neighboring hosts that a platform can place its child platform on, it places the child
on a host whose health ratio is highest among others.
The behavior policy of platform death includes the following two factors:
1. Energy level: Platform energy level. Platforms die when they run out of their
energy.
2. Energy loss rate: The rate of energy loss, calculated with Equation 19.2.
Platforms die in response to sharp drops in demands for their resources.
Each agent/platform expends energy to invoke behaviors (i.e., behavior invoca-
tion cost) except the death behavior. When the energy level of an agent/platform
exceeds the cost ...
