Selfish Behaviours and Counteractions in CSMA/CA Wireless Protocol
ثبت نشده
چکیده
Carrier sensing multiple access with collision avoidance (CSMA/CA) protocol is a medium access control (MAC) protocol used by IEEE 802.11 stations to arbitrate the access of the shared wireless medium. With the increasing programmability of network adapter, malicious users can modify the wireless interface easily in order to gain some unfair shares of bandwidth. In particular, we consider the selfish behaviour of reducing the contention window size in order to get a higher throughput. Three counteractions proposed in [4], [5], [6] were studied and compared. The validity of their problem formulations and solution approaches were commented.

Modelling CSMA/CA protocol for wireless channels that use collaborative codes modulation
A new wireless medium access control scheme is proposed for implementing collaborative codes on the carrier sense multiple access with collision avoidance (CSMA/CA) protocol. To simplify the analysis, a new backoff algorithm is suggested that is simple to implement and to model. Markov chain analysis is used for modelling the proposed CC-CSMA/CA protocol. The resulting model describes the regul...
متن کاملPerformance of Carrier Sense Multiple Access with Collision Avoidance Protocols in Wireless LANs
The performance of Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) protocols, which is adopted as a draft standard in IEEE 802.11, is analyzed in the view of throughput and packet delay. We consider three kinds of CSMA/CA protocols, which include Basic, Stop-and-Wait and 4-Way Handshake CSMA/CA, and introduce a theoretical analysis for them. First, we consider that a network consist...

متن کاملPerformance Analysis of CSMA/CA(Carrier Sense Multiple Access with Collision Avoidance) Protocols for Wireless Local Area Networks in Multipath and Shadowing Environments
The channel throughput and packet delay of wireless media access control (MAC) protocols with Rayleigh fading, shadowing and capture effect are analyzed. We consider CSMA/CA protocols as the wireless MAC protocols, since CSMA/CA protocols are based on the standard for wireless Local Area Networks (LANs) IEEE 802.11. We analyze the channel throughput and packet delay for three types of CSMA/CA p...
متن کاملThwarting Selfish and Malicious Behavior in Wireless Networks
Security is at the core of any communication system and, in particular, of wireless (radio) networks. In this thesis, we focus on three important security aspects in the framework of wireless networks: selfish (noncooperative) behavior at the Medium Access Control (MAC) layer, “radio channel jamming”-based Denial-of-Service (DoS) attacks against sensor networks and secure key agreement in peer-...
