The IEEE 802.16 standard is a promising technology for 4G mobile networks. Though supporting versatile service classes, best effort (BE) service class is expected to dominate WiMAX networks, due to operational simplicity. One of bandwidth request mechanisms that subscriber stations (SS) can utilize to issue bandwidth requests (BW-REQ) for BE connections is contention-based random access. An SS starts...
This paper gives an impact analysis of Internet behavior??s activity on the network survivability. The power-law exists in the distribution of network behavior??s activity according to our empirical study. Besides, it is obvious that there is community effect in network communications. Our results overthrow some usual hypothesises as preconditions of trustworthy network study. It??s helpful to assess...
