This paper focuses on analysis of the power consumption of wireless sensor nodes with heterogeneous multi-sensors. The power consumption is investigated in three sensor access modes: serial access mode, parallel convert mode, and event driven mode. The mathematic models of the power consumption in these sensor access modes are established and evaluated in the paper. In terms of the solutions of wireless sensor nodes provided by Crossbow and Jennie, etc., a general framework of a wireless sensor node is proposed as well. The work can be used to guide the design of control system of a wireless sensor node.
