The sensing, computing, and control potential of smartphones remains to be fully explored in automatic control applications. In this paper, we control the angular position of a motor test-bed using feedback from the embedded motion sensors of a smartphone while it is mounted to the test-bed. The smartphone hosts an interactive user interface which students and researchers can use to quickly and easily...
Adjusting nodes positioning to satisfy the needs of network connectivity and power conservation in wireless sensor networks (WSN) is not a trivial task. Too far node distance may result in unreachable transmission while too near node distance not necessarily guarantee nodes connection. By knowing an acceptable distance range to position nodes in the networks, it can greatly help researchers to better...
Wireless sensor network (WSN) is commonly used for localization analysis. Through sniffing receive signal strength indication (RSSI) in WSN system, localization of higher RSSI is connected automatically. This paper proposes the Raspberry-Pi (RasPi) based sensor node to sniffing RSSI and automatically connect the device to strongest RSSI. The RasPi brings the advantages of a personal computer (PC)...
The coverage is a critical issue in WSNs and considered as a measure of the service quality of WSNs. We proposed a coverage optimal algorithm based on Virtual Distance (VD) to enhance the coverage of WSNs after initial random placement. We define the ideal position of node related to its neighbor, and then the distance vector of one node's real position to ideal position is defined as virtual distance...
Today the world is under virtually constant attack, targeted by increasingly sophisticated and well funded attackers. The increasing efficacy of cyber threats continues to highlight the inadequacies of traditional defense mechanism such as firewalls and Intrusion Detection System. The security analyst however focuses on finding the technical deficiency but do not consider the adversaries motivations...
Concentration of Carbon monoxide (CO) and Carbon dioxide (CO2) that high in the air is very dangerous for human life. Carbon monoxide is a poisonous gas that damages the circulation of oxygen in the blood when inhaled, while carbon dioxide is one of the gases that cause global warming. Both gases are classified as colorless and odorless gas so that the necessary special tools to monitor their concentration...
Thanks to the advancing Internet of Things(IoT) technologies, various applications have been developed to monitor or react with real-time sensor data, which is detecting the environment or human condition. However, since the communication methods vary with different sensors and platforms, it increases the work when develop applications among multi platforms. In this paper, a network structure is proposed...
In order to solve the problem of shortage of workers in large hospitals, this study design a kind of short distance wireless communication system based on brain-computer-interface (BCI) technology, it chooses the ultra-low power MCU MSP430F5438 and nRF24L01 as the core, and it includes the design of Lab view platform, brain electrical simulator, nRF24L01 wireless transceiver system and voice prompts...
Wireless sensor and actor networks (WSANs) deployed in a harsh environment may suffer simultaneous failures causing the network to be partitioned into disjointed parts. Connectivity restoration of these partitions is a vital issue for the reliability of the network mission. Most of the existing works in the literature mainly focus on restoring network connectivity take into account number of moving...
THESEUS is an energy-efficient routing system for Shared Sensor Networks (SSNs), with the primary goal of extending network lifetime. THESEUS has two features that distinguish it from other works found in the literature. First, it saves SSN nodes energy by using a packet aggregation algorithm, which reduces the number of transmissions. Second, THESEUS balances energy usage in the whole SSN by its...
In this paper extension to LEACH protocol i.e. Modified LEACH protocol has been analytically and critically analyzed. It has been shown that the hard threshold value in Modified LEACH protocol has a direct impact on the network lifespan of a wireless sensor network. More the initial energy more will be the net lifetime of the network, as the number of alive nodes will be more. Simulation and analytical...

Now a days Internet Technology leads to the expansion of new class of network called as Wireless Mesh Networks (WMNs). Which contains mesh topology arrange across different district performing various tasks such as data aggregation, communication etc. Energy is very big issue in Wireless Network. So, in this paper we used the Two Hop Clustering based approach which optimizes the energy in Wireless...
Wireless sensor networks (WSNs) are collection of sensor nodes that unite together to monitor an environment or a system. Due to abundant workload on node near the sink makes faster energy depletion than other nodes. Due to this, lifetime of WSNs to some amount, is resolved by the power consumption between sensor node & sink. Hence, CSMA/SF is used to reduce power consumption for sensing nodes...
