The integration of ubiquitous wireless sensor network (WSN) and powerful mobile cloud computing (MCC) is a research topic that is attracting growing interest in both academia and industry. In this new paradigm, WSN provides data to the cloud and mobile users request data from the cloud. To support applications involving WSN-MCC integration, which need to reliably offer data that are more useful to...
This paper proposes the idea of a wireless sensor network with applicability in monitoring systems. The goal of the project is to build a monitoring system capable of data gathering which can benefit from both characteristics of fixed and mobile nodes. The flexibility offered by the mobile nodes increases the performance of the entire data acquisition system.
With the increasing popularity of wireless sensor networks in hostile environments it would be desirable to have more reliable ways of delivering collected information to its destination. With a common scenario involving nodes in a sensor network relaying data back to a gateway or router device, which is connected to a backhaul network, the question arises whether this single point of failure could...
In this paper we present an overview of the sensor network architecture as developed in the ANGEL project. We first specify the particular requirements found in healthcare and assisted-living applications, then introduce the general reference architecture and finally discuss some security-related aspects.
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
