Description: vhdl source code of fire detection system/fire alarm system especially for high rise building?
This among the requirement :-
according to my "fire detection system for tall building" project by using Spartan 3E FPGA, the vhdl program need to include all of dis specification:-
First of all, we ll put sensor/smoke detector each floor in the tall building.
1) alarm ll activated if the sensor/smoke detector sense a fire
2)at the same time, the actuator will activate in order to control such a elevator and any other machines in the building.
3)the controller will display which floor caught by fire and the sensor/smoke detector initial or current temperature.
4)If there is false alarm, we can stop it by push the reset button .-vhdl source code of fire detection system/fire alarm system especially for high rise building?

Description: 本文是一篇关于传感器网络安全的综述，详细地从各个层介绍了它的研究情况。-Wireless sensor networks(WSNs) use small nodes with constrained capabilities to sense,collect,and disseminate information in many types of applications.As sensor networks
become wide-spread,security issues become a central concern,
especially in mission-criticaltasks.In this paper,we identify
the
threats and vulnerabilities to WSNs and summarize the defense
methods based on the networking protocol layer analys is ?rst.Then we give a holistic overview of security issues.These issues are divided into seven categories:cryptography,keymanage-
ment,attack detections and preventions,securer outing,secure
location security,secure data fusion,and other security
issues.
Along the way we analyze thead vantages and disadvantages of
current secure schemes in each category.Inaddition,we also summarize the techniques and methods used in these categories,and point out the open research issues and directions in each
area.
