A Scheduling Algorithm with Guaranteed Bandwidth Services for Bluetooth Scatternets

Each Bluetooth device has different traffic loads and bandwidth requirements for various applications. In order to provide time-bounded and QoS-sensitive services with effective performance, this paper proposes a scheduling algorithm adopting a resource reservation scheme that provides bandwidth guarantee to meet various end-to-end bandwidth requirements in scatternets. A coordination scheme is also proposed to efficiently manage guaranteed bandwidth services. In experiments, ns-2 simulator is used to demonstrate the QoS guarantee of the guaranteed bandwidth service.

Bluetree#: An Extendable Bluetooth Scatternet Formation Using Only Slave/Slave Bridges

With the vigorous development of wireless technology, the life style of human beings has been improved with more convenience and comfort. Bluetooth is a critical technology applied in a shorter distance wireless network. The roles of Bluetooth devices can be divided into three types: master, slave, and bridge. However, the master or bridge nodes become the bottleneck of a data traffic flow. A novel Bluetooth scatternet formation is required to obtain better QoS and lower power consumption. This study presents two novel algorithms. The first is Bluetree++ for increasing scatternet performance. The second is Bluetree# for increasing scatternet. The advantages of these two schemes are as follows. (1) A tree structure can be maintained. (2) No master is also a bridge so the load on the master is reduced. (3) The number of links in a bridge is the minimum possible, thus making the overhead in the bridge lighter.

An instant messaging-based multi-agent coordination system

With rapid development of mobile agents, mobile agent coordination becomes an emerging technology in multiagent systems for distributed and Internet applications. In the meantime, instant messaging is getting popular and many people use it to coordinate with each other. This work designs and implements an instant messaging-based multiagent coordination system. Our system has the merits of easy to implement and ubiquitous access. An example of instructor-learner interaction based on our prototype is used to demonstrate the feasibility of our system. A ubiquitous meeting room and an instant messaging mail service are provided in our system for multiagents to coordinate with each other in any place and at any time.

Design and implementation of virtual laboratories using wrapping and agent techniques

This work designs and implements a virtual laboratory that breaks the limits of time and location in traditional education under the innovation of network and information technology. Since the development of a virtual laboratory from scratch is time consuming and costly, our system can be used to wrap an existing CAI tool without knowing its source code. The key concept is to use mobile agents as middleware for wrapping. The framework consists of three parts: mobile agent execution environment, mobile agent, and learning platform. Experimental results demonstrate that the performance of our system outperforms a client-server-based virtual laboratory in terms of dispatching time.
