The Wireless Multimedia Sensor Networks (WMSNs) are formed by small devices that are able to capture the multimedia information (video or audio) and to transmit it over wireless channels. The development of wireless technologies, such as: WiFi, Bluetooth, Zigbee, UWB, etc. encourages the emergence of heterogeneous networks

In this project, we focus on the multi-tier architecture to ensure the scalability and the soft-based quality of services. This architecture is composed of three sensor networks with different characteristics as illustrated in figure 1. The first one is a single-tier network formed by homogeneous video sensors which capture the multimedia information. The multimedia contents are relayed to a wireless gateway through a multi-hop path. The gateway is interconnected to a storage hub in charge of the storage of the multimedia content for the subsequent retrieval. The wireless gateway is also connected to a central sink. The second network represents a single-tier clustered architecture of heterogeneous sensors such as: video, audio and scalar sensors that relay data to a central cluster-head which has the capacity to perform intensive multimedia processing.
