2004 Proceedings of the 2004 ACM workshop on Wireless security - WiSe '04  
Our characterization reveals rich information about the PHY/MAC layers of the IEEE 802.11 protocol such as the typical traffic mix of different frame types, their temporal characteristics and correlation  ...  Moreover, we identify various anomalies in protocol and security of the IEEE 802.11 MAC. Regarding the security, we identify malicious usages of WLAN, such as email worm and network scanning.  ...  We also want to thank Nikhil Purushe for the helps in SNR measurement in Section 3.4.

2007 Proceedings of the 2007 ACM CoNEXT conference on - CoNEXT '07  
So, capture-awareness needs to be incorporated into MAC protocols to enable concurrent communications where feasible.  ...  Our idea is somewhat similar to the one proposed for enterprise WLANs in [4] but is designed to extract benefits from capture-awareness.

On the performance of Redundant Traffic Elimination in WLANs

Emir Halepovic, Majid Ghaderi, Carey Williamson
2012 2012 IEEE International Conference on Communications (ICC)  
However, frame retransmissions generate additional traffic at MAC layer, which reduces the effectiveness of RTE in general case.  ...  We find that including parts of MAC headers in RTE can increase overall bandwidth savings by up to 53% in a public WLAN.  ...  We start by considering MAC-layer RTE savings for WLAN, as opposed to only IP-layer savings considered in previous works.  ...

REVAMPING QUALITY OF SERVICE OF VIDEO STREAMING OVER WIRELESS LAN

Rohan Thakkar .
2014 International Journal of Research in Engineering and Technology  
Depending on their applications, the solutions have focused mainly on the following three network layers: Media Access Control layer (MAC), Application layer (APP) and Physical layer (PHY).  ...  For the sake of adaptive QoS, the cross-layer architecture assumes that layer information could be exchanged between application layer and lower layers.  ...  We would also like to thank him for guiding us in the implementation of the prototype.  ...

A Cross-Layer Interworking of DVB-T and WLAN for Mobile IPTV Service Delivery

Ismail Djama, Toufik Ahmed
2007 IEEE transactions on broadcasting  
We propose a seamless cross-layer inter-working between broadcasting network (i.e. DVB-T) and 802.11 WLAN network for adaptive and interactive mobile TV service delivery.  ...  The 802.11 WLAN is considered today as the "de-facto" wireless access network for the last miles connection.  ...  The 802.11 standards cover both the Physical Layer and the Medium Access Control (MAC) layer. They were conceived for the best effort traffic.  ...

2014 arXiv   pre-print
Comprehensive in-depth comparative analysis of each of the security mechanisms is driven by review of related work in WLAN security solutions.  ...  Securing wireless networks can be difficult because these networks consist of radio transmitters and receivers, and anybody can listen, capture data and attempt to compromise it.  ...  They equally lack capacity to handle attacks on physical layer since they provide security on layer two and above.  ...
