Abstract

This paper proposes a simple Wireless Sensor Network (WSN)-based air quality monitoring and fining system for industrial and urban areas. The proposed framework comprises a set of sensors which senses gas (CO), pressure, humidity and temperature that are deployed on stacks and infrastructure of a ZIGBEE WSN and a central server to support both short-term real-time incident management and a long-term strategic planning. The parameters are continuously sensed from the sensor and the penalty will be issued based on their level above threshold value. This architecture would use open-hardware open-software gas sensing capable motes made by Libelium. These motes use the ZIGBEE communication protocol and provide a real-time low cost monitoring system through the use of low cost, low data rate, and low power wireless communication technology. The proposed monitoring system can be transferred to or shared by other applications. We also introduce a simple but efficient clustering protocol dubbed hereafter "Clustering Protocol for Air Sensor network" for the proposed WSN-AQMS framework. CPAS proves to be efficient in terms of network energy consumption, network lifetime, and the rate at which data is communicated.

Abstract

This paper present a technology independent design and simulation of a modified architecture of the carry save order it require a minimum of logic gates binary addition is carried out by series of XOR, AND and shift left operations. These operations are terminated with a computer signal indicating that the result of addition is obtained. because the number of shift operation carried out and varies from 0 to n for n bit addends the method was developed in all the possible addends of 2 to 15 bits the mathematical model was detected and used to predict the number of shifts required for binary numbers such as 32.68 or 128 bits it is used in both synchronous and asynchronous modes of operation.
