The existing controlled UDP schemes for personal terminal to personal terminal (P2P) at application layer are invalid for the congestions in transport layer since the controlled UDP traffics still block the TCP flows. Thus, it is difficult to achieve the congestion control for the TCP/UDP hybrid traffics network. To solve these problems, C-UDP protocol and new edge router are proposed for hybrid traffics'...
This paper provides parameter setting and 2-D local stability conditions for TCP/RED networks. In general, a network cannot avoid congestions due to the limit of network capacity. The RED scheme is one of the representative AQM that was proposed to avoid and alleviate network congestions. However, the issue of network stability with many TCP subscribers needs to be considered when setting the RED...
The existing RED algorithms act on subscribers and edge routers only, and the link capacities between edge routers and connected core routers have not been considered. When core router in a two layers' network experiences congestion, the connected edge routers have no ability to response their access data rates. Thus, it is difficult to achieve the congestion control for the large scale network with...
The location information of sensor nodes is needed for location-based services and network management in wireless sensor networks. Among the many kinds of localization schemes researched to find the location of sensor nodes, a few some schemes presume the use of mobile beacons because using mobile beacons has many potentialities. In particular, a localization scheme with mobile beacons, such as proposed...
