Abstract

Due to inherent dynamicity of nodes in Ad-hoc networks, it requires continuous re-broadcasting from one node to another to calculate best route from source to destination. In this paper, we have introduced a novel approach that performs zone based smart re-broadcasting and thereby reduces the flooding of data and energy consumption. Further, this method was combined with location estimation algorithm. Although, Zone-Based Optimal Selective Forwarding (ZBOSF) gives superior results compare to conventional routing protocols but estimated location is not precise. Therefore, to achieve efficient localization and at the same time to keep the energy consumption low we have coalesced DV-distance algorithm for location estimation with ZBOSF. As distance estimations become more correct DV-Distance method provides more accurate position information. Hence, we used Received Signal Strength based DV-distance because of its more accurate distance estimations. Localization with received signal strength (RSS)-based DV-distance not only provides more accurate position information but also eliminates the need for additional hardware.
