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.
