Sensor Networks - Balancing Energy Use and Quality of Service

Sensor Networks will change the way computers interface with our world and each other.This transformation will be shaped by the network centric paradigm demonstrated in Sensor Networks. Sensor Networks require a data-centric networking paradigm to efficiently and effectively share data. Directed Diffusion is a data-centric networking paradigm which has been established and studied. Energy efficient routing algorithms have been developed, however, these methods can be improved. Routing algorithms to improve these methods are presented here.This paper presents computer simulation results which verify the effectiveness of previously extablishedrouting algorithms and compare them to the new and improved routing algorithms. The results show significant improvement in energy efficiency and resilience.Ultimately, this paper incorporates effective modeling of Sensor Networks to demonstrate the usefulness of these new optimization strategies
