Recent advances in micromanufacturing technology have enabled the development of low-cost, low-power, multifunctional sensor nodes for wireless communication. Diverse sensing applications have also become a reality as a result. These include environmental monitoring, intrusion detection, battlefield surveillance, and so on. In a wireless sensor network (WSN), how to conserve the limited power resources...
In wireless sensor networks energy scarcity is a major concern on energy consumption, and by properly designing on the node network architecture or selecting efficient protocols of the networks, the maximum energy can be reduced significantly thereby increasing the network lifetime. However, in most of the cases, the sensor nodes are either powered by non-replaceable batteries, or there will be a...
The paper employed some independently developed sensors based on the Octopus X platform to build a Zigbee-based Sensor Networks. Also, we implemented a Location-aware living environment by deploying the developed Zigee-based sensor. Besides, through the created window console interface, the sensed data can be transmitted and transformed to the database for further utilized. Moreover, by the devised...
Based on advanced ZigBee and GPRS technology, which collects and transmits data, risk evaluation system of gas pipelines network realize the real time risk analysis and management. This paper introduces the methods of wireless data transmission, gives the architecture of software platform, discusses a processing method for real-time data, and analyzes risk assessment and evaluation model. This has...
