/**
 * \file misc_sim.h
 * \brief Functions needed by clients when running inside the simulator
 *
 *  On the semantics of the sim flags.
 *
 *  There are three variables that control the behavior of
 *  the system wrt simulation and emulation.
 *
 *    my_node_id is the node ID for this stack.  It may be
 *      a "real" ID or the ID of a "simulated" stack.
 *
 *    in_sim is a flag that indicates you are part of a
 *      "simulated" stack, i.e. that more than one node
 *      will be running in your group on this machine.
 *      It is true when the SIM_ID env var is set.
 *
 *    my_sim_group is the group number you are in.  It is
 *      a misnomer because it does not imply you are in
 *      simulation mode -- it may mean that you are a
 *      sim component or just that you are using a channel
 *      so as not to collide with other real node traffic.
 *      It will be set to the value of the SIM_GROUP env
 *      variable.

EmStar

EmStar is a software system for developing and deploying wireless sensor networks involving Linux-based platforms. As the wireless sensor network community has attempted to deploy more complex designs---large-scale, long-lived systems that need self-organization and adaptivity---a number of difficult software design issues have arisen. Advances in software design have not kept pace with the capabilities of hardware. This is because designing for an adaptive, efficient, and useful sensor network has turned out to be surprisingly complex and difficult. EmStar is a Linux-based software framework, whose goal is to dramatically reduce this complexity, enabling work to be shared and reused, and simplifying and speeding the design of new sensor network applications.
