Hybrid Handshake MAC Protocol Based on Priority

Aiming system of mobile phone the inner-flow competition problem, based on the research of IEEE 802.11 DCF protocol mixed handshake provide priority to network coding of continuous forward MAC protocol is proposed, providing access to a higher priority encoding condition data and ensuring the node delay controllable low priority, improve the real-time performance of the system. At the same time with the NS2 network simulation software to mixed into intra flow contention problem based on holding mobile phone system MAC protocol and the traditional competitive flow within the 802.11 MAC protocol simulation, And send the packet success rate and average delay requirement of service to end delay and the average network throughput are analyzed and compared, the intra flow contention problem based on introducing hybrid holding mobile phone system MAC protocol makes the network transmission increases, average end-to-end delay decreases the success rate, Improves network average throughput, optimize the network performance, To provide a guarantee for the real-time performance of the whole network system.
