A wireless push-type network simulator that considers locality of demand for performance improvement. The network environment consists of multiple directed emitters for parallel data broadcasting. Performance depends on the mean response time of clients.

This project contains an infrastructure for visual simulation of wireless sensor networks, which allows evaluate the energy consumption of the network when running reactive applications whose load is described by stochastic models. Besides of the performance evaluation of different network configurations, it also provides resources for evaluating dynamic network management strategies. Through experiments, the effectiveness of the framework is demonstrated to evaluate network performance considering more realistic load models as well as to evaluate strategies for load balancing.

While wireless sensor networks are increasingly equipped to handle more complex functions, in-network processing may require these battery powered sensors to judiciously use their constrained energy to prolong the effective network life time especially in a heterogeneous settings. Clustered techniques have since been employed to optimize energy consumption in this energy constrained wireless sensor networks.

...We propose a deterministic energy-efficient clustering protocol that is dynamic, distributive, self-organizing and more energy efficient than the existing protocols. It utilizes a simplified approach which minimizes computational overhead-cost to self-organize the sensor network. Our simulation result shows a better performance with respect to energy consumption, which is reflected in the network lifetime in both homogeneous and heterogeneous settings when compared with the existing protocols. It is worthy of note that our approach approximates an ideal solution for balanced energy consumption in hierarchical wireless sensor networks.

Liowsn (Linux for works with WSN) was created to assist teachers, students and people involved with projects of Wireless Sensor Network (WSN). The operating system is Ubuntu 9.10 remastered and it contains several tools for simulation and testing installed to work with WSN.

WSNWARE is an open source Java/OSGi middleware, designed for monitoring, controlling and standardizing Wireless Sensor Network. WSNWARE is a normalized message oriented middleware running on (and developed for) any OSGi containers.

Titan allows service-oriented processing of context recognition applications on Wireless Sensor Networks. It includes an execution environment developed for TinyOS and a Java ME (Personal Profile) Network Manager intended to be run on a mobile phone.

MEM Net - Mote EMulator Network. This project will focus on: 1) MEM - Wireless Sensor Node (mote) emulator 2) MEM Net - network of emulated motes So far, the only released package is “visual-sim-slides”. More comming next !

TOPO is a simple tool that allows the user to create and manipulate arbitrary Wireless Sensor Network (WSN) topologies without worrying about the anomalies that could arise using a text-base topology description. It is fast and easy to use and can accelerate small scale projects such as network simulation. The tool is still undergoing development stage and is open to extension. One the candidate component to be soon integrated is a WSN discrete event simulator.
