QoS-aware distributed adaptive cooperative routing in wireless sensor networks
In this paper, we investigate a cooperative routing problem in time-varying Wireless Sensor Networks (WSNs) targeting the achievement of quality-of-service guarantees in delay and reliability domains. We develop a distributed adaptive cooperative routing protocol, called DACR, that exploits cooperative communication on top of delayand energyaware end-to-end routes and optimizes the trade-off be...
متن کاملCooperative diversity routing and transmission for wireless sensor networks
In this study, the authors present a novel design framework aimed at developing ‘cooperative diversity’ in 802.11-based wireless sensor networks. The proposed scheme is a combination of a time-reversed space-time block code scheme at the physical layer and a cooperative routing protocol at the network layer. The core feature of this architecture is that the multiple routes are capable of assist...
متن کاملQoS in Wireless Sensor Networks
Wireless Sensor Networks (WSNs) have been envisioned as a new and effective means for creating and deploying previously unimaginable applications. These networks generally have the capabilities of observing the physical phenomena, communication, data processing and dissemination. Limited resources of sensor nodes like energy, bandwidth and processing abilities, make these networks excellent can...
متن کاملCross Layer Design for Cooperative Transmission in Wireless Sensor Networks
Several protocols and schemes have been proposed to reduce energy consumption in Wireless Sensor Networks (WSNs). In this paper we employ farcoopt, a cross layer design approach with the concept of cooperation among the nodes with best farthest neighbor scheme to increase the Quality of Service (QoS), reduce energy consumption, increases performance and end-to-end throughput. We present coopera...
متن کاملEnergy-Efficient Broadcasting with Cooperative Transmission in Wireless Sensor Networks
Broadcasting is a method that allows the nodes in a wireless sensor network to share the data efficiently among other nodes. Due to the limited energy supplies of a sensor node, energy-efficiency is a crucial aspect in the design of broadcasting protocols. In this paper, we analyze the energy savings provided by a novel form of cooperative broadcast transmission, called the Opportunistic Large ...
