A multimedia wireless sensor network, a routing protocol plays an important role in saving the limited resources of sensors. It allows a node to transmit a multimedia content to the sink node, an image in our case. Also, WMSN are used in Internet of Things to serv different purposes in order to make our world smarter. In this paper, we are going to use the Castalia simulator to test different configurations...
Due to complex surveillance in environment, more and more wireless multimedia sensor networks (WMSNs) is becoming an important hot problem in network research area. Especially, the QoS-controlled architecture is a key and significant problem. Based on the distributed policy and three-dimensional hierarchy protocol model, a novel QoS architecture for distributed control is introduced and analyzed in...
The IP Multimedia Subsystem (IMS) aims to provide cellular access to all the services that the Internet offers; it is an overlay control layer on top of an IP layer. Wireless Sensor Networks (WSN) with mobile sinks are useful in a wide range of scenarios since they can improve the overall network lifetime and increase data capacity. Combining the capabilities of IMS with the rich set of contextual...
Wireless actuators are small scale devices that can receive/accept instructions and act on their environment. The IP Multimedia Subsystem (IMS) is a key component for 3G networks. It aims at seamless provisioning of multimedia services. Combining actuation capabilities with IMS capabilities will certainly enable novel value added services. This paper proposes an architecture for the integration of...
In this paper, we describe a heterogeneous peer-to-peer network testbed, which is developed as part of a joint research project to investigate novel resource discovery and content distribution protocols in a heterogeneous wired/wireless environment. We describe the testbed requirements, the testbed architecture, the multi-functional wireless node, and the software architecture. We also describe some...
Wireless Multimedia Sensor Networks (WMSNs) is comprised of small embedded video motes capable of extracting the surrounding environmental information, locally processing it and then wirelessly transmitting it to parent node or sink. It is comprised of video sensor, digital signal processing unit and digital radio interface. In this paper we have surveyed existing WMSN hardware and communication protocol...
In this paper, we proposes a cognitive cross-layer architecture for the cognitive ad hoc networks, where each node in the networks can sense and learn from wireless environment, network environment and user's requirements, and then it will respond the changes of environment by adapting system parameters and network services based on the learned results. In this way, it can provide the end-to-end goals...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
