ItemMagicWeaver: An Agent-Based Simulation Framework for Wireless Sensor Networks(2002-08-01) Tolia, Sovrin; Finin, Tim; Joshi, AnupamDistributed sensor networks have been the focus of considerable research during the past few years. Current research on wireless sensor networks can involve a number of issues, including hardware constraints, communication and routing issues, data management problems, and software engineering principles. To clearly understand their characteristics, we require development environments to design them, explore architectural alternatives, and simulate their performance. MagicWeaver is an agent-based simulation framework for wireless sensor networks. It provides abstract models for sensor tasking and communication, device constraints, network topologies and the physical environment. It also supports a special class of applications characterized by streaming data-feeds. MagicWeaver illustrates ways in which agents paradigm extends it`s flexibility to incorporate teamwork and coordination between sensor agents. In this paper we discuss MagicWeaver`s underlying design rationale and provide it`s current implementation status. We also report on results obtained while performing scalability tests using the JADE agent platform. ItemSecurity for Wireless Sensor Networks(Springer Nature Switzerland AG., 2004-01-01) Avancha, Sasikanth; Undercoffer, Jeffrey; Joshi, Anupam; Pinkston, JohnThis chapter identifies the vulnerabilities associated with the operational paradigms currently employed by Wireless Sensor Networks. A survey of current WSN security research is presented. The security issues of Mobile Ad-Hoc Networks and infrastructure supported wireless networks are briefly compared and contrasted to the security concerns of Wireless Sensor Networks. A framework for implementing security in WSNs, which identifies the security measures necessary to mitigate the identified vulnerabilities is defined.
