Performance Analysis Of Protocol In Wireless Sensor Network With C-CC Access Control Mode

The research of Contention-Collision Cancellation (C-CC) access control mode has made great progress, but this is reflected in the theoretical aspects. Along with the rapid development of computer technology, microelectronics, integrated technology and communication technology, wireless personal area network and wireless sensor networks has attracted more and more attention of researchers. IEEE802.15.4has been seen as a wireless sensor network communication standard so IEEE802.15.4has also attracted more and more attention.As a low-rate, low-power communication standard, IEEE802.15.4developed a network communication standard on PHY layer and MAC layer. CSMA/CA mechanism is the core content in IEEE802.15.4Mac layer, but many parameters in this mechanism have not been given a value determined, only gives a certain range. This provide us a portal to study IEEE802.15.4.This article aims to use C-CC access control mode in the IEEE802.15.4standard MAC protocol CSMA/CA mechanism.First, we used NS2simulation platform to complete a lot of simulation about IEEE802.15.4. And by analyzing the trace file, we can obtain the impact of BO CW and acknowledgment frame mechanism on network throughput delay and energy consumption.Then take into account that C-CC access control mode and IEEE802.15.4standard all support star topology and they also have a lot of similarities. By changing some of the parameters and processes, we can combine the two modes.At last, through the simulation of the new mac, we can see that after the fusion the network throughput is reduced, the delay and the packet loss rate is increased, but the energy consumption is greatly reduced. As we all know low-power is the core issues in the IEEE802.15.4, so we can use C-CC access control mode and IEEE802.15.4to make a new protocol.
