The Internet of Things (IoT) is a novel network archi- tecture that is rapidly gaining attention in the sce- nario of next-generation wireless telecommunications. The basic idea of IoT is perva-
sively providing us with a variety of things or objects, such as radio frequency identification (RFID) tags, sensors, actuators, and mobile phones, which are able to interact and cooperate with each other to realize the tasks of communication, compu- tation, and service [1]. Such a network poses a bright fore- ground for large-data multimedia applications as demand for emerging applications like video on demand (VoD), IPTV, and voice over IP (VoIP) has grown tremendously [2]. Figure 1 provides a classic example of multimedia service architec- ture in the context of IoT.
