Abstract channel This paper analyzes the performance of IEEE 802.11 MAC protocol under a disaster scenario. The performance is measured in terms of the recovery time and the throughput of the protocol when a network disaster occurs. To make the problem amenable to analysis, some approximations are used, and a new technique to collapse a very large state space is introduced. The analytical results are found to agree with simulations. is busy channel is busy idle slots

Considerations and Dynamic Control in Carrier Sense Multiple Access

Abstract — Carrier Sense Multiple Access with Collision Avoidance

by Lukas Kunz, Olav Queseth
"... (CSMA/CA) is probably the most widespread multiple access protocol in use today, mainly due to the tremendous success of the IEEE 802.11 suite of standards. Until now most of the studies done about the protocol have focused on maximizing the performance. However as the bands become more crowded and ..."

Packet Switching in Radio Channels: Part I -- Carrier sense multiple-access modes and their throughput-delay characteristics

by Leonard Kleinrock, Fouad A. Tobagi , 1975
"... Radio communication is considered as a method for providing remote terminal access to computers. Digital byte streams from each terminal are partitioned into packets (blocks) and transmitted in a burst mode over a shared radio channel. When many terminals operate in this fashion, transmissions may c ..."

. An alternate solution is the subject of this paper, namely, nal to sense the presence of other transmissions; this leads to a ground radio packet switching. new method for multiplexing in a packet radio environment: carrier sense multiple access (CSMA). Two protocols are described for CSMA and their throughput

, transmissions may conflict with and destroy each other. A means for controlling this is for the termi-nal to sense the presence of other transmissions; this leads to a new method for multiplexing in a packet radio environment: carrier sense multiple access (CSMA). Two protocols are described for CSMA

Overlapped carrier-sense multiple access (OCSMA) in wireless ad hoc networks

by Madhan Sivakumar, John M. Shea - IEEE Trans. Mobile Computing , 2009
"... Abstract — In wireless ad hoc networks with multi-hop routing, a node A may know the contents of a packet being transmitted by a neighbor B because A may have transmitted the packet to B in a previous interval. In networks not employing spreadspectrum multiple access (SSMA), a transmission by B will ..."

CSMA/SF: Carrier Sense Multiple Access with Shortest First

by Guanhua Wang, Student Member, Kaishun Wu, Lionel M. Ni
"... Abstract—Energy efficiency is the main concern in wireless sensor networks (WSNs) due to devices ’ limited battery power. Because the heavy burden of nodes that near the sink, this “energy hole problem ” makes nodes near the sink have faster energy depletion than others. Because of this, the lifetim ..."

, the lifetime of WSNs, to some extent, is determined by the power consumption of communication between sink and sensing nodes that near the sink. To address this issue, we propose CSMA/SF (Shortest First) protocol to reduce power consumption of sink-node com-munication by minimizing energy cost in carrier sense
