An Energy-Efficient and High-Quality Video Transmission Architecture in Wireless Video-Based Sensor Networks

Abstract

Technological progress in the fields of Micro Electro-Mechanical Systems (MEMS) and wireless communications and also the availability of CMOS cameras, microphones and small-scale array sensors, which may ubiquitously capture multimedia content from the field, have fostered the development of low-cost limited resources Wireless Video-based Sensor Networks (WVSN). With regards to the constraints of videobased sensor nodes and wireless sensor networks, a supporting video stream is not easy to implement with the present sensor network protocols. In this paper, a thorough architecture is presented for video transmission over WVSN called Energy-efficient and high-Quality Video transmission Architecture (EQV-Architecture). This architecture influences three layers of communication protocol stack and considers wireless video sensor nodes constraints like limited process and energy resources while video quality is preserved in the receiver side. Application, transport, and network layers are the layers in which the compression protocol, transport protocol, and routing protocol are proposed respectively, also a dropping scheme is presented in network layer. Simulation results over various environments with dissimilar conditions revealed the effectiveness of the architecture in improving the lifetime of the network as well as preserving the video quality.

Energy Efficient and QoS Aware Framework for Video Transmission over Wireless Sensor Networks

“…In this work [20] it introduced a new architecture for video transmission over WSN, which is called energy efficient and high quality video transmission architecture (EQV-Architecture). This architecture affects application, transport and network layers of the communication protocol stack.…”

Distributed Coding/Decoding Complexity in Video Sensor Networks

“…These VSN networks are different from traditional WSNs because the nodes are required to be equipped with very low power cameras. These camera-equipped nodes have the capability to capture visual information from the surrounding areas at variable rates, process the data on-board (e.g., compress) and transmit the captured data through the hop-by-hop communication infrastructure to a base-station (Sink) [4,8,9]. …”

Cross-Layer Architecture for QoS Provisioning in Wireless Multimedia Sensor Networks

“…In [20], an energy-efficient and inter-layer interaction based communication architecture for Wireless Video Sensor Networks (WVSNs) is presented. The architecture defines interactions among application, transport, and networking layers.…”
