Modern multimedia sensor networks impose strict constraints on both the delay and energy consumption when time-critical data must be reported to the sink within a limited bandwidth without any loss. Failure to transmit an event to the sink occurs for many reasons, including inherence limitations of sensors, power consumption, and reliability. We propose a mathematical model for a novel quality-of-service...
Wireless multimedia sensor networking (WMSN) is an efficient technology and has been widely used in multimedia data transport and applications. The key to the success of multimedia data transport is the transmission quality. Real-time critical multimedia requires efficient routing for data delivery with guaranteed QoS. However, satisfying the stringent QoS requirements of multimedia transmission usually...
Mobile-Ad-Hoc network is a spontaneous, self configurable network consisting with multiple mobile nodes. All the nodes that are communicating in network acts like router and follow a random, ever-changing topology for sharing data on any scalable scenario. Due to this ever-changing network topology, one of the challenging tasks in multimedia ad-hoc network is to provide Quality of Services (QoS) during...
Nowadays, a recent trend has emerged in the Wireless Multimedia Sensor Networks (WMSNs) field. This trend consists of ensuring the best Quality of Experience (QoE) while transferring the multimedia content, as well as keeping an acceptable Quality of Service (QoS) concerning the scalar data transmission. However, ensuring this request needs more flexible and robust protocols at different communication...
The limited energy resources of sensor nodes pose challenging issues on the development of protocols for WSN. Introducing clustering into hierarchical protocol reduces number of transmission in the network to reduce their energy deception, then to maximize network lifetime. But the LEACH case is not really reliable in the case of real-time traffic because real-time applications are characterized by...
The ever-increasing demand for multimedia surveillance and monitoring has led to the deployment of wireless sensor networks capable of capturing multimedia contents along with the scalar data. However, most of the routing protocols designed for wireless sensor networks (WSNs) are meant only for homogeneous sensor networks in which all sensor nodes have same capabilities in terms of communication,...
In this paper, we propose a delay-aware multipath source routing (DMSR) protocol to provide QoS support for real-time multimedia applications in wireless ad hoc networks. Based on local information, node delay is calculated as metric for route path selection in the DMSR protocol. The metric takes into account the number of the neighbor nodes of the forwarding nodes, the channel busy time and the number...
Multicast services are used in emerging multimedia applications based on Quality of Service (QoS) development of multimedia group application and the construction of multicast routing tree is significant. Upper bound on the delay between sender and receiver is one of the common QoS constraints. Delay-constrained routing protocols are used to find paths subject to the delay constraint while efficiently...
