+ 
+ Tiny Active Messages ~\cite{hill:j2000} attempt to preserve the
+ basic concepts of integrating communication with computation
+ and matching communication primitives to hardware
+ capabilities. Each message contains the name of a 
+ user-level handler to be invoked on a target node upon arrival 
+ and a data payload to pass in as arguments. The handler function 
+ serves the dual purpose of extracting the message from the network
+ and either integrating the data into the computation
+ or sending a response message. The basic paradigm of typed messages
+ causing handlers to be invoked upon arrival matches up
+ well with the event based programming model supported
+ by TinyOS (the operating system) and demanded by the underlying 
+ sensor hardware. The low overhead associated with event based 
+ notification is complementary to the limited resources of networked
+ sensors. Applications do not need to waste resources
+ while waiting for messages to arrive. Additionally,
+ the overlap of computational work with application
+ level communication is essential. Execution contexts and
+ stack space must never be wasted because applications are
+ blocked, waiting for communication. Essentially, the active
+ messages communication model can be viewed as a
+ distributed eventing model where networked nodes send
+ each other events.
