Energy aware dynamic task allocation in mobile ad hoc networks

Dynamic task scheduling has been intensively studied over the last several years. However, since the emergence of mobile computing, there is a need to study dynamic scheduling in the environment of mobile ad hoc networks, which contain a group of heterogeneous mobile nodes powered by batteries. For such a time-energy efficient system, performance evaluation using only a time metric is not enough. In this paper, we propose a novel energy aware dynamic task allocation (EADTA) algorithm with a goal of time-energy efficiency, to minimize the average per task delay and energy consumption. We evaluate the algorithm under different scenarios and conduct a simulation to analyze its behavior. Results demonstrate that EADTA is superior to traditional algorithms in both the time and energy metrics.
