Short-range wireless technologies such as IEEE802.11 and Bluetooth enable mobile hosts in broadcast systems to manage cache cooperatively. In nonuniform broadcast systems, hot data are broadcast more frequently than cold data are. Cooperative cache management schemes adaptive to nonuniform broadcast are desirable. In this paper, we first propose a Keep Requesting (KR) extension for existing cooperative cache management schemes, then we propose two novel schemes: Global-Cache-Miss initiated Caching Management (GCM) and Motion-aware Caching Management (MCM). Extensive experiments show that GCM and MCM improve response time, help conserve energy, and adapt to nonuniform broadcast.
