This document provides an overview and comparison of two reactive routing protocols for mobile ad hoc networks (MANETs): Dynamic Source Routing (DSR) and Ad Hoc On-Demand Distance Vector Routing (AODV). It describes the key characteristics of each protocol, including their approaches to route discovery and maintenance. DSR uses source routing, storing the complete hop-by-hop route in the packet header. AODV uses next-hop routing with destination sequencing to maintain routing tables. Both protocols operate reactively, searching for routes on demand, but AODV additionally requires periodic beacon messages for neighbor detection. The document compares the performance and overhead of each protocol.
