Multimedia sensor networks have emerged due to the tremendous technological advances in multimedia hardware miniaturization and the application potential they present. However, the time sensitive nature of multimedia data makes them very problematic to handle, especially within constrained environments. In this paper, the authors present a novel approach based on continuous 3D real time reconst...

Multimedia data fusion in wireless sensor networks has attracted great attention in the literature. However the existing data fusion does not take into account the cooperative redundancy of audio data. In order to improve energy efficiency and extend network lifetime, the paper presents an integrated audio data fusion framework, which combines wavelet transform with seamless audio-editing techn...

Advancements in Complementary Metal Oxide Semiconductor (CMOS) technology have enabled Wireless Sensor Networks (WSN) to gather, process and transport multimedia (MM) data as well and not just limited to handling ordinary scalar data anymore. This new generation of WSN type is called Wireless Multimedia Sensor Networks (WMSNs). Better and yet relatively cheaper sensors – sensors that are able t...

Video and image sensors in wireless multimedia sensor networks (WMSNs) have directed view and limited sensing angle. So the methods to solve target coverage problem for traditional sensor networks, which use circle sensing model, are not suitable for WMSNs. Based on the FoV (field of view) sensing model and FoV disk model proposed, how expected multimedia sensor covers the target is defined by ...

Wireless multimedia sensor network is a type of sensor networks, which is capable to extort the nearby ecological information, locally processing it and then wirelessly transmit it to the base station. The large amount of data is processed and transmitted in the wireless multimedia sensor network so that high energy consumption which leads to packet error rate and inefficiency in bandwidth and ...

Wireless multimedia sensor networks (WMSN) are formations of a large number of compact form-factor computing devices that can capture multimedia content, such as video and audio, and communicate them over wireless channels. The efficiency of a WMSN heavily depends on the correct orientation (i.e., view) of its individual sensory units in the field. In this paper, we study the problem of self-or...

Mobile Ad Hoc Networks (MANET) can be considered as a class of unstructured networks created by a number of autonomous wireless and sensor nodes. The inherent characteristics of such networks have made specific applications, such as multimedia transfer and challenging. Basically, the functionality of a node and very few resources directly affect the delivery of packets which depends on the ...

We propose a simulation environment for networks for Wireless Multimedia Sensor Networks (WMSNs), i.e. networks with sensors capturing complex vectorial data, such as for example video and audio. The proposed simulation environment allows us to model the communication layers, the sensing and distributed applications of a WMSN. This Wireless Simulation Environment for Multimedia Networks (WiSE-M...
