Performance Analysis of CSMA/CA in Wireless Local Area Network

With the rapid advance of mobile computing, high speed Wireless Local Area Networks (LAN) attracts a lot of research interests in recent years. A new international stander IEEE 802. 11 on wireless LAN has been established. Its physical transmission is realized by either spread spectrum communication or non-directive infrared. The medium access control of IEEE 802. 11 is using carrier sense mult...

Performance analysis of CSMA in an unslotted cognitive radio network with licensed channels and unlicensed channels

We consider a carrier sense multiple access(CSMA) in an unslotted cognitive radio network under a mixed spectrum environment of licensed channels and unlicensed channels. In this system, primary users use only licensed channels, while secondary users use unlicensed channels and opportunistically can use licensed channels unused by primary users temporally. If an arriving secondary user(SU) does...

Analysis of a CSMA-Based Wireless Network with Heterogeneous Nodes: Feasible Throughput Region and Power Consumption

We analytically study a CSMA-based network with heterogeneous nodes in this paper. In the network, each nodes has its own throughput demand to a common base station and the MAC protocol considered is a virtual CSMA by the RTS/CTS handshake mechanism. Each node individually chooses its probability of sending a RTS packet, and the probability vector of all nodes will determine the average through...

Performance analysis of unslotted CSMA/CA in wireless networks

In this paper a novel analytical model for the saturation throughput of unslotted Carrier Sensing Multiple Access with Collision Avoidance (CSMA/CA) in wireless networks is proposed. A fixed point procedure is developed based on the interaction of the Physical layer (PHY) and the Medium Access Control sublayer (MAC). The output of the Clear Channel Assessment (CCA), i.e. idle or busy medium in ...
