Energy-Efficient QoS Routing in Wireless Multimedia Sensor Networks

Multimedia sensors are attracting the attention of the researchers increasingly, and have shifted the focus from traditional scalar sensors to sensors equipped with multimedia devices. The characteristics of multimedia services impose more resource constraints that involve energy consumption, memory, buffer size, bandwidth, and processing capabilities. Existing routing solutions used in wireless multimedia sensor networks suffer from limitations in term of QoS and energy efficiency. In this paper, we propose a new QoS routing solution to increase the energy efficiency while guaranteeing the QoS requirements of the multimedia services over the wireless sensor networks.
