# Performance Analysis of Mesh Based Enterprise Network Using RIP, EIGRP and OSPF Routing Protocols +
## 1 Introduction  
Today communication based on the Internet has become an integral element of daily life. Consequently, the development of computer networks based on IP routing protocols also plays a significant role in any enterprise network. In small areas of a wireless sensor network, the sensor node and base stations are so close to each other and share information directly with one another with low latency [1]. This type of communication system is known as a single-hop communication system. However, in wireless sensor networks, the coverage area is massive, and to cover these large areas need many sensor nodes. Multi-hop communication (indirect connection) is required in this case because most of the sensor nodes are locating so far away from the sensor nodes that they cannot connect directly with the base station [2]. Within a multi-hop network connection, the sensor nodes not only generate and transmit data but also provide a route for other sensor nodes to communicate with the destination base station node. Finding an appropriate route from a source node to a destination node is referred to as routing, and it is the key responsibility of the routing protocol [3]. Routing protocols describe how routers interact with another router, executethis task and identify the optimal paths for transferring data from one node to another. Data transmitted over the Internet should be routed between networks using routing algorithms [4; 5; 6]. The routing algorithms depend on different parameters for selecting the most suitable path for transmitting information over the Internet (i.e., bandwidth, cost, packet delay, hop count and maximum transmission unit). The significant benefit of adopting a dynamic routing protocol allows routers to learn about new networks when changes in the network topology and discover alternative routes if a link fails in an existing network [7; 8; 9; 10]. Currently, many organizations are shifting towards their previous network topology (such as RIP) to more current network topology by upgrading routing protocols mechanisms (such as EIGRP and OSPF) [11; 12; 13]. This research aims to identify the optimal routing protocol topology for each routing protocol since each routing protocol has unique characteristics. Routing protocols define how routers acquire network topology information. Identifying the route should be accomplished using a package router function that analyzes all possible routes to the destination and determines the most optimum [14; 15; 16]. Each routing protocol facilitates the exchange of network information between participating routers. However, some protocols only convey information about direct connections. There are also variations in speed and scalability across protocols [17; 18; 19; 20].  
This research will compare the performance of several inner gateway dynamic routing protocols, including RIPv2, EIGRP and OSPF, using Cisco packet tracer software. In addition, to demonstrate how to transfer data across various networks running different routing protocols using route redistribution systems in packet tracer simulation software. Each of these dynamic routing protocols has its own set of advantages and disadvantages; for example, one protocol has rapid convergence, while another has high reliability. However, the dynamic routing is all improved in general scalability, robustness and convergence.  
This work has three parts. First, a theoretical analysis of the three routing methods will be presented. Second, we will look at how to create and execute a standard model for testing routing protocols. The simulation was performed using a CISCO PACKET TRACER network simulation tool. Finally, we will look at some of the outcomes and check our conclusions about them.
