as per eienstine's relativity moving body increses it's mass when it travel with high speed,at speed of light mass is infinite.photon has mass it is very less,but it has little mass which should be increse when it gets the speed of light.

Because it has no mass at all. It is pure energy.

Photons are massless but because they carry energy they can convey momentum. This allows photons to seem to posess charactistics of particles despite being massless. The momentum of a photon is given by
h / wavelength
where h is Planck's constant

The speed of light is one parameter for the existence of a photon

It does this by being massless.
