An Improved Algorithm of Virtual Potential Field in Directional Sensor Networks
Jun Huang, Yi Shi, Li Sun, Ru Chuan Wang, Hai Ping Huang · Key engineering materials · 2011
In view of the irrationality that traditional virtual potential field algorithms brought about on the criterion for the generation of virtual force in directional sensor networks, we propose a novel criterion for judgment. Cross-set test is used to determine whether the sensory region has any overlap, thereby restrain the energy cost of nodes and the performance of the algorithm is improved. In simulation experiment, the validity of the novel criterion and IAPD (improved algorithm of virtual potential field in directional sensor networks) are verified by the compare of IAPD and traditional virtual field algorithms.
