# OPTIMAL ENERGY ALLOCATION FOR DETECTION IN WIRLESS SENSOR NETWORKS

### Krishna Gunturu, Mort Naraghi-Pour

#### Abstract

The problem of binary hypothesis testing in a wireless sensor network is studies in the presence of noisy channels and for non-identical sensors. We have devised an energy allocation scheme for individual sensors in order to optimize a cost function with a constraint on the total network energy. Two cost functions were considered; the probability of error and the J-divergence distance measure. We have also designed a mathematically tractable fusion rule for which optimal energy allocation can be achieved. Results of optimal energy allocation and the resulting probability of error are presented for different sensor network configurations.
