These technologies can be used to develop wireless network directly. Recently, there are many communication systems brought up in order to offer mobile users with the best services. The combination of wired network and wireless network could be used to access data mutually. In this paper, the multi-tier architecture is based on IP network. Combining all these systems in a multi-tier IP-based wireless network is an important issue. In this paper, we propose a novel handoff algorithm of wireless communication for multi-tier IP-based network; the handoff algorithm is divided into two parts, which are Old-tier priority and New-tier priority algorithm. Making programs by C for simulating, and making sure that the algorithm is workable. The results of simulation show 11.99% of handoff frequency has been decreased and 8% of using rates of resource has been increased.","PeriodicalId":382765,"journal":{"name":"17th International Conference on Advanced Information Networking and Applications, 2003.

According to DSARP, the reliable route for delay sensitive traffic can be supplied and the route can be selected based on the constrained condition - \"the shortest route and the lowest average delay\". Therefore, the \"hotspot\" on the shortest path can be avoided. Meanwhile, DSARP can provide a QoS guarantee and improve the performance of the network. Simulation results show that DSARP performs better than the DSR routing protocol used in ad hoc wireless networks.","PeriodicalId":382765,"journal":{"name":"17th International Conference on Advanced Information Networking and Applications, 2003.

However, the entire bandwidth increases because of an increase in the transmission capacity of one wavelength. Therefore, the connection setting delay time should be considered because the data transmission time is shortened relatively. In this paper we propose a new connection setting method considering connection setting delay. The performance evaluation via simulations shows that the proposed method has better performance than the conventional forward and backward reservation methods.","PeriodicalId":382765,"journal":{"name":"17th International Conference on Advanced Information Networking and Applications, 2003.

The AR Clipboard is a computer-generated information clipboard that allows a user to keep virtual objects on it on a video see-through head mounted display (HMD). The twist-information presentation method provides a user with wide view of a HMD by presenting a virtual object in the peripheral space of a user's view, which is generated by the angle difference between the user's head and body. Using AR Clipboards, a user can carry virtual objects on them around his/her body and can look at one of them as long as the user turns his/her face toward a clipboard. Moreover, a user can grasp a virtual object and post it on one of the clipboards by performing hand postures.","PeriodicalId":382765,"journal":{"name":"17th International Conference on Advanced Information Networking and Applications, 2003.

Particularly, mobile applications for decision support systems, such as mobile data warehouses, are very attractive. However, mobile application imposes new requirements such as disconnection from the data sources. These requirements force the use of incremental update algorithms in order to update the mobile hosts. We extend the idea of incremental update algorithms with an optimized hierarchy of views which enables improving performance on mobile data warehouses. Moreover, we prove that other aggregate functions apart from the standard ones, in particular, standard deviation, variance, and ratiotoreport, are suitable for being used in incremental update algorithms.","PeriodicalId":382765,"journal":{"name":"17th International Conference on Advanced Information Networking and Applications, 2003.

The experimental results show that the method gives quite an impressive performance. Since the values of most adjacent pixels in an image are closed, we can use this simple, effective way to compress the image.","PeriodicalId":382765,"journal":{"name":"17th International Conference on Advanced Information Networking and Applications, 2003.

This paper investigates concatenated coding as a means of improving and optimizing the data link performance. Taking the burst error characteristic of satellite links and ATM cell format into account, several coding schemes are evaluated by simulations. A concatenated coding scheme is therefore presented that can not only get fibre-like performance but also has the ability to correct long burst errors. The new scheme concatenates an outer RS code and an inner convolutional code, and can be implemented at a low complexity. Experiments show that it is practical and applicable for onboard applications.","PeriodicalId":382765,"journal":{"name":"17th International Conference on Advanced Information Networking and Applications, 2003.
