As the technology of wireless networks become increasingly matured and supported by small, micro-mobile devices fully, wireless sensor network has gradually become a research hotspot. The paper deals with the working of wireless sensor network. In which it compare the different working of wireless sensor network. Basically there are two types of wireless sensor network, traditional sensor network and the hierarchical sensor network. Traditional sensor network is the already available network which uses more battery. But hierarchical sensor network introduces two level of nodes i.e., low end and high end. This will increase the overall lifetime of network. After considerable research it is found out that performance of hierarchical network is more than traditional and it increases the lifetime of network.
