Cross Layer Approach Energy Efficient Transmission of Multimedia Data over Wireless Sensor Networks

Multimedia transmission in wireless multimedia sensor networks is often energy constraints. In practice the bit rate resulting from all the multimedia digitization formats are substantially larger than the bit rates of transmission channels that are available with the networks associated with these applications. For the purpose of efficient of storage and transmission of the content, the popular compression technique MPEG4/H.264 has been made used. To achieve better coding efficiency video streaming protocols MPEG4/H.264 uses several techniques which is increasing the complexity involved in computation at the encoder prominently for wireless sensor network devices having lesser power abilities. In this paper we propose energy consumption reduction framework for transmission in wireless networks so that well-balanced quality of service (QoS) in multimedia network can be maintained. The experiment result demonstrate that the effectiveness of the proposed approach in energy efficiency in wireless sensor network where the energy is the critical parameter.
