Analysis of location tracking based on friendly points

This paper presented and analyzed a location tracking scheme based on friendly points. A set of friendly points provides with a convenient and accurate location information for mobile tracking. The scheme partitions the target area to reduce the error. The friendly points are selected such that inter distance among the three intersection points is the minimum. The simulation based on the proposed scheme shows some promising output. It reduces the maximal and average errors by 43.25% and 44.59%, respectively. This scheme can be used for wireless sensor network applications where multiple observation facilities are available.
