Network selection is a key problem when a user faces multiple available wireless networks. Especially, this problem becomes more complicated when multiple users share multiple wireless networks due to the interaction and competition among users. Most existing works on this multiple networks sharing problem assume that users have the same utility functions, which neglect the fact that users may have...
The massive random accesses of machine type communication (MTC) in current wireless networks (e.g. LTE-A, WiMAX) are a challenging and urgent issue. In this paper, the random access performances in LTE-A networks are first analyzed in terms of success probability, access delay, physical random access channel efficiency, and the number of retransmissions. Based on the analysis, two QoS-based optimization...
This paper discusses the optimization and implementation of a new internet resource locating technology-Handle protocol and server. It introduces the basics of Handle protocol and the characteristics of Handle system. Then it focuses on the overall architecture, especially, the design of the Authority Cache and the Dynamic Thread Pool. The innovation of the paper is the proposal of a high performance...
