In Vivo Evaluation of the Secure Opportunistic Schemes Middleware using a Delay Tolerant Social Network

Over the past decade, online social networks (OSNs) such as Twitter and Facebook have thrived and experienced rapid growth to over 1 billion users. A major evolution would be to leverage the characteristics of OSNs to evaluate the effectiveness of the many routing schemes developed by the research community in real-world scenarios. In this paper, we showcase the Secure Opportunistic Schemes (SOS) middleware which allows different routing schemes to be easily implemented relieving the burden of security and connection establishment. The feasibility of creating a delay tolerant social network is demonstrated by using SOS to power AlleyOop Social, a secure delay tolerant networking research platform that serves as a real-life mobile social networking application for iOS devices. SOS and AlleyOop Social allow users to interact, publish messages, and discover others that share common interests in an intermittent network using Bluetooth, peer-to-peer WiFi, and infrastructure WiFi.Comment: 6 pages, 4 figures, accepted in ICDCS 2017. arXiv admin note: text overlap with arXiv:1702.0565

Reputation-based Energy Efficient Opportunistic Routing for Wireless Sensor Network

Selection of the best next-hop in Opportunistic Routing (OR) is a crucial task in wireless sensor networks (WSN). To increase the throughput, network lifetime and reliability of WSN, there is a need of an optimal OR protocol. To improve the reliability of network, reputation management is important. Reputation management gives a chance to nodes to transmit data on secure and reliable routes. This paper gives a new reputation based OR metric and protocol, in which the next hop selection is based on its reputation. The proposed OR metric considers the reputation level as a primary selection parameter for next-hop. New OR metric relies on energy efficiency and packet delivery ratio of next-hop. Proposed OR protocol selects all middle position neighbors as next-hop and potential forwarder will be decided on the basis of new OR metric. Energy consumption is considered to be dynamic. The protocol has been compared with Middle Position Dynamic Energy Opportunistic Routing (MDOR), and Trust and Location Aware Routing Protocol (TLAR). Simulation results depict that the proposed OR protocol optimized the throughput and network lifetime
