Abstract
At present, the existing methods of location privacy protection in dynamic peer-to-peer (P2P) network frequently tend to make the cooperative users' locations to be too concentrated and the spatial covering domain to be relatively small.Their ability of anti-center-attack is also quite weak.Aiming at this problem, a method of location privacy protection based on sector region is proposed.An anonymous chain is constructed by the cooperation between mobile stations to forward inquired information and hide the users' real locations as completing accurate inquiries.The direction of anonymous chain is restricted by the sector region, and the stability of the link between the nodes has been taken into consideration while constructing the anonymous chain, so that its spatial covering domain and stability can be ensured.Then, the degree of anonymity and the ability of anti-center-attack can be improved.Experimental result shows that this algorithm performs relatively well in different density of users, whether the anonymity performance or computing consumption.关键词
