S-MAC protocol with service differentiation
Qianbin Chen · Journal of Chongqing University of Posts and Telecommunications · 2008
As S-MAC protocol doesnt consider QoS,this paper introduces an S-MAC protocol with service differentiation,which gives the benefit that different priority nodes gain different chance of access channel.This method can advance QoS performance of sensor network.Simulation result shows that the improved S-MAC protocol increases QoS performance of network.
