Dsr

DSR is an acronym used in several different contexts, spanning computing, telecommunications, and energy management. In computing, Dynamic Source Routing (DSR) is a routing protocol for mobile ad hoc networks that uses source routing and on-demand route discovery. Packets carry the complete route in their headers, and nodes maintain a route cache of known routes. This approach allows rapid adaptation to topology changes common in highly dynamic networks, without relying on fixed infrastructure.

In telecommunications, Data Set Ready (DSR) is a control signal used in RS-232 serial interfaces. It is asserted by a data communications equipment device (the modem or DCE) to indicate that the connected data terminal equipment (the computer or DTE) can communicate. DSR works alongside other handshake lines such as Data Terminal Ready (DTR) and Clear to Send (CTS) to coordinate data transfer between devices.

In the energy sector, Demand-Side Response (DSR) refers to programs and technologies that reduce or shift electricity consumption during peak demand periods in response to price signals or incentives. Utilities and grid operators use DSR to improve reliability, manage peak loads, and potentially lower system costs. Implementations range from dynamic pricing and automated controls on heating, cooling, and industrial processes to manual demand-reduction programs.

Other specialized uses of the acronym exist, but these three represent some of the most common meanings. DSR thus highlights how the same letters encode distinct concepts across networks, communications, and energy management.
