In this paper a hybrid localization scheme for multihop wireless sensor networks is presented. At first a relatively dense group of nodes is selected as a base. Next, the multidimensional scaling (MDS) method is applied to localize the group of nodes. Then, the robust quads (RQ) method is employed to localize other nodes, following which we make use of the robust triangle and radio range (RTRR) approach to perform the localization task. The RQ and the RTRR methods are used alternately until no more nodes can be localized by the two approaches. Simulation results demonstrate that the proposed hybrid localization algorithm performs well in terms of both accuracy and success rate of localization.
