Abstract: A suitable routing algorithm is an important guarantee for the wireless sensor network to display function. In this paper, a routing scheme for the temperature monitoring platform based on wireless sensor network is preliminarily studied. After analyzing and comparing the current routing protocols, the directed diffusion protocol is proposed and the process of directed diffusion is illustrated. Aiming at the concrete application to temperature monitoring platform, the corresponding algorithm design is carried on. Thus, the
advantages and disadvantages of directed diffusion protocol are summarized for this application.
