The document presents a Distributed Three-hop Routing (DTR) protocol for hybrid wireless networks that incorporates features of both mobile ad-hoc and infrastructure wireless networks. DTR aims to improve throughput capacity and scalability by dividing a data stream into segments and transmitting them in a distributed manner across multiple base stations using both ad-hoc and cellular interfaces. It limits routing paths to three hops to reduce overhead. Theoretical analysis and simulation results show that DTR outperforms other routing protocols in terms of throughput, scalability, and mobility resilience with only minimal overhead.
