A Trust Model for Mobile Service Auctions
With the development of Mobile Commerce and Location Based Services,service auctions between mobile network users have become possible.Trust evaluation is important to select the service for counter parties.The trust model for mobile services auction is reputation-based which will weight the feedbacks by measuring average offset.And comparing to online commodity auctions,trust evaluation rely on Transaction Environment for mobile service auctions,so transaction time,location,money are combined as context factors into trust model,and achieve a dynamic trust mapping mechanism.Simulation results show that,the model can reduce the trust estimation error of malicious node,integrity node,and global node comparing with traditional reputation-based methods,and effectively resist the trust fraud by low-risk transactions.
