The IP Multimedia Subsystem (IMS) aims to provide cellular access to all the services that the Internet offers; it is an overlay control layer on top of an IP layer. Wireless Sensor Networks (WSN) with mobile sinks is useful in a wide range of scenarios since they can improve the overall network lifetime and increase data capacity. Combining the capabilities of IMS with the rich set of contextual information captured by mobile sink WSNs will open the door to a wide range of novel multimedia services. This paper proposes an overlay architecture for the integration of IMS with mobile sink-based WSN.
