Wireless Communication

References: What is Covert Communication? Covert communication, or Low Probability of Detection (LPD) communication, is a security technique designed to hide the very existence of a transmission. Unlike standard encryption, which hides the content of a message, covert communication hides the act of communicating from an observant adversary, often referred to as a “warden” (Willie). ...

References: What is Electromagnetic Spectrum? The electromagnetic (EM) spectrum is the entire range of all types of electromagnetic radiation. Radiation is energy that travels and spreads out as it goes, the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of ... Read More

References: What is wireless channel? In wireless communication, a wireless channel refers to the physical medium, the air or space, through which electromagnetic signals travel from a transmitter to a receiver. Unlike a wired connection (like fiber optics or Ethernet cables) where the signal is contained within a physical “pipe,” a wireless channel is open ... Read More

References: What is opportunistic network coding? In the world of wireless communication, the biggest challenge isn’t just sending data, it’s doing so without creating a digital traffic jam. While traditional routers simply act as relay stations, a more intelligent approach has emerged: Opportunistic Network Coding. Instead of treating every packet as a solo traveler, we ... Read More

References: What is Network Coding? In traditional networking, routers act like simple relay stations i.e. they receive a packet and forward it toward its destination. However, this “forwarding-only” approach creates physical bottlenecks that limit how much data a network can handle. Network coding is a revolutionary paradigm that changes this by allowing routers to “mix” ... Read More

Now, network coding is the recent generalization of routing in which nodes can generate output data which is produced from encoding or applying certain functions on the previously received input ...

https://www.microsoft.com/en-us/research/wp-content/uploads/2007/07/tr-2007-90.pdf In traditional wireless communication, intermediate nodes (routers or relays) act like a postal service: they receive a packet, store it, and then forward it exactly as it was. Network Coding (NC) completely changes this. Instead of just forwarding, nodes are allowed to perform mathematical operations to combine multiple incoming packets into a single outgoing ...
