P-ICSGD: Positive Iterative Calculation of Secondary Grid Division Localization Scheme in Wireless Sensor Networks
Localization scheme is quite critical for Wireless Sensor Networks (WSNs). Iterative Calculation of Secondary Grid Division (ICSGD) localization scheme could solve the inconsistency between calculation amount and location accuracy. ICSGO localization scheme could be divided into two categories, positive iterative calculation of secondary grid division (PICSGD) and negative iterative calculation of secondary grid division (N-ICSGD) according to division ways. This paper compared the performance of P-ICSGD localization scheme with that of N-ICSGD localization scheme. Simulation showed that the average location error of P-ICSGD localization scheme could decrease by 57.6％ than that of N-ICSGD localization scheme when calculation amount was equal.
