Performance Evaluation of Routing Protocols In Hybrid Network

In Mobile Ad hoc Network (MANET) the mobile devices are able to move independently by configuring themselves in the network. The topology is not fixed in MANETs. To increase the coverage area and to access the existing services, MANETs are combined with different networks such as internet to form a hybrid network. To combine different networks, devices such as Gateways are required. For the connection of mobile nodes with internet, those mobile nodes must first find and register with the gateways using gateway discovery mechanism. In our paper, we are using the concept of Dynamic gateways. We are experimenting with several parameters to select gateway out of multiple gateways. In our paper we have proposed a load balancing algorithm which addresses this issue. Our algorithm outperforms when compared with existing algorithms by balancing the load among gateways. We have compared DSDV and DSR with our proposed method which uses AODV routing protocol with additional parameters. The parameters used for the performance analysis of our algorithm are Packet delivery ratio, throughput and Average end-to-end delay.
