Based on the LEACH protocol and the Single-hop protocol, this paper proposes a new method to predict the lifetime and reliability of wireless sensor network directly. That is to say, the sensor nodes can be directly deployed without further simulation. Through a series of experiments to compare the two protocols have been several key conclusions: With the increase in sensor density, although the LEACH...
To solve the overlap problem in node selection process in order to fill the existing routing algorithms deficiencies, This paper designs a traditional Gossiping routing algorithm based on SPSO. At the same time, the paper gives the content and design steps of this algorithm. The simulation results show that the algorithm can effectively solve the problem of node selection.
Even though the wireless positioning in sensor networks has been extensively studied in the past decades, there is no contribution discussing positioning the receiver that belongs to another system, i.e., the third-party receiver. In this paper, we propose a new scheme to solve the problem by full-duplex rtechnique. In our scheme, we let the sensors conduct the full-duplex relay for the target receiver...
In this paper, a new decision fusion algorithm based on Dempster-Shafer theory (DST) and Bayes criterion for multiple hypotheses in heterogeneous wireless sensor network is proposed. Firstly, the two layer sensor fusion scheme is put forward to study the decision fusion rules of the multiple hypotheses multisensory systems. In the first layer, the optimal local decision fusion rule and the suboptimal...
There has been an increasing investigation in distributed radar sensor network (RSN) and MIMO-RSN, including waveform design, antenna strategy and spacetime coding, etc. However, distributed-RSN and MIMO-RSN are more like two parallel paths other than one research field in current literature. In this paper, we address the comparison between distributed-RSN and MIMO-RSN for target detection. We first...
Resource management for multitarget detection in Heterogeneous Sensor Networks (HSN) is an open research area. By considering communication capabilities, energy differences and mobility dissimilarities jointly, we propose a fuzzy logic system (FLS) and apply fuzzy c-mean (FCM) clustering to adaptively select sensors that report surrounding targets information for further data fusion. Monte Carlo simulations...
Remote medical monitoring system has being developed very fast in recent years. In order to predict complications before patient cause serious harm, we need a wearable, wireless and low power patient device to monitor their electrical charges at real time. In this paper we propose a mobile wireless Electrocardiograph monitoring and recording device based on OMAP processor. This solution takes the...
Flooding time synchronization protocol (FTSP) is an extendable, robust and steady protocol, which has high synchronization precision in wireless sensor networks. This paper improves the traditional FTSP, according to the characteristics of industrial wireless sensor networks. The key idea is that the node should avoid transmitting the time synchronization message with the rootID and seqNum, which...
Traditional CPU instructions provide limited support to the byte permutation operation which is frequently used in the various symmetric encryption algorithms. Due to this reason, researcher Ruby B. Lee at Princeton University presented the byte permutation instructions and proved that the byte permutation instructions played an important role on improving the performance of cryptographic algorithms...
In this paper, we present two practical algorithms for selecting a subset of channels in virtual multiple-input-multiple-output (MIMO) wireless sensor networks (WSNs) to balance the MIMO advantage consumption of sensor cooperation. If intracluster node-to-node multihop needs be taken into account, the maximum spanning tree searching (MASTS) algorithm, with respect to the cross-layer design, always...
In this paper we investigate a methodology named channel selection with the aim of balancing the multiple input multiple output (MIMO) advantage and the complexity of node cooperations for wireless sensor networks (WSN). In respect of cross-layer design, we propose the Maximum Spanning Tree Searching (MASTS) algorithm to select a set of subchannels that always provide a path connecting all sensors...
In this paper, we present singular-value decomposition- QR with threshold (SVD-QR-T) algorithm to select a subset of channels in virtual MIMO wireless sensor networks (WSN) in order to reduce its complexity and cost. SVD- QR-T selects best subset of transmitters while keeping all receivers active. The threshold is adaptive by means of fuzzy c-mean (FCM). Under the constraint of the same total transmission...
