In wireless sensor networks, the resilient data fusion is an effective method to deal with the malicious attack while it is always energy exhausting, and does not consider the fusion function and the attack detection synthetically, which may affect the accuracy of fusion result. A novel information utility measures based resilient data fusion algorithm is proposed in this paper trying to solve this...
In large-scale Wireless Sensor Networks (WSNs), leveraging data sinks' mobility for data gathering has drawn substantial interests in recent years. Current researches either focus on planning a mobile sink's moving trajectory in advance to achieve optimized network performance, or target at collecting a small portion of sensed data in the network. In many application scenarios, however, a mobile sink...
Multiple Channel Design (MCD) has been adopted widely in wireless networks to increase throughput and reliability with relatively less energy consumption. Due to physical restrictions of sensor nodes, applying multiple radio channels in sensor networks poses significant challenges, particularly on energy consumption. To address such challenges, we propose an energy-aware MCD scheme called SmartChannel...
In Wireless Sensor Networks (WSN), data gathering using mobile sinks typically incurs constant propagation of sink location indication messages to guide the direction of data reporting. Such behavior is undesirable, especially when the sensor network scale increases, as frequent message flooding will cause serious congestion in network communication and significantly impair the sensor network lifetime...
Based on the model of resilient data aggregation in wireless sensor networks, two attack detection algorithms by means of % -testing were proposed in this paper according to clustering uniformly or not, namely the CTUC (chi-square test for uniform cluster) algorithm and CTUUC (chi-square test for un-uniform cluster) algorithm. By applying % -testing with some priori knowledge about the system, the...
Resilient aggregation is an effective method to deal with the malicious attack on input data of the aggregation function. However, the current resilient algorithm is always energy exhausting, and does not consider the aggregation function and the attack detection synthetically, which may affect the accuracy of aggregation result. A novel resilient data aggregation algorithm is proposed in this paper...
This paper presents an application-driven multi-agent architecture to address the evolving use of wireless sensor networks as an enabling technology for autonomous residential energy management. Paradigm shifts in the electrical utility industry are changing the requirements for isolated residential devices. Dynamic electricity pricing rather than static flat rates requires increased automation and...
