DSR Meaning and
Definition
-
DSR stands for "Dynamic Source Routing." It is a routing protocol used in wireless ad hoc networks, which allows nodes to dynamically discover and maintain routes to communicate with each other. This type of network does not have a fixed infrastructure such as routers or access points, and instead, each node can act as a router itself. DSR is an on-demand routing scheme, meaning that routes are only discovered and maintained when needed.
In DSR, when a source node wants to send data to a destination node, it does not have a pre-established route. Instead, it initiates a route discovery process by broadcasting a Route Request (RREQ) message to its neighboring nodes. The RREQ message contains the source and destination addresses. As the RREQ message propagates through the network, each intermediate node appends its own address to the "route record" in the message. When the RREQ message reaches the destination node or a node with a route to the destination, a Route Reply (RREP) message is sent back to the source node, containing the complete route.
DSR also supports route maintenance and error handling. If a link in the established route breaks or becomes unavailable, DSR uses route error messages to inform the affected nodes and trigger route reconstruction.
Overall, DSR provides an efficient and flexible routing solution for wireless ad hoc networks, ensuring reliable communication in dynamic and changing network topologies.
