Typical wireless sensor networks consist of sensor nodes and base-stations (sinks). The sensors, sinks, and user nodes can orthogonally provide their own mobility environments. The existing studies take only sensor mobility, sink mobility, and event mobility into account. Inquirer mobility, however, can be possibly suggested as one of the mobility models. An inquirer is one of the existing entity for sensor networks as a user. Inquirer mobility and routing mechanism to support it are proposed in this paper. For that, possible mobility environment and characteristics are also analyzed. At the end of this paper, excellence of the proposed routing model is proved through simulation results.
