Abstract:
Although Machine-to-Machine (M2M) has advantages of high flexibility and the ability of network communication, once the number of devices increases, occurrence of collision would rise, and thus causes efficiency degradation of the Media Access Control (MAC) layer and consumes more power for data for transmission. To resolve the problems M2M device confronts in the WiFi wireless network, this paper modified the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) mechanism of IEEE 802.11 to propose a media access mechanism called CSMA/CA-RBT. CSMA/CA-RBT is an improved media access control mechanism that is compatible with the traditional CSMA/CA mechanism. Using CSMA/CA-RBT, the occurrence of collision can thus be reduced. In addition to improve the performance of CSMA/CA, CSMA/CA-RBT can also add the power–saving improvement mechanism to tackle the power-saving issue. The performance analysis results showed that when the number of mobile nodes increases, the transmission performance and the energy efficiency can be greatly improved using the proposed CSMA/CA-RBT scheme.
