The performance evaluation of heuristic information-based wireless sensor network routing method

초록

With recent technological advance, wireless sensor networks are often used in data collection and surveillance. One of the objectives of research on routing methods in wireless sensor networks is maximizing the energy life of sensor nodes that have limited energy. Among basic routing methods, the method using location information is efficient because it requires less information for calculation in route setting than flat routing and hierarchical routing. Because it utilizes distance, however, sensor nodes' energy utility may go down. In this study, we tried to even energy use in a wireless sensor network by giving a weight to the transition probability of ACS(Ant Colony System), which is commonly used to find the optimal path, based on the amount of energy in a sensor and the distance of the sensor from the sink. The proposed method showed improvement by 46.80% on the average in energy utility in comparison with representative routing method GPSR (Greedy Perimeter Stateless Routing), and its residual energy after operation for a specific length of time was 6.7% more on the average than that in ACS © 2011 Springer-Verlag.
