a broad range of rights and obligations to its citizens. These include rights to safety, security,health and access to information. Obligations include protecting the environment and respecting the safety, property and privacy of others. Standards help citizens to exercise these rights and obligations. They do this, for example, by providing consumers with information and protection, by ensuring the quality and safety of products and services, by defining requirements or giving guidance related to the environment and other issues important to citizens including societal equity, health, security, information and communication, and fair trade.
