Abstract
The use of wireless communication in determining the location of a sensor within a sensor network enables a number of
added conveniences. Mobile sensors can use information such as time-of-arrival and wireless signal strength of the received signal to
determine its location relative to the stationary sensors. Using such information within indoor scenarios, as opposed to outdoor
scenarios, becomes more problematic due to the added accuracy requirements. Coding sequences used in the wireless communication
can greatly affect the estimation of location. This paper deals with comparing the use of perfect sequences to the use of mainstream
coding sequences for the purpose of indoor location estimation of wireless sensors. A new approach has been used to show that the use
of perfect sequences delivers accuracy improvement over mainstream solutions.
