  In this paper we propose a solution for transmitting digital information
within the cardiocirculatory system. In particular, we make use of a channel
delivering burst of molecules, emitted by mobile transmitters, which diffuse in
the blood towards fixed receivers, that are attached to the vessel walls. This
communication scheme has been inspired by the real signaling between platelets
and endothelial cells, the behavior of which has been investigated
experimentally. We thus believe that our proposal can be successfully deployed
in living bodies. On the basis of the results achieved through simulations on
the communication system capabilities, we propose a simple but effective
receiver scheme, and we outline the future research directions.
