Performance analysis of Slotted CSMA/CA MAC protocol under different parameters for static IEEE 802.15.4 Wireless Sensor Networks

Performance analysis of Slotted CSMA/CA MAC protocol under different parameters for static IEEE 802.15.4 Wireless Sensor Networks Amol Patel and Raksha Upadhyay Institute of Engineering and Technology Devi Ahilya Vishwavidyalaya Indore (M.P.), India _______________________________________________________________________________________ AbstractWSNs have emerged as an important area for research and development because of its application in monitoring and tracking. This paper, presents and discuss the performance of slotted CSMA/CA MAC protocol for static WSNs, with only minor add-ons to the protocol by tuning its parameter adequately. The performance of the slotted CSMA/CA MAC protocol is evaluated and analyzed for different network configurations to understand the impact of the protocol parameters such as super frame order, beacon order, back off exponent, frame size and CSMA/CA overheads on the network performance, namely in terms of throughput, average delay and energy consumed by the network. The proposed work is implemented on Qualnet 5.0.2 Network Simulator and the performance of CSMA/CA MAC protocol is evaluated for static WSNs.
