Wireless SAW resonant sensors have been widely used in many applications, especially in harsh environment. The sensor is detected when the echo signal spectrum processed by Fourier transform exceeds a threshold. Because of complicated noise and electromagnetic interference in wireless channel, the threshold should be adaptive to interference in order to detect the sensor accurately. However, few researches...
As the virtual backbone of the network, connected dominating set (CDS) plays an important role in supporting data communication, reducing the routing overhead, and enhancing the scalability of the network. Traditional CDS construction algorithms are usually applied to the networks with homogeneous nodes, e.g., a pure wireless sensor network. In the past few years, Wireless Sensor and Actor Networks...
In recent years, there has been a growing interest in equipping base-stations with renewable resources and batteries, with an aim to reduce the energy-related operational cost for cellular networks. To fully leverage the cost-saving potential of such base-stations, the design of joint resource-allocation and energy-control algorithms that take both the traffic-level dynamics and energy-level dynamics...
The cooperation among sensor nodes is a significant issue in large-scale, complicated Wireless Sensor Networks(WSN). Target tracking is a canonical application of WSN. The dynamic coalition mechanism in WSN for target detection is an important method to improve the tracking quality which saves much energy. An energy efficient coalition formation algorithm is needed because the energy resource of WSN...
Given the resource-constrained and distributed nature of Wireless Sensor Network (WSN), collaboration is very necessary for task execution. However traditional collaborative methods can not be applied to WSN directly. In this paper, we focus on coalition-based method of multi-nodes collaboration (CMMC) which is performed to achieve a maximum utility through collaboration while minimizing the communication...
