Abstract: Wireless Sensor Networks (WSNs) is a self-organized network consisting of multiple sensors with limited resources. One fundamental issue in WSNs is deployment of nodes which reflects the networks construct costs, coverage quality, topology and routing etc. As a new technology, dynamic deployment of nodes makes WSN more applicable in many scenes. hhis paper first introduced the self dynamic deployment of nodes with recent valuable theories and algorithms,which are focused on uniform distribution of nodes. And then typical robot assistant deployment strategies were described according to different phases of WSN, which arc aimed at robot movement control and network maintenance.More specifically, advantages and disadvantages of these algorithms were summarized. Finally, key design points and future research directions were put forward.

Key words: Wireless sensor networks, Dynamic deployment, Mobile sensor, Mobile robot
