Protecting sensitive information systems from security threats such as unauthorized access, information eavesdropping and information interfering, is significant. Most of the natural approaches employ strong authentication or cryptography systems to protect critical data. But those approaches do not stress on the potential amount of risks associated with sensitive information, especially the vulnerability...
Enhanced Multimedia Broadcast/Multicast Service (EMBMS) is a new function defined in 3GPP specification, which supports download delivery and streaming delivery to group users in LTE mobile networks. In 3GPP Release 8 specification, the EMBMS transmission is classified into single-cell transmission and MBSFN (Multicast Broadcast Single Frequency Network transmission). In MBSFN, the statistical multiplexing...
In this paper, we propose a MAC layer multicast protocol for 802.11n WLAN for the first time. In IEEE 802.11n, new feature at MAC layer, such as frame aggregation and more flexible link adaptation are defined to increase the effective throughput. Recently, several multicast protocols at MAC layer have been proposed for WLAN. However, these protocols don't consider the new features defined in 802.11n,...
