Let BH=(B1H,B2H,...,BdH)be a d-dimensional fractional Brownian motion with Hurst parameter 0H1 and let RH= be the fractional Bessel process.In this paper,we consider the process XH given by XH(t)=dBjH(s)and obtain the local time of XH and Tanaka formula.As a corollary,we get a relationship between the weighted local time of fractional Brownian motion and the local time of the process XH for d=1.
