QoS-centric collision window shaping for CSMA-CA MAC protocol

, 2010
Collision Sense Multiple Access (CSMA) has been preferred to Time Division Multiple Access (TDMA) as medium access scheme for Wireless Multimedia Sensor Network (WMSN) in the scenarios where the traffic is bursty in nature and multiple consecutive and ...

Performance analysis of distributed cluster-based MAC protocol for multiuser MIMO wireless networks

EURASIP Journal on Wireless Communications and Networking, 2011
It is known that multiuser multiple-input multiple-output (MIMO) communication can enhance the performance of wireless networks. It can substantially increase the spectral efficiency of wireless networks by utilising multiuser interference rather than ...

Load-regulated CSMA

, 2009
In this paper, we derive throughput of a threshold-based transmission policy, namely Load-regulated CSMA, taking into account the propagation delay of the medium and the offered load at different probability of the fading channel.

Performance Evaluation of CSMA/CA on CC2530

, 2016
[[abstract]]在無線網路普及的現代，封包傳送效率日趨重要，碰撞的發生與傳送效率極為相關。在無線網路避免碰撞的機制中，IEEE 802.11 DCF協定與IEEE 802.15.4 CSMA/CA協定是最廣為人知的。他們主要的不同一是監聽通道狀態的方式與次數。在DCF協定中，節點不斷的偵測通道狀態，對通道狀態可以立即性的處理；在IEEE 802.15.4 CSMA/CA協定下，節點只會在backoff結束後偵測通道一次，期間若通道已被佔用是無法得知的。此篇論文主要是於IEEE 802.15 ...

A Carrier Sense Multiple Access Protocol with

, 2008
— In this paper we propose an alternate approach to collision resolution in a CSMA protocol. Most contention protocols resolve collisions by backing off in time.

Performance of ALOHA and CSMA in spatially distributed wireless networks

, 2008
—In this paper the performance of unslotted ALOHA and CSMA are analyzed in spatially distributed wireless net-works. Users/packets arrive randomly in space and time accord-ing to a Poisson process, and are thereby transmitted to their intended ...

P-CSMA: A Priority-Based CSMA Protocol for Multi-Hop Linear Wireless Networks

, 2013
In this paper we consider a multi-hop wireless network, where a source transmits data to a destination node, through a route composed of multiple relays which are randomly distributed over a line.
