scheduling performed by each elected leader. This two-step process takes
place periodically, in order to choose a small set of nodes remaining active
for sensing during a time slot. Each set is built to ensure coverage at a low
- energy cost, allowing to optimize the network lifetime. %More precisely, a
+ energy cost, allowing to optimize the network lifetime.
+%More precisely, a
%period consists of four phases: (i)~Information Exchange, (ii)~Leader
%Election, (iii)~Decision, and (iv)~Sensing. The decision process, which
- results in an activity scheduling vector, is carried out by a leader node
- through the solving of an integer program.
