Integrated Evaluation on Effectiveness of ULP-DDNS Networking Layer

摘要

This paper describes the up-to-date results got through Ultra Low-Power Data-Driven Networking System (ULPDDNS) project mainly about the network portion. The ULPDDNS has been aiming at achieving reduction of power consumption to 1/100 - 1/1000 compared with the existing systems. We have been tackling with the networks applicable to the emergency situation such as natural disaster. In the emergency case, the need of low power consumption systems and networks are really essential due to lack of power infrastructure. We believe the most applicable network to disaster situation is Mobile Ad hoc NETwork (MANET). This paper shows the evaluation results on the ULPDDNS networking layer activities on MANET by integrating three techniques to establish highly efficient and energy saving MANETs with reasonable performance: (1) GPS-aided target information discovery, (2) Load-aware broadcast-type contents delivery, and (3) Trust relationship list based key management.
