A Multi-QoS Constraint Routing Protocol for Multimedia Wireless Sensor Networks
Source: Northeastern University
Image and video sensing data in the Multimedia Wireless Sensor Networks make many requirements in the resource of bandwidth and energy. For the purpose of real-time transmission of multimedia data, this paper proposes a new QoS protocol applied to Multimedia Wireless Sensor Networks - REAR. In this protocol metadata is used to establish multi-path routing for reduce the energy consumption and a cost function is constructed to evaluate the consumption of the transmission links which trades off the relationship of energy and delay to chooses a QoS routing. The experiments show that the protocol could ensure the real-time transmission of multimedia data and prolong the lifetime of sensor networks.
