Sensor nodes in WMSNs should be able to collect various forms of sensing data, prioritize each form of data based on the application service request conditions, and provide a certain degree of Quality of Service (QoS) guarantee. In order for sensor nodes to provide QoS, they must maintain routing information based on delay, reliability, and energy(More)
In Wireless multimedia sensor networks (WMSNs), new metrics are required in order to accurately measure and evaluate link quality of nodes residing along a routing path comprehensively considering end-to-end delay, throughput and radio interference. Moreover, it is important to develop a routing algorithm that can find an optimal path to meet a QoS(More)
Ethernet is one of the most widely-deployed and utilized local-loop networking technology across the world, and IEEE 802.3az working group has confirmed EEE(Energy Efficient Ethernet) standard proposal based on LPI (Low Power Idle) mode. This paper suggests Synchronizing Adaptive LPI Control Mechanism in a bid to improve the energy efficiency between(More)
Smart spaces are dynamic environments for sharing information. People use phones to store and contact personal information and increasingly they have high-speed Internet connections. The smartphone has become a powerful computer in its own hands. In addition, smartphones are now being widely used in interactive broadcast systems. But this makes these(More)
In this paper, we propose the development strategy of message transaction system in electronic business to business system with consideration of security. B2B must be designed to transfer electronic data between business and business in completely secured and reliable form. For the purpose of secured and reliable transaction of electronic data, we propose(More)
