Cloud computing based routing protocol for infrastructure-based opportunistic networks

摘要

In Opportunistic Networks (Oppnets), a permanent fixed path is never assumed to be available between the source and destination. Nodes are not aware of changing network topology. So, static routing is not possible here and dynamic routing is best suited for such networks. In this paper, a Cloud Computing Based Routing Protocol (CCBRP) has been proposed for infrastructure-based Oppnets. It uses the concept of cloud computing in which data and other utilities can be accessed, configured, and manipulated on demand. In this work, 3-tier architecture has been developed for CCBRP that has three layers namely normal/regular nodes, Infostation infrastructure, and Cloud server architecture. The performance of CCBRP is evaluated and compared against the Horizontal and Vertical Ferry (HVF) strategy. Results obtained indicate that CCBRP outperforms HVF in respect of average latency and messages delivered.
