Federating Disjoint Wireless Sensor Networks


Wireless sensor networks (WSN) can increase the efficiency of many real-life applications through the collaboration of hundreds of miniaturized sensors which can be deployed unattended in harsh and inhospitable environments. While such deployment eliminates/reduces human intervention and provides fully-automated data gathering systems, WSNs are still prone to sensors failure which not only can degrade the quality of coverage but also disrupt the data traffic. To address such a problem, most approaches in the literature deploy redundant nodes during network setup and reconfigure the network topology to establish alternate data paths. However, sometimes the network suffers a large scale damage involving many nodes and gets partitioned into multiple disjoint segments. For these cases, a provisioned approach for tolerating occasional failures at the network design level will not be effective. A similar scenario is when an application can be leveraged by engaging a number
of standalone WSNs. For example, the disaster response may involve collaboration among multiple government agencies and may need to combine the services of their autonomously-operating WSNs in the search-and-rescue process. The main goal of the proposed research is to quickly repair a structurally damaged WSN or linking multiple disjoint WSNs with the least resources and overhead. This process is called a federation. Federation of multiple network segments is characterized as short lived and rapid in order to ensure responsiveness to application needs until a more stable solution is developed or the need for combining the network services ends. This project is collaboration of University of Maryland Baltimore County and Southern Illinois University Carbondale.
