This document discusses hybrid wireless networks (HWNs) and some of their advantages over traditional wireless networks. It outlines the classification of HWN architectures and some routing protocols that have been proposed for different HWN types. Some key challenges of routing in HWNs are scalability, overhead from the presence of base stations and wired backbones, and high routing overhead. The document proposes looking at overhead and scalability issues for routing in HWNs.

- 5. Why hybrid wireless network Wireless network is two different types Base station oriented wireless network (BS) Ad hoc wireless network (Ad Hoc) Both have some challenges Capacity (Ad hoc) Handoff (BS) Bandwidth (Ad hoc ) BS failure ( BS) Weak connection (Ad hoc) HWN introduced for overcome those challenges SVS COLLEGE OF ENGINEERING

- 7. Classification of Architecture Hybrid Architectures Host-cum- Relay Stations Dedicated Relay Stations Multi mode Single mode Multi mode Single mode SVS COLLEGE OF ENGINEERING
- 8. Host-cum-relay stations The dedicated relay stations do not originate data traffic on their own and assist in forwarding for the sender. Single-Mode Systems MHs operate only multi-hop mode. E.g. Multi hop Cellular Network (MCN) Multi-Mode Systems The mobile hosts act either in single-hop mode or in multi-hop mode depending on the architecture. E.g. Directional throughput-enhanced Wireless in Local Loop (DWiLL) SVS COLLEGE OF ENGINEERING
- 9. Dedicated relay stations Dedicated relay stations are used for relaying data traffic Single-mode systems E.g. Self-Organizing Packet Radio Ad hoc Network Overlay (SOPRANO) Multi-mode systems E.g. integrated Cellular and Ad hoc Relay system (iCAR) SVS COLLEGE OF ENGINEERING
- 10. Routing protocols Base-Assisted Ad Hoc Routing protocol (BAAR) It was propose for the Multi Hop Cellular Network (MCN) architecture It efficiently makes use of the BS for Routing Base-Driven Multi Hop Bridging Routing protocol (BMBP) It was proposed for the Multi Hop Wireless LANs (MWLANs) AP compute the routing table is called bridging table It includes next hop node & hop count SVS COLLEGE OF ENGINEERING
- 11. Routing protocols (cont.. ) SMCN Routing protocol (SMRP) It was proposed for Single Interface Multi Hop cellular Network (SMCN) architecture It provide mechanisms for routing both control and data packet through multiple hops DWiLL Routing protocol (DRP) It was proposed for the Directional Throughput – enhanced Wireless in Local Loop (DWiLL) SVS COLLEGE OF ENGINEERING
- 12. Challenges in Routing Presence of Base Station Presence of High speed wired back bone High routing over head Scalability SVS COLLEGE OF ENGINEERING
- 13. Conclusion Hybrid wireless networks have proven to be a better network structure for the next generation networks. However, little effort has been devoted to supporting QoS routing in hybrid networks SVS COLLEGE OF ENGINEERING
