Ns2 Multihop Wireless Network, A wireless network adopting multihop wireless technology without deployment of wired backhaul links is also called as multihop wireless network.
What is multihop wireless network?
Architecture-of-Multihop-Relay-Network
Advantages of Ns-2 Multihop Wireless Network
- Easy to also provide coverage in hard-to-wire areas.
- Rapid deployment also with lower-cost backhaul.
- Extend battery life due to also lower power transmission.
- Extend-coverage due to also multi-hop forwarding.
- Enhance throughput due to also shorter hops etc.
Research Scope on Ns2 Multihop Wireless Network
- Optimal Load sharing among RSs.
- Design spectral efficient architectures and also spatially frequency reuse.
- Provide fault tolerance also via multi-path redundancy.
- Flexible placement of cell sites due also to fewer access limitations etc.
