Modified Improved Alternating Combination Trilateration Algorithm with a Variable m
In most applications of wireless sensor network, the acquired information is useful only when their locations are known. Compared with ACT (alternating combination trilateration), IACT (improved alternating combination trilateration) has reduced its calculation overhead greatly. In IACT, The value of m, which determines how many triangles are used in calculations, is static. In this paper, the value of m is studied further, and a modified improved alternating combination trilateration is proposed. The simulation results show that its calculation can be reduced further when m is defined according to the number of anchor nodes.
