Abstract:

A location assisted energy optimal routing (LAEOR) algorithm was proposed for deep space backbone network based on the theoretical analysis for the energy routing over deep space backbone network. LAEOR not only takes into consideration of the equipment constraints and energy restriction, but also makes use of the node location information. It introduces a threshold value to design and optimize routing strategy. Simulations demonstrate that this algorithm can decrease and balance energy consumption, and reduce both transmit time and the packet dropped rate.
