Interior gateway protocol - WikipediaThe Internet of Things IoT is an emerging paradigm that proposes the connection of objects to exchange information in order to reach a common objective. In IoT networks, it is expected that the nodes will exchange data between each other and with external Internet services. However, due to deployment costs, not all the network devices are able to communicate with the Internet directly. Thus, other network nodes should use Internet-connected nodes as a gateway to forward messages to Internet services. Considering the fact that main routing protocols for low-power networks are not able to reach suitable performance in the displayed IoT environment, this work presents an enhancement to the Lightweight On-demand Ad hoc Distance-vector Routing Protocol—Next Generation LOADng for IoT scenarios.
Routing Protocol Basics
Interior gateway protocol
RIP Routing Information Protocol is a forceful protocol type used in local area network and wide area network. RIP Routing Information Protocol type is categorized interior gateway protocol within the use of distance vector algorithm. Routing information protocols defined in It also has version 2 and nowadays both versions are in use. Router used it to exchange routing data within an independent system. Interior gateway routing protocol created in part to defeat the confines of RIP Routing Information Protocol in large networks. It maintains multiple metrics for each route as well as reliability, MTU, delay load, and bandwidth.
An interior gateway protocol IGP is a type of protocol used for exchanging routing information between gateways commonly routers within an autonomous system for example, a system of corporate local area networks. This routing information can then be used to route network-layer protocols like IP. Interior gateway protocols can be divided into two categories: distance-vector routing protocols and link-state routing protocols. By contrast, exterior gateway protocols are used to exchange routing information between autonomous systems and rely on IGPs to resolve routes within an autonomous system. Distance-vector routing protocols use the Bellman—Ford algorithm. In these protocols, each router does not possess information about the full network topology. It advertises its distance value DV calculated to other routers and receives similar advertisements from other routers unless changes are done in local network or by neighbours routers.

All of this is done with running examples and illustrations to clarify concepts and enhance the enjoyment of networking. While OSPF has traditionally been an organizational networking protocol, in these exciting times of Software Defined Networking SDN , it has assumed an important role in the consolidated data center too. Now that the traditional distinctions between server and network roles are getting blurred, everyone in the data center needs to become familiar with networking and networking protocols!

Routing Information Protocol RIP is a dynamic routing protocol which uses hop count as a routing metric to find the best path between the source and the destination network. It is a distance vector routing protocol which has AD value and works on the application layer of OSI model. RIP uses port number Hop Count : Hop count is the number of routers occurring in between the source and destination network. The path with the lowest hop count is considered as the best route to reach a network and therefore placed in the routing table.
