On the Practical Issues in Hop Count Localization of Sensors in a Multihop Network

Simple algorithms have been developed in the area of node localization in a wireless sensor network. For these simple algorithms to work, several assumptions were made. However, the accuracy of such assumptions affects the effectiveness and performance of such algorithms. For example, the irregular propagation pattern of transmission range is often neglected in both simulation and analysis. This paper investigates the accuracy of these assumptions and proposes some modifications to improve the hop count localization algorithm in an actual physical implementation
