Telemedicine means administering medicine over the mobile Internet. This may involve mobile clinics (MC) which, while moving from one geographical location to another to treat patients, always maintain contact with the distant medical centre for backup in the patient treatment process. Usually patients in different geographical locations would have varied illnesses and health profiles. These differences create very different case contents for patientspsila medical records. In the information retrieval context these records are largely multimedia data objects. Over the web an MC is conceptually the client that retrieves data objects from the surrogate server. To attain a reasonable information retrieval or service roundtrip time (RTT) the surrogate would maintain a local cache to contain popular or hot data and thus a high hit ratio. Here we propose to apply the dynamic cache tuning model, namely, MACSC(PE) {Model for Adaptive Cache Size Control with Point-Estimate support}, to achieve hit ratio maintenance for surrogates in the M-SFF (Medical Small Form Factor) medical informatics system. The simulation results indicate that the dynamic cache tuner indeed can aid the success of telemedicine.
