<p>Energy is the scarcest resource of WSN nodes, and it determines the lifetime of WSNs. WSNs may be deployed in large numbers in various environments, including remote and hostile regions, where ad hoc communications are a key component. For this reason, algorithms and protocols need to address the following issues:</p>

<p>
* Increased lifespan<br/>
* Robustness and fault tolerance<br/>
* Self-configuration</p>
