This work studies the impact of system algorithms and their parameters, like maximum base station power, power partitioning between overhead and traffic, and connection blocking algorithms. It examines their effect on forward link performance (e.g. capacity, coverage, call blocking and dropout probabilities).

In this paper we analyze the drawback of the traditional SPS technique and propose an efficient shared protection method called M/spl I.bar/SPS. Instead of rejecting an arrival call immediately when a backup lightpath for the optimal primary lightpath cannot be found, M/spl I.bar/SPS continue to try the sub-optimal one until a legal primary-backup pair can be selected. We apply M/spl I.bar/SPS to CERNET/spl I.bar/Like and NSFNET networks. Simulation results show that M/spl I.bar/SPS improves the network performance remarkably.","PeriodicalId":237858,"journal":{"name":"International Conference on Communication Technology Proceedings, 2003.

But besides physical techniques, basic network layer techniques, e.g., the constructions of cellular and the modes of handover, must be broken through in the fourth generation mobile communication systems. The group cell structure proposed in WTI is a novel cellular construction method, which is fit well for these new advanced physical techniques. And slide handover is also novel handover mode emphasized in this paper. According to the current research, the slide handover could improve the system capacity dynamically.","PeriodicalId":237858,"journal":{"name":"International Conference on Communication Technology Proceedings, 2003.

In this paper, we present a new utility function with pricing and propose an economic model using game theory for uplink power control for data services in wireless CDMA networks. Based on the model we propose a synchronous distributed power control algorithm. Numerical simulations are conducted to demonstrate the performance of the algorithm. We investigate the pricing factor on the performance of the system. The results show the performance of convergence of the algorithm is satisfactory.","PeriodicalId":237858,"journal":{"name":"International Conference on Communication Technology Proceedings, 2003.

Compared with TCP, SCTP has two distinct features: multi-homing and multi-stream. Our work investigates the SCTP performance in various network environments, and its availability for different applications. This paper proposes a SCTP multi-homing scheme as the transport layer solution for wireless multi-access networks, using GPRS for retransmission when WLAN connection is interfered, collided or congested. We also evaluate the transport protocol behaviors for e-commerce applications. Through the experiments based on the Linux kernel implementation, we find the SCTP scheme can provide better throughput and more robustness in wireless access networks.","PeriodicalId":237858,"journal":{"name":"International Conference on Communication Technology Proceedings, 2003.

To reduce the redundant data rate (RDR) and improve packet switching rate, a new fixed-size processing method, merge and separate plus SAR (MAS+), in high speed network node is presented. In this new method, the packets larger than the fixed size are segmented.
