Abstract EN
Navigation with wireless sensor networks (WSNs) is the key to provide an effective path for the mobile node.
Without any location information, the path planning algorithm generates a big challenge.
Many algorithms provided efficient paths based on tracking sensor nodes which forms a competitive method.
However, most previous works have overlooked the distance cost of the path.
In this paper, the problem is how to obtain a path with minimum distance cost and effectively organize the network to ensure the availability of this path.
We first present a distributed algorithm to construct a path planning infrastructure by uniting the neighbors’ information of each sensor node into an improved connected dominating set.
Then, a path planning algorithm is proposed which could produce a path with its length at most c times the shortest Euclidean length from initial position to destination.
We prove that the distributed algorithm has low time and message complexity and c is no more than a constant.
Under different deployed environments, extensive simulations evaluate the effectiveness of our work.
The results show that factor c is within the upper bound proved in this paper and our distributed algorithm achieves a smaller infrastructure size.
