Performance analysis of social-aware content-based opportunistic routing protocol on MANET based on DTN

Abstract

Nowadays, almost all telecommunication devices use TCP/IP to communicate with each other. However, it is difficult for MANET to support the type of end-to-end connectivity required by TCP/IP-based communications due to disruptions, frequent topology changes and network partitions caused by the movement of the nodes. DTN is an emerging paradigm in the telecommunication network which is able to provides data communication in areas with intermittent connectivity, long delay communication, and high error rate. SCORP (Social-aware Content-based Opportunistic Routing Protocol) is a routing protocol on DTN which works by taking account of social proximity and content interests on each node before replicating the message to the other node in order to improve the ability of network in sending messages. In this paper, we show the performance analysis and the advantages of SCORP compared with Epidemic and Spray and Wait under different number of buffer size and nodes on the network. We also show the impact of different number and types of interests per group of nodes on the performance of SCORP. We use Braga and Asia-Afrika area in Bandung as the simulation area in The ONE Simulator.
