Accurate and fast wireless link quality assessment (LQA) for wireless channels would bring huge benefits for mobile multi-hop and multi-rate wireless ad hoc and sensor networks in the form of improved end-to-end performance. In this paper, we propose a novel LQA method based on cross-layer information. The method is implemented in a real test-bed, which is based on IEEE 802.11b/g, and achieved a significant LQA improvement up to 50% in mobile scenarios without introducing overhead. The effectiveness of accurate and fast LQA is demonstrated by feeding it into the routing layer to enable the route decisions to adapt faster during changing situations, especially in mobile scenarios. The experiment results show that the proposed LQA method can lead to faster and smarter routing decisions and higher end-to-end throughput compared to traditional methods, which only use hello packets to determine the link quality in mobile scenario.

IMPURITIES IN NI3FE MAGNETIC-ALLOYS MATYSINA, ZA; Mehrabov, Amdulla; BABAEV, ZM; ZAGINAICHENKO, SY (1987-01-01) Abstract - The sensing coverage area of surveillance wireless sensor networks, which is determined by applying the Neyman-Pearson detection rule, is considered. Using a graph model for the perimeter, the weakest breach path is found through Dijkstra's shortest path algorithm. The breach probability is a critical parameter for assessing the required number of sensor nodes and the surveillance performance of the network. Analysis indicates that for the Neyman-Pearson detection model, the most significant para...
A Survey on Multipath Routing Protocols for QoS Assurances in Real-Time Wireless Multimedia Sensor Networks Hasan, Mohammed Zaki; Al-Rizzo, Hussain; Al-Turjman, Fadi (2017-01-01) The vision of wireless multimedia sensor networks (WMSNs) is to provide real-time multimedia applications using wireless sensors deployed for long-term usage. Quality of service assurances for both best effort data and real-time multimedia applications introduced new challenges in prioritizing multipath routing protocols in WMSNs. Multipath routing approaches with multiple constraints have received considerable research interest. In this paper, a comprehensive survey of both best effort data and real-time m...
On the Smoothing Factor for Rate Adaptation in IEEE 802.11b/g Mobile Multi-Hop Networks Zhou, Jinglong; Onur, Ertan; Jacobsson, Martin; Niemegeers, Ignas (2009-01-01) IEEE 802.11b/g networks support multiple rates and rate adaptation mechanisms provide the ability to select the adequate rate intelligently. Prior work on the rate-adaptation focuses on stationary scenarios, such as mesh networks. The effect of the smoothing of the rate adaptation is not a well-studied topic in the mobile scenarios such as IEEE 802.11 multi-hop networks. In this paper, we use an experimental method to evaluate the one-hop performance and the routing decisions of a well-known rate adaptation...
AN ADAPTIVE HYBRID ARQ SCHEME FOR SLOWLY TIME-VARYING COMMUNICATION CHANNELS MEMISOGLU, AT; BILGEN, S (1994-04-14) An adaptive hybrid ARQ scheme for slowly timevarying channels that aims to maximize the average throughput under a given reliability constraint is presented. Punctured convolutional codes and the Viterbi algorithm with the Yamemoto-Itoh retransmission protocol are employed for encoding and decoding, respectively. A procedure based on exponentially weighted moving averages is developed to detect channel state changes
A method for providing energy efficient neighborhood maintenance in MANETs Ünlü, Berk; Özceylan, Baver; Baykal, Buyurman (2016-12-05) Mobile ad-hoc networks (MANETs) are widely employed in many wireless networks, e.g. tactical area networks, due to its several advantages. Most of the MANETs must meet certain quality of service requirements such as high link reliability, low energy consumption and high throughput. However, major issues like interference dramatically degrade the service quality. In order to provide a high quality of service, an efficient control protocol, which handles the interference problem in neighborhood maintenance wh...
