Abstract

Multimedia applications have become an essential part of our daily lives, and their use is flourishing day by day. In Wireless Multimedia Sensor Networks (WMSNs), large volume of multimedia data is transmitted through the network. If the traffic load is greater than the available capacity of the sensor network, congestion occurs and it causes buffer overflow, packet drop, deterioration of network throughput and effect quality of service (QoS). The limited bandwidth should be adjusted for the packets with different priorities precisely. To emphasize the problem, the paper provides A New Approach for Traffic Management in Wireless Multimedia Sensor Network. According to the paper, sensor nodes in one collision area can adjust their sending states adaptively based on packet priority. To improve the received video quality in base stations, proposed technique keeps the I-frames and ignores the other less important frame types of compressed video. Also retransmissions of lost packets are provided with different priorities for enhancing the system performance. The simulations show that the bandwidth adjustment can protect the packets with high priority effectively, and the performance of the retransmission is well positioned to meet the requirement of the multimedia applications. MATLAB is used for simulation purpose.
