“…El esquema puede ser combinado en conjunto con estrategias adicionales, por ejemplo: enrutamiento multi-trayectoria, diferenciación de servicios, predicción de distorsión en el caso de tráfico de video y monitorización de rutas para evitar sobrecarga. En [9], [10] y [11] se presentan algunos trabajos de éste tipo. La gestión de energía a nivel de red también puede ser direccionada a través de métricas indirectas, como por ejemplo el retardo.…”

Abstract-Energy constraints on wireless nodes represent a current field of research. Such restrictions are particularly significant because of the great amount of features and applications currently available on devices, which contribute to dramatically increase energy consumption. However, when transmitting delay-sensitive data, such as multimedia streaming, a balance between energy optimization and quality of service is required. In this sense, there are many works that address this issue from different layers of network architecture separately; however, a more efficient solution could be achieved by combining the management capabilities of the different layers and the joint use of such information, which is called a crosslayer mechanism. Moreover, despite the fact that the IEEE 802.11 standard defines an energy management mechanism at MAC level, it is envisaged only for structured networks, leaving just general guidelines for other kind of networks, such as AdHoc networks. Therefore, as a first step towards the design of a cross-layer scheme, this paper analyzes the flaws of IEEE 802.11 standard as regards the infrastructureless mode and proposes an optimization mechanism for energy management in Ad-Hoc networks. The proposed approach is based on a buffering mechanism, which is able to increase power-saving periods of time in Ad-Hoc nodes. Simulations using NS3 indicate that it is possible to obtain higher levels of residual energy at the end of a transmission using the proposed scheme.

“…Moreover, it has a higher delivery ratio and consumes less energy than state-of-the-art solutions. Kandris et al [122] have proposed a hierarchical routing protocol called PEMuR (Power Efficient Multimedia Routing) which is devoted to video routing over a stationary WMSN while satisfying both energy efficiency and QoS requirements. In this solution, the CH selects the path to the base station (BS) whose remaining energy after transmission will be the highest among all of the possible paths.…”

“…Multimetric protocols use various network measurements to satisfy multiple application needs. For example, recent application-specific routing protocols have proposed to combine energy efficiency with QoS requirements [122][123][124] or security concerns [125]. These research works consider the energy reserves of nodes along with video distortion, packet error rate or node reputation.…”

The design of sustainable wireless sensor networks (WSNs) is a very challenging issue. On the one hand, energyconstrained sensors are expected to run autonomously for long periods. However, it may be cost-prohibitive to replace exhausted batteries or even impossible in hostile environments. On the other hand, unlike other networks, WSNs are designed for specific applications which range from small-size healthcare surveillance systems to large-scale environmental monitoring. Thus, any WSN deployment has to satisfy a set of requirements that differs from one application to another. In this context, a host of research work has been conducted in order to propose a wide range of solutions to the energysaving problem. This research covers several areas going from physical layer optimization to network layer solutions. Therefore, it is not easy for the WSN designer to select the efficient solutions that should be considered in the design of application-specific WSN architecture.We present a top-down survey of the trade-offs between application requirements and lifetime extension that arise when designing wireless sensor networks. We first identify the main categories of applications and their specific requirements. Then we present a new classification of energy-conservation schemes found in the recent literature, followed by a systematic discussion as to how these schemes conflict with the specific requirements. Finally, we survey the techniques applied in WSNs to achieve trade-off between multiple requirements, such as multi-objective optimisation.

“…The advantage of scheduling algorithm is that it enables the reduction in video transmission rate by the minimum increase in distortion. It also predicts the resulted video distortion due to any error pattern [26].…”
