In order to improve the service performance of the mobile cloud computing for meter network, handoff strategy of mobile cloud computing was studied, and a new method was proposed based on threshold decision and network selection. This method can be divided into two steps. First, a threshold decision is adopted to decide whether or not to need to be switched. Secondly, multiple attribute decision making method is adopted to select the best alternative network. Experimental results show that the proposed handoff method has better performance than the vertical handoff method and network selection switching method, and the three indexes of the switching frequency, time, and mobile terminal energy consumption are outstanding.
