Abstract

In this paper, we present two algorithms for routing in energy-constrained, ad hoc, wireless networks. Nodes running our algorithms can trade off energy dissipation and data delivery quality according to application requirements. Our algorithms work above existing on-demand ad hoc routing protocols, such as AODV and DSR, without modification to the underlying routing protocols. Our major contributions are: algorithms that turn off the radio to reduce energy consumption with the involvement of application-level information, and the additional use of node deployment density to adaptively adjust routing fidelity to extend network lifetime. Algorithm analysis and simulation studies show that our energy-conserving algorithms can consume as little as 50% of the energy of an unmodified ad hoc routing protocol. Moreover, simulations of adaptive fidelity suggest that greater node density can be used to increase network lifetime; in one example a four-fold increase in density doubles network lifetime.
