On wireless grids users and resource providers are not only mobile, but also nomadic. Information services on wireless grids have special requirements. Resource information has to be updated when users and resource providers arrive and depart frequently. Meanwhile, information services are also mobile, so the clients and information sources should dynamically detect the existence and departure of information services. Information services on wireless girds may be not as powerful as those on wired grids, so information services are required to be decentralized and light-weighted. In this paper we present a WSRF-compliant and P2P based information service architecture to meet the special requirements on wireless grids, and implement the architecture on Globus 4. We extend the function of MDS4 to support wireless grid resource discovery, query and monitoring. P2P mechanism is employed to integrate information services to provide grid-wide resource information. The clients and information sources dynamically probe nearest information services to query or register resource information. Some implementation issues are discussed as well.
