Routing Protocols means the set of defined rules used by the routers to perform the communication between source & destination nodes in the simulations or real time implementations. The routing protocols used to reducing the internet traffic across single or multiple networks
The three types of Network Routing Protocols are , available like,
Static routing is a process in which we have to manually add routes in routing table. Default Routing is the method where the router is configured to send all packets towards a single router (next hop), by use the dynamic routing protocols we can add information to their routing tables from connected routers automatically. The dynamic protocols are send out topology updates whenever the network changes’ topological structure.
There are many routing protocols available in three subcategories. Proactive [OLSR,DSDV], reactive[AODV,DSR] and hybrid [ZRP,DDR]
The current efficient research process is going on RPL , AODV , LOADng, RPL in Cooja etc. the routing protocols research used to increasing network lifetime.. The area of IoT going to hold most of the future research in the routing protocols will be most useful.
In the another point of view the MPL ( multicasting for low power lossy) is the another one efficient area of research process. And also we can perform the research process in the following area’s, like , Congestion Control, Mobility, and Scalability and Opportunistic routing and also Location privacy
We can perform the routing process in the following networking areas such as
For example, if you choose VANET as your research area, then , during designing the routing protocol, you need to consider the following research issues.
In currently, there are many routing protocols have been Available so far to compete with sudden changes , which is based on the nature of the networks. The following process are the major barriers for routing protocols in networks, like Route discovery, route maintenance and sudden change in the topology.
1. The one of major issue in vanet is, now , the Mobility Bandwidth constraint Error prone shared broadcast radio channel hidden and exposed terminal problems Resource Constraints.
2. The another one issue is ,the Mobility highly dynamic frequent path breaks frequent topology changes.
