Study on performance evaluation method based on measurement for wireless sensor network

Due to non-uniform network architectures and different kinds of performance requirements in different applications, a universal method of performance evaluation for wireless sensor network is still lacking at present. The new performance evaluation criteria system for wireless sensor network are defined in this paper, such as residual energy, network lifetime and coverage degree. And a synthetic multi-criteria performance evaluation method based on criteria weight is put forward, with the integration of mathematical modeling and measurement approach. Regarded the path as a basic performance evaluation unit, a multiple measurement criteria matrix is established to calculate a synthetic performance value of the path, in which the criteria weight can be set according to the different applications. The simulation results show that network performance of wireless sensor network can be achieved efficiently with our method, in which differences in applications can be shielded. And the method can be applied to all kinds of wireless sensor networks.
