As to the deficiency of classic MDS-MAP algorithm from the perspective of positioning accuracy and matrix complexity, this paper proposes a distributed MDS for WSNs. This algorithm uses the method of distance quantification to obtain the close-neighbor vector (CNV), then calculates the distance matrix D, and gets the initial value of nodes locations through the distributed algorithm, finally, uses...
Wireless sensor networks (WSNs) are composed by battery supplied nodes. Node lifetime is defined as the time when the node works properly, before battery depletion. Distances between nodes determine the required radio output power level to ensure reliable connectivity among them, affecting then the node battery current consumption. If some node runs out, it could make unreliable network function....
