The aim of this paper is to put forward a novel measurement of uncertain information to dispose of multiple attribute group decision making (MAGDM) based on interval type-2 cross-entropy. Firstly, some basic concepts and a ranking value formula to calculate the ranking value of interval type-2 fuzzy sets (IT2FSs) is briefly introduced. Meanwhile, a novel measurement based on interval type-2 cross-entropy to measure the uncertainty of the IT2FSs is investigated, the advantage of measurment can be interpreted as it not only considers the uncertainty of the element itself, but also considers the uncertainty caused by other elements. By using the measurement which has proposed, a method was presented to determine attribute weights based on the principle of minimization. Moreover, a decision making procedure based on measurement value is given to select the best alternative(s). Lastly, we apply the proposed decision making procedure based on measurement value to a simple practical example, which can illustrate the practicality and effectiveness.

With the expansion of the scale of wireless sensor network (WSN), the network node number is increasing. Because of the huge network overhead and low precision, the reference broadcast time synchronization algorithm can not meet the actual demand. In this paper, a novel time synchronization algorithm for high precision energy efficient wireless sensor networks is proposed. Through a Markov random field-based maximum a posteriori estimation method of wireless sensor network in two nonadjacent nodes in receiving multiple reference broadcast messages, the algorithm estimated the clock drift under the condition of phase error estimation, tracked in real time by the Gardner loop, and then realized the time synchronization process. Finally, the MATlab.simulation showed the proposed algorithm not only has a further improvement in the time synchronization accuracy, but also effectively reduces the overall energy consumption level of the whole WSN.

In this paper, we focus our attention on the issue of MAGDM under interval type-2 fuzzy environment where all the information provided by the decision makers is characterized by IT2FSs and the information about the attribute weights are partly known and completely unknown. Firstly, some basic concepts are introduced. Then, a new definition of the cross entropy which consider three aspects of fuzziness, hesitancy and interval information is given. Interval type-2 fuzzy entropy is proposed on the basis of the cross entropy. Furthermore, two ranking-entropy optimal models of each alternative are built. A new approach to multiple attribute group decision making with IT2FSs based on interval type-2 fuzzy cross-entropy and ranking value is shown. Finally, we give a practical example to verify the feasibility of our method and make some comparisons with other previous methods. The results verify the validity and effectiveness of our proposed method.
