DISCRETE EVENT MODELING AND SIMULATION OF A MODIFIED DYNAMIC EN-ROUTE FILTERING TO IMPROVE THE ENERGY EFFICIENCY IN WIRELESS SENSOR NETWORKS.

Because wireless sensor networks are exposed to various attacks, security protocols are essential. Among the representative attacks and countermeasures, there are a false report injection attacks and a dynamic en-route filtering scheme. Dynamic en-route filtering scheme effectively defends using message authentication code, but there is room for improvement in terms of energy. So, we use a key re-distribution algorithm of dynamic en-route filtering to improve energy efficiency. In this paper, we propose a discrete event modeling and simulation of modified dynamic en-route filtering. More accurate measurement is possible through the same system designed as the actual wireless sensor network. The experimental results demonstrate the validity of our scheme, showing an energy efficiency of up to 42.45% and a filtering capacity of up to 18.71% compared to the existing scheme.
