Multimedia sensor networks design for smart home surveillance

Hardware and software design of multimedia sensor networks are proposed for smart home surveillance system, which employs multiple sensing and distributed processing and event-triggered surveillance. This network consists of the following two tiers: the wireless sensor network (WSN) tier is established on the IEEE 802.15.4/ZigBee protocol, constituting of scalar sensor nodes capable of capturing and processing scalar data and transmitting it to a sink node; the video surveillance network tier constitutes of multimedia sensor nodes connected by Ethernet, which can transmit multimedia content, such as compressed video and audio streams and the monitor data from the WSN tier, to the monitor center or user. Base on the designed multimedia sensor networks, the surveillance system can provide the user with harmful events alarms, event-triggered or continuous remote surveillance of his/her home.
