On Tinyos-1.x installation, /opt/tinyos-1.x/tools/make/pc.target defines
NESC_NIDO_TOSNODES ?= 1000
which is then passed on to the compiler as
PFLAGS += -pthread -fnesc-nido-tosnodes=$(NESC_NIDO_TOSNODES)
-fnesc-simulate
so tossim in tinyos-1.x can simulate 1000 nodes. If you are using
tinyos-1.xyou can change it 5000 nodes for your case. I am not sure
about
tinyos-2.x. I would recommend looking at .platform and other make files to
see if a similar option is passed on in tinyos-2.x
