Minimal energy consumption in the localization of a sensor network

In this paper we have introduced a new efficient algorithm “Sub-sector Alignment Polar Coordinate Algorithm” (SAPCA) for the localization of a wireless sensor network. There are several different concepts incorporated in the algorithm to make it efficient such as concept of polar coordinates, sub-sectors, pipelining etc. This algorithm is better than the simple layering and the triangulation algorithms as in them there are chances for multiple nodes to get same coordinates and they too require a considerable amount of energy for the localization. The presented algorithm is efficient as it assigns different coordinates to all nodes at low cost i.e. minimal energy consumption and within a minimum amount of time.
