Robot fabrication has always been a costly matter. Even for educational purposes, one will need to spend substantial amount of money for building single robot with limited capabilities. When it comes to development of higher capabilities and intelligence, more investment will be required. In this paper, we present details of a mobile robot that is specially designed and made to be used as a stand-alone...
Since the present algorithms are on the assumption of correct beacon information, when the network is attacked, especially the beacons are captured by opponents, all algorithms will not work. To address this issue, one attack-resistant nodes localization algorithm we call VDV-Hop(Voting DV-Hop) which is on the basis of DV-Hop algorithm and based on the voting mechanism is presented. This algorithm...
According to characteristics of coal mine goaf, a suitable routing mechanism based on LEACH protocol was proposed. The mechanism's improvement including two sides: Firstly, LEACH cluster heads selection mechanism was improved. Secondly a routing algorithm of wireless sensor network was designed with the multi-path routing mechanism. Finally, the NS2 simulation result show that this new routing mechanism...
Nowadays, according to the production and management on the offshore oil and gas platforms, the wireless sensor networks(WSNs) will have different reply to the platforms. For the offshore Oil and Gas platforms, switching from wired to wireless sensors, allowing data collection in remote or hostile areas. Reliability, power consumption and standard are three most important concerns that related to...
To deal with the challenges of Wireless Sensor Networks (WSN) in the smart grid, such as heterogeneous coexistence, spectrum scarcity, tremendous data processing and Security guarantees, revolutionary communication architecture is urgently demanded, a revolutionary communication paradigm termed as Wireless Cognitive Sensor Network (WCSN) whose basic idea is to incorporate cognitive radio capability...
More than a brief introduction to the linear technology in the field of wireless communications and radio and television within the wide application of linearization techniques to achieve a certain degree of difficulty, but the benefits of the system is to improve efficiency and save the volume and reduce costs. For each type of system characteristics and requirements of appropriate technology should...
The ZigBee is a low rate and low power networking technology for short range wireless communication. The study is provided the framework design of the internet of things using ZigBee technology. The ZigBee can make many RFID readers connected the networks wirelessly, and realize the data multi-points wirelessly gathering and transmission. To a certain extent “the conflict” questions, which the traditional...
The paper presents modern PLC's network to Physiological parameter monitoring technology. In this paper a founding method and implement of the system for personal and real-time monitoring is described, including the operation of the whole system. The tests demonstrate that the system is stable, reliable as well as high timely and accuracy. This paper accords with the trend that the network is becoming...
