In current days, sensor nodes are deployed in hostile environments for various military and commercial applications. Sensor becoming faulty having adverse effects the network if they not diagnosed inform fault status to other nodes. Fault diagnosis is difficult when behave some times provide good data at times. The intermittent disturbances may be random or kind of spikes either regular irregular intervals. literature, algorithms based on statistical methods using repeated testing machine...
Wireless sensor networks (WSN) continue to get tremendous popularity because of the increasing number applications. Some times few nodes are unable send correct data fusion center or neighbour node. Since network is unaware faulty status node, so performance degrades more. The received from node can treat as outliers. So that a statistical test be used identify outliers by In this paper neighbouring coordination based self detectable distributed fault detection algorithm and Z-test proposed....
In this study, the authors propose a hybrid power line communication (PLC)/visible light (VLC)/radio frequency (RF) fronthaul with fibre‐based wired backhaul system to support massive number of smart devices (SDs). Since signal‐to‐noise ratio‐based access point (AP) association and bandwidth (BW) allocation for each SD do not necessarily improve capacity, they novel efficient AP BW strategies maximise sum rate capacity (SRC) under consideration. An optimisation problem is formulated SRC as...
A distributed fault identification algorithm is proposed here to find both hard and soft faulty sensor nodes present in wireless networks. The distributed, self-detectable, can detect the most common byzantine faults such as stuck at zero, one, random data. In approach, each node gathered observed data from neighbors computed mean check whether or not. If a found presence of node, then compares with predict probable status. final status determined by diffusing information neighbors. accuracy...
The presence of soft faulty sensor nodes in wireless networks (WSNs) creates problem for maintaining the consistent performance over entire life span. For this, a distributed fault detection algorithm is proposed which based on neighboring coordination technique. node characteristics are accumulated at particular time instant to compute status. In this approach number message exchange identify sensors less and also saves substantial amount energy nodes. implemented NS3. simulation result...
Wireless sensor networks (WSN) have been proposed as a solution to environment sensing, target tracking, data collection and others. WSN collect an enormous amount of over space time. The objective is estimate parameter or function from these data. Learning used in detection estimation problems when no probabilistic model relating observation. This paper investigates general class distributed algorithms for processing, eliminating the need transmit raw central processor. can provide...
Since sensor networks can be thought of as a distributed database system, several architectures proposed to interface the application network through querying protocol. However are so massively distributed, careful consideration should put into efficient organization data and execution queries. Here we consider problem information discovery in densely deployed wireless Sensor Network (WSN) where initiator search is unaware target information. A new type protocol based on Increasing Ray...
A novel method of robust parameter estimation IIR system in presence impulsive noise is proposed here. The conventional squared error cost function based algorithm fails to provide desired performance, if the data contaminated with noise. Thus a computationally efficient Hubers used here alleviate adverse effect But, inherent property local minima problem, where gradient can not be used. Therefore, parameters estimated using modified particle swarm optimization function. simulation results...
