Listing 1. Node sleep time basic decision algorithm using ENO

int ENO_algorithm (int Vscap, int Pcell,

int Tsleep max, int Tsleep min)

{

if (Vscap>4.5 V & Pcell >=0.2*Pcell_max)

Tsleep = (eq 22);

else

Tsleep = Tsleep / rho;

if (Tsleep > Tsleep_max)

Tsleep=Tsleep max;

else

if (Tsleep < Tsleep_min)

Tsleep=Tsleep min;

return (Tsleep);

}
