Therefore, this paper optimized the movement direction of the RWP motion model and limits the direction of the node’s motion to an achievable range, which mean the angle between the next motion’s direction and the original motion’s direction should less than the maximum angle that can be achieved, as shown in the Fig. 1 that θ is the maximum value of α. Thus, to limit α to θ range can avoid that the node in the movement of the unreasonable excessive angleBack to article page
