Wiselib: A Generic Algorithm Library for Heterogeneous Sensor Networks

Abstract

Abstract.One unfortunate consequence of the success story of wireless sensor networks (WSNs) in separate research communities is an evergrowing gap between theory and practice. Even though there is a increasing number of algorithmic methods for WSNs, the vast majority has never been tried in practice; conversely, many practical challenges are still awaiting efficient algorithmic solutions. The main cause for this discrepancy is the fact that programming sensor nodes still happens at a very technical level. We remedy the situation by introducing Wiselib, our algorithm library that allows for simple implementations of algorithms onto a large variety of hardware and software. This is achieved by employing advanced C++ techniques such as templates and inline functions, allowing to write generic code that is resolved and bound at compile time, resulting in virtually no memory or computation overhead at run time.The Wiselib runs on different host operating systems, such as Contiki, iSense OS, and ScatterWeb. Furthermore, it runs on virtual nodes simulated by Shawn. For any algorithm, the Wiselib provides data structures that suit the specific properties of the target platform. Algorithm code does not contain any platform-specific specializations, allowing a single implementation to run natively on heterogeneous networks.In this paper, we describe the building blocks of the Wiselib, and analyze the overhead. We demonstrate the effectiveness of our approach by showing how routing algorithms can be implemented. We also report on results from experiments with real sensor-node hardware.

Dynamic resource aware sensor networks: Integration of sensor cloud and ERPs

“…It means that in our proposed application level architecture, most of the information required for sensors' reconfiguration will be provided by processing sensors' data in ERPs and existing high level information about sensors' area. Sensors' interface is not exposed to users like ERPs through web services in our design to avoid any resources mismanagement or security issues [1]. In the proposed design, with distributed decision making applications and ERPs we generate some useful in- Figure 2.…”

Distributed algorithm engineering for networks of tiny artifacts

“…Another way is offered by the Wiselib [20]. It addresses all of the above issues in a standard, algorithmist-friendly way.…”

“…Users can freely configure a virtual topology on top of the physical topology by configuring so-called virtual-links [19] between nodes located in different testbeds. To master the heterogeneity during application development WISEBED provides a hardware-independent, generic algorithms library (the Wiselib, [20]) allowing one to write code that is resolved and bound at compile time, resulting in virtually no memory or computation overhead at run time.…”

Demo Abstract: Bridging the Gap between Simulated Sensor Nodes and the Real World

“…Application code can be developed using the Wiselib [2], a platform independent C++ algorithm library for heterogeneous sensor networks. Applications using the Wiselib can be compiled for several platforms such as iSense, Contiki, or even simulators.…”
