Read MoreDifference Between Informed and Uninformed Search
In this post, we will understand the difference between informed search and uninformed search −Informed SearchThey contain information on goal state.It helps search efficiently.The information is obtained by a function that helps estimate how close a current state is, to the goal state.Examples of informed search include greedy search and graph search.It uses the knowledge in the process of searching.It helps find the solution quickly.It may or may not be complete.It is inexpensive.It consumes less time.It gives the direction about the solution.It is less lengthy to implement.Uninformed SearchThey don’t have any additional information.The information is only provided in the problem ...
Read MoreRadio Frequency IDentification (RFID)
Radio Frequency Identification (RFID) is the application of radio waves to read and capture information stored on tags affixed to objects. RFID readers are installed at tracking points and can read information from tags when they come into range, which can be of several feet radius. A tag need not be within direct line-of-sight of the reader to be tracked. RFID is used to check identities and track inventory, assets and people. RFID tags can be attached to a variety of objects like cash, clothing, baggage, parcels, and even implanted in animals and people.Working PrincipleThere are two parts in a ...
Read MoreThe Bluetooth Frame Structure
The Bluetooth network technology connects mobile devices wirelessly using short-wavelength, ultra-high frequency (UHF) radio waves over a short range to form a personal area network (PAN). Data is transferred between the Bluetooth devices as data frames. Two basic frame formats are defined, for transmitting data at basic data rate and for transmitting data at enhanced data rate.Bluetooth Frame Format with Basic Data RateA Bluetooth frame with basic rate has three parts, access code, header and data as shown in the following diagram−The various fields are−Access Code− A 72-bit field containing synchronization bits to identify the master.Header− A 54-bit field containing ...
Read MoreAsynchronous Connection-Less (ACL) Link
Bluetooth link layers define two types of data links, Asynchronous Connection-Less (ACL) Link, being one of them. It is the type of link used for transmission of general data packets using Bluetooth connection. ACL is a point – to – multipoint link used for irregular traffic between a master device and one or more slave devices.Features of Bluetooth ACL linksACL is a packet oriented link, i.e. the link establishes a packet – switched network.ACL is used for transmission of data traffic which are delivered at irregular intervals, where maintaining data integrity is more important than the time latency.Both symmetric and ...
Read MoreSynchronous Connection-Oriented (SCO) Link
Bluetooth link layers define two types of data links, Synchronous Connection Oriented (SCO) link, being one of them. SCO is a symmetric, point-to-point link between the master device and the slave device connected via Bluetooth.Features of Bluetooth SCO linksIn SCO, a dedicated, point-to-point link is established between the master device and the slave device before communication starts.SCO is a symmetric link, i.e. fixed slots are allocated for each direction.Since fixed slots are reserved, SCO provides a circuit switched connection.SCO radio links are used for time critical data transfer, particularly for voice data.Both the master and the slave device transmit encoded ...
