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)
As network equipment consumes much more energy than ever before, research effort has been focusing on developing the access network protocol that aims to achieve communication with maximum energy efficiency. Ethernet is the most widely deployed access network protocol around the world. To improve energy efficiency in Ethernet protocol, IEEE 802.3az working(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)
