Abstract

Data replication is an indispensable service for mobile ad hoc networks and it helps to increase data availability, reduce communication overhead, achieve fault-tolerance and load balancing. Our scalable and reactive data replication framework SCALAR operates in a peer-to-peer manner where the network nodes construct a connected dominating set based on the topology graph, and use that virtual backbone for efficient data lookup and replication. In this study, we compare the performance of SCALAR with the well-known SAF and DAFN replication approaches on realistic application scenarios simulating university campus and shopping mail settings. We examine data accessibility, protocol overhead, effects of data request probability and percentage of popular data items in the system through extensive runs conducted on SWANS simulator. SCALAR is shown to outperform the other approaches in terms of data accessibility and overhead, and demonstrated as an efficient and scalable replication solution for mobile ad hoc applications.

Replication (computing)

Replication in computing involves sharing information so as to ensure consistency between redundant resources, such as software or hardware components, to improve reliability, fault-tolerance, or accessibility. Replication in computing can refer to: Data replication, where the same data is stored on multiple storage devices Computation replication, where the same computing task is executed many times.

Wireless ad hoc network

A wireless ad hoc network (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes. The determination of which nodes forward data is made dynamically on the basis of network connectivity and the routing algorithm in use.

Internet backbone

The Internet backbone may be defined by the principal data routes between large, strategically interconnected computer networks and core routers of the Internet. These data routes are hosted by commercial, government, academic and other high-capacity network centers, as well as the Internet exchange points and network access points, that exchange Internet traffic between the countries, continents, and across the oceans.
