| Popis: | 96 This thesis discusses on how to let the vulnerable area in the network will not be affected by the sensor node''s sensing ability as the weakest path of the network in wireless sensor networks. This paper addresses by moving sensor nodes to change the vulnerable path in the network so that it does not cross the vulnerable area in the network, hence it achieves the purpose of defense. In order to avoid excessive consumption of electricity to the sensor nodes, the algorithms which this paper proposed only deals with moving a small number of paths to the sensor nodes, then by using the sensor node''s sensing ability it then can detect the weakest path. The simulation results shows that the proposed VAPM algorithm can reduce the total energy consumption for changing the vulnerable path, and the energy consumption will not affected by network density and the radius of the vulnerable area. |
