The introduction of multimedia capable sensors has posed new challeges for classic Wireless Sensor Networks that are henceforth required to provide both power and quality efficent routing. This paper proposes an innovative protocol for power and perceived QoS aware routing of multimedia content over Wireless Multimedia Sensor Networks. The proposed scheme comprises the advantages of both energy efficient...
A cross-layer communication protocol called VSN-module is introduced for wireless video sensor networks based on ultrawideband (UWB) radio technology at the physical layer. The core of our solution is a distributed path reservation scheme which routes video traffic from sources (sensors) to a sink. The path establishment takes into account the specific requirements of video flows such as bandwidth,...
Wireless video sensor networks (WVSNs) bring a new set of design challenges due to their specific application requirements in terms of latency, bit rate, and power consumption. In this paper, we propose an application layer power-congestion-distortion (P-C-D) optimized multi-path transmission scheduling algorithm. The algorithm utilizes existing techniques and protocols on the various layers and is...
