Em: A Software Environment for Developing and Deploying Wireless Sensor Networks

Free registration required

Executive Summary

Em is a software environment for developing and deploying Wireless Sensor Network (WSN) applications on Linux-class hardware platforms (called "Microservers"). Em consists of libraries that implement message-passing IPC primitives, tools that support simulation, emulation, and visualization of live systems, both real and simulated, and services that support for networking, sensing, and time synchronization. While Em's design has favored ease of use and modularity over efficiency, the resulting increase in overhead has not been an impediment to any of the authors' current projects.
