Citation Count: 0

Existing workflow management systems execute complex sequences of tasks by invoking corresponding services identified at execution time and ordered according to a graph that captures the workflow execution rules and data dependencies. The technology is mature and is used across the Internet to support a wide range of business transactions ...

Recent years have seen the emergence of wireless cyber-physical systems that must support real-time queries of physical environments through wireless sensor networks. This paper proposes Real-Time Query Scheduling (RTQS), a novel approach to conflict-free transmission scheduling for real-time queries in wireless sensor networks. First, we show that there is an ...

Energy constraints and high connectivity dynamics render Wireless Sensor Networks (WSNs) difficult to program and use. Software applications must be coordinated not only functionally, as is traditionally done, but also in terms of resource utilization and adaptation to a dynamic environment. This paper presents Adaptive Servilla, a middleware that provides ...

Device heterogeneity in wireless sensor networks is rendering such networks increasingly difficult to program. To address this problem, we present Servilla, a novel middleware that enables applications to be both platform-independent and efficient despite executing over a diverse and dynamic set of devices. It achieves this by using service-oriented computing ...

As wireless sensor networks become increasingly integrated with the Internet, the Internet of Things (IOT) is beginning to emerge. The IOT is a massive cyber-physical system that presents many software engineering challenges. One fundamental challenge is the need for multi-dimensional QoS that can satisfy the individual constraints of the many ...

With the emergence of high data rate sensor network applications, there is an increasing demand for high-performance query services. To meet this challenge, we propose Dynamic Conflict-free Query Scheduling (DCQS), a novel scheduling technique for queries in wireless sensor networks. In contrast to earlier TDMA protocols designed for general-purpose workloads, ...

Wireless sensor networks (WSNs) exhibit high levels of network dynamics and consist of devices with limited energy. This results in the need to coordinate applications not only at the functional level, as is traditionally done, but also in terms of resource utilization. In this paper, we present a middleware that ...

Queries are convenient abstractions for the discovery of information and services, as they offer content-based information access. In distributed settings, query semantics are well-defined, for example, queries are often designed to satisfy ACID transactional properties. When query processing is introduced in a dynamic network setting, achieving transactional semantics becomes complex ...

The robust operation of many sensor network applications depends on deploying relays to ensure wireless coverage. Radio mapping aims to predict network coverage based on a small number of link measurements. This problem is particularly challenging in complex indoor environments where walls significantly affect radio signal propagation. Nevertheless, we show ...

Wireless sensor networks are evolving from dedicated application-specific platforms to integrated infrastructure shared by multiple applications. Shared sensor networks offer inherent advantages in terms of flexibility and cost since they allow dynamic resource sharing and allocation among multiple applications. Such shared systems face the critical need for allocation of nodes ...

Pervasive computing applications often entail continuous monitoring tasks, issuing persistent queries that return continuously updated views of the operational environment. We present PAQ, a middleware that supports applications' needs by approximating a persistent query as a sequence of one-time queries.

The practice of using workflows to model complex activities in stable networks is commonplace and is supported by many commercially available workflow management systems (WfMSs). However, the use of workflows to model collaborative activities in mobile environments, while possible at the model level, has not gained traction due to the ...
