Abstract:
Most of the simulators are based on traditional wireless physical capture model,but with the development of hardware,the wireless card gains the capability of selective receiving among several packet in deferent intervals whatever which packet arrive first. Unfortunately there has no related physical capture model been realized on simulators,leaving the gap between theoretical research and hardware reality. This paper tries to solve such problem. Firstly,an interference model based on cumulative signal effect is proposed and an advanced capture model is then built. Upon this capture model a realization on simulator has been given out. The numerical experiment demonstrate that the packet drop rate increased 5.5 times with the node density add up to 3 times. The result shows that the cumulative signal interference has tremendous effect on packet receiving.
