| Protocol Objectives and Overview | |
| Performance and Scalability Evaluation | |
| Comparison with On-demand Power Management | |
| Conclusions | |
| Complementing the functionality of existing MANET routing protocols from energy-efficiency perspective | |
| Introducing fair low impact energy conservation to network operation | |
| Achieving robust operation that is independent of the functionality of the routing protocol |
| “Protocol Independent Energy Saving”, PIES | ||
| Achieves fair energy conservation by: | ||
| Putting nodes to sleep for equal time periods. | ||
| Providing the routing algorithm with energy threshold info to help it make fair energy conscious decisions | ||
| Fully distributed algorithm – functionality does not depend on a node or a set of nodes | ||
| Modular nature – easily integrated with existing routing algorithms | ||
| Deterministic sleep pattern enables nodes to determine mathematically neighbors’ sleep state | ||
| Configurable in such a way that introduces no additional traffic to the network | ||
Performance with increased population
Performance with increased traffic
Comparison with the On-demand Power Management - Qualitative evaluation
Comparison with the On-demand Power Management – Energy performance
Comparison with the On-demand Power Management – Effect on Network Lifetime
| Energy is the most scarce resource for the functionality of mobile ad hoc networks | |
| PIES is a solution that achieves fair energy conservation and works with MANET routing algorithms of all categories | |
| Simulations show that PIES scales well with increased network population and traffic | |
| Comparison with on-demand power management showed that PIES has superior energy, network lifetime and data delivery performance |
