Measuring Energy-Time Efficiency of Protocol Performance in Mobile Ad Hoc Networks

摘要

This paper introduces two new metrics for assessment of mobile ad hoc network performance in terms of energy-time efficiency. The combined effect of both energy and time consumption is considered and represented in mathematical terms. The measures have demonstrated a number of advantages over the conventional ones in which the energy and time were often considered separately. The proposed new metrics are simple, generic and flexible. As an application, we have compared the energy-time efficiency of Blocking Expanding Ring Search (BERS) and Expanding Ring Search (ERS), two similar Time to Live (TTL)-based expanding ring search algorithms using our new metrics. The results show that the new metrics can be applied efficiently in assessment of different protocols.
