The paper attempts to survey the existing research and development efforts involving the use of mobile agents and intelligent agents for advanced e-commerce solutions. In particular it aims at providing a representative view of the current research trends in developing intelligent and mobile agent-mediated e-commerce including location-aware, mobile and networked comparison-shopping, auction bidding and contract negotiation. A number of selected agent systems are presented with short overviews and then discussed in the context of agent-mediated e-commerce including the scope and specific solutions they address, provided support for agents' migration and users' mobility, and deployment approaches. Finally, a summary of the considered systems is presented together with some concluding remarks including the current state and trends in developing mobile and intelligent agents in advanced agent-mediated e-commerce.
