Experimental evaluation of optimal CSMA
2011 Proceedings IEEE INFOCOM, 2011By ‘optimal CSMA’ we denote a promising approach to maximize throughput-based utility in wireless networks without message passing or synchronization among nodes. Despite the theoretical guarantees on the performance of these protocols, their evaluation in real networking scenarios has been preliminary.

AbstractWe propose an extension of the classical CSMA/CD protocol that eliminates its three main drawbacks. The new protocol, called dual‐mode CSMA/CD (CSMA/DM), operates in two modes, light mode and heavy mode. The light mode of CSMA/DM is almost the same as the original CSMA/CD protocol and is primarily used when the LAN load is light. The heavy mode

Asymptotic performance evaluation of CSMA and CSMA/CD networks
[1992] Proceedings of the 31st IEEE Conference on Decision and Control, 2005Analytical formulas for the performance evaluation of CSMA (carrier-sense multiple access) and CSMA/CD (collision detection) networks with a finite number of buffered users are presented. The asymptotic theory developed by J.-T. Lim and S.M. Meerkov (1987) is extended to local area networks in order to investigate the steady-state performance ...

Extension to the Rude-CSMA Analysis
IEEE Transactions on Communications, 1987This paper extends the rude-CSMA analysis by removing the restriction that each node have the same average arrival rate and average service time. Additionally, some minor errors are corrected.

CSMA/CA through put analysis in hybrid CSMA/CA and TDMA networks
Proceedings of the 2016 International Conference on Intelligent Information Processing, 2016Recently, Wi-Fi has become the mainstream technology to access the Internet. There are many researches applying Time Division Multiple Access (TDMA) to Wi-Fi network in order to provide better performance for different applications. As a result, Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) users are interfered when coexisting with ...

Performance analysis of a stack random access algorithm for CSMA and CSMA/CD channels
IEEE Transactions on Communications, 1992A stack random access algorithm for CSMA (carrier sense multiple access) and CSMA/CO (CSMA with collision detection) channels is presented. The algorithm adapts its operation to the characteristics of the channel at hand by means of two parameters. Utilizing the regenerative character of the induced packet delay process, a lower bound on the algorithm ...

Throughput Analysis for Persistent CSMA Systems
IEEE Transactions on Communications, 1985The channel throughput for a finite number of packet broadcasting users is analyzed for random access protocols, including slotted persistent carrier sense multiple access (CSMA) with and without collision detection and unslotted persistent CSMA with and without collision detection. We consider both p- and 1-persistent CSMA. Our results can be extended

In this paper, we propose a simple theoretical model to compute the maximum spatial reuse feasible in a VANET. We focus on the ad hoc mode of the IEEE 802.11p standard. Our model offers simple and closed formulae on the maximum number of simultaneous transmitters, and on the distribution of the distance between them. It leads to an accurate upper bound

A Matrix Representation of CSMA/CD Networks
IEEE Transactions on Communications, 1985A continuous time Markov chain model of asynchronous nonpersistent CSMA/CD (carrier sense multiple access/collision detection) networks is developed which allows their complete characterization by a matrix whose dimensions are independent of the number of users in the network.

Theoretical Analysis of Slotted ALOHA, CSMA, and CSMA-CD Protocols
1986During the past ten years, the development of random access methods in the packet-switching (broadcasting) multi-user communications environment has been an active research topic [1–11]. A typical system consists of many users trying to send packets to a central station through a common channel.
