Abstract
In many localization applications, the exact locations of randomly distributed sensor nodes are essentially required with a precise accuracy in a wireless sensor network. Different placement scenarios of master nodes play a major role in a sensing area for effective network wide localization. In this paper, Time Difference of Arrival with Dual Velocity (TDOA-DV) localization technique is employed along with the proposed Broadcast Sub-anchoring Packet (BSP) technique for the effective localization of several sensor nodes over a network. This new technique investigates the effect of different placements of three master nodes over a network wide. From the simulation results, it can be observed that localization error limit of 0.002m can be achieved over a network wide with the placement of anchor nodes.
