I have learned that
Limited broadcasting is broadcasting in same network.
Directed broadcasting is broadcasting in other network.
But what about the broadcast in all network?

I have a router with IP addresses 192.168.0.x. (1st network).
Connected to a LAN connection is a second router with addresses 192.168.1.x. (2nd network).
How do I make it possible for both networks to see each other?
I'm asking without knowing anything about this. How can I connect two PNP Proximity Sensors to the computer via Ethernet and receive a signal? Is it possible to connect such sensors based on IP? Then I want to read socket. thanks
I have recently come across Adaptive AutoSAR, I see all the Domain Controller/ECUs on the Adaptive side uses Ethernet Switch port to connect to other ECUs or Gateways. I know Switch has many features, but Could you please explain
1. Can we use inbuilt Ethernet Ports for doing the same functionality. or
2. What can the Switch provide which Ethernet Port doesn't.
Unlike CAN and other communication interfaces, SOC could not direct connect by Ethernet port interfaces. A second-layer switch should be used to be divided the network into different collision domains.
I'm trying to host a wifi from either a lan connection (if available) or either sharing a network.
I did use the tutorial : https://kaiuwe.hüber.de/raspberry-pi-wifi-repeater-ohne-adapter/
But this just acts as a repeater ...
My expectation is a possibility to share wifi over wlan or when a lan connection is active share the wifi from lan.
I'm not sure you know enough about WiFi or TCP/IP networking to ask your question sensibly. What do you mean by "share WiFi?" There are two common scenarios:
Your Pi works as a WiFi bridge to an Ethernet LAN. In this case, the WiFi and the LAN are the "same" network, just different media. For instance, if your LAN uses the IPv4 address 192.168.42.0-255, your WiFi users will also share this network.
Your Pi works as a WiFi router, with an Ethernet LAN as the "uplink." In this case, your WiFi network has its own range of addresses, probably managed by your Pi, and the Pi works as a router between the WLAN and the LAN. This is like what most home WiFi access points do. (You will probably need to have the Pi do Network Address Translation as well. For some reason, Linux people insist on calling this 'masquerading.')
If you can clarify which of those you want to do, I could provide some pointers going forward. You many want to do some reading on the basics of TCP/IP networking first. If you don't know how a bridge and a router differ, you won't be able to ask useful questions.
We used nearby connection and tried both star and cluster strategy and noticed that in star strategy bandwidth is very high as compared to the bandwidth in cluster strategy.
The network structure which cluster strategy uses, best matches our requirements but we want to have a high bandwidth as we get in star strategy.
If its possible then how can we achieve this?
tldr; You can get high speeds with P2P_CLUSTER but only if both devices are connected to the same router.
The reason P2P_STAR and P2P_POINT_TO_POINT are more restrictive is so that technologies with the same restrictions can be used. P2P_STAR can do everything P2P_CLUSTER can do, but can additionally use Wifi hotspots (and similar technologies, like Wifi Direct). Likewise, P2P_POINT_TO_POINT can do everything P2P_STAR can do, but also with the inclusion of Wifi Aware. It's a tradeoff between flexibility and bandwidth.
As of today, these are the technologies behind each strategy. (Note: We're constantly adding more, and are open to suggestions).
