With the recent advances in Micro Electro Mechanical System (MEMS) technology, low cost and low power consumption wireless micro sensor nodes have become available. However, energy-efficient routing is one of the most important key technologies in wireless sensor networks as sensor nodes are highly energy-constrained. Therefore, many researchers have(More)
Sensor nodes in wireless sensor network are severely energy-constrained. This has been a key factor to limit its performance. So far, many energy-efficient routing protocols have been proposed. Cluster-based routing protocols have been paid much attention because of their advantages. However, the cluster-based routing protocols require information on the(More)
There are many emerging eScience applications. More and more scientists want to collaborate on their investigation with international partners without space limitation by using these applications. Since these applications have to analyze the massive raw data, scientists need to send and receive the data in short time. Most of applications use TCP for data(More)
PURPOSE Traditionally, the surgical repair of umbilical hernia in cirrhotic patients with ascites is avoided because of a significant recurrence rate and perioperative morbidity/mortality. However, recent reports recommend early elective surgery in these patients because surgery-related complications can be reduced with minimally invasive surgery and(More)
