摘要：The existing omni directional antenna assisted schemes for localization of sensors in wireless sensor networks (WSNs) are not very accurate due to various constraints, since issues like sensor distribution, topology control; high cost and localization error obstruct the effectiveness of these algorithms and schemes. This paper presents a modified High Resolution Robust Localization (HiRLoc) scheme assisted by a single beam directional antennas for improving the localization in WSNs. Simulation result show that the proposed modified scheme estimates the position of more number of sensor with less average localization error compared to some existing schemes.
