A New Backoff Algorithm for the IEEE 802.11 Distributed Coordination Function
White Papers This paper proposes a new backoff algorithm, termed the Linear/Multiplicative Increase and Linear Decrease (LMILD) backoff algorithm, for use with the IEEE 802.11 Distributed Coordination Function. In the IEEE 802.11 Wireless Local Area Networks...

802.11 DCF Denial of Service Vulnerabilities
White Papers This paper addresses Denial of Service vulnerabilities (DOS) in 802.11 wireless LANs that arise from the 802.11 Distributed Coordination Function (DCF). This paper demonstrates that the DCF is vulnerable to equivalent DOS attacks at both the MAC...

Performance Issues With IEEE 802.11 in Ad Hoc Networking
White Papers Although 802.11 was initially designed for infrastructure-based networks, the Distributed Coordination Function (DCF) it provides allows mobiles to access the radio medium without the need of a base station.

A Queueing Model for Finite Load IEEE 802.11 Random Access MAC
White Papers This paper presents an analytic model for evaluating the MAC layer queueing delays at wireless nodes using the Distributed Coordination Function of IEEE 802.11 MAC specifications. The model is valid for finite loads and can account for arbitrary...

Mitigating the Exposed Node Problem in IEEE 802.11 Ad Hoc Networks
White Papers The IEEE 802.11 Distributed Coordination Function (DCF) MAC protocol continues to suffer from the hidden and exposed node problems which characterize CSMA-based protocols. The RTS/CTS exchange partially solves the hidden node problem, but the...

Performance Analysis of the IEEE 802.11 Wireless LAN Standard
White Papers This paper describes the results of the Discrete-Event Simulation of the Distributed Coordination Function (DCF) within the MAC sublayer. IEEE 802.11 is a relatively new standard for communication in a wireless LAN.

How IT drives Ferrari's success
News Driving a race car takes more than good hand-eye coordination and the stomach for G-forces. In the box, the necessary error correction to the data is applied, then the data is decoded and finally the data is distributed to the real-time...
