In the recent past, we witnessed to a dramatic growth of networks with a huge number of interconnected wireless nodes exchanging large amounts of information. This has brought to the need of ad-hoc, energy-aware protocols suitable for low-power and lossy networks. Among these, Routing Protocol for Low Power and Lossy Networks (RPL) is surely one of the most interesting ones. It chooses the optimal...
US water utilities are faced with mounting operational and maintenance costs as a result of aging pipeline infrastructures. Leaks and ruptures in water supply pipelines and blockages and overflow events in sewer collectors cost millions of dollars a year, and monitoring and repairing this underground infrastructure presents a severe challenge. In this paper, we discuss how wireless sensor networks...
This demonstration presents the results of a study addressing an issue that has constrained the effectiveness of wireless sensor network deployments to date, namely, connectivity. A physically compact, diversity antenna has been developed that is low in complexity and therefore suitably controlled using resource-limited wireless sensor hardware. Herein, this prototype antenna is demonstrated utilizing...
