“…Ranky [9] proposed RFID as one of the most important ten technologies of this century. Li and Becerik-Gerber [10] presented a comparative study of eight indoor positioning sensing technologies taking into consideration the accuracy, power supply, affordability, wireless of the ith particle is updated according to Equations (1) and (2), respectively, until a fixed number of times is iterated or a predetermined minimum error is achieved. (2) where i = 1, 2, · · · , M, M is the number of particles in the population; x i and v i are the position and velocity of the ith particle, respectively; the t + 1 is the index of the current, new, iteration and t refers to the previous, old, iteration; w is a parameter that weighs the inertia of the particle; c 1 and c 2 are the parameters that weigh the cognitive and social constituents, respectively; rand 1 and rand 2 are random numbers which are uniformly distributed within the range [0, 1]; p g is the best position inferred by the swarm considering the experience of all the particles, and p i is the best position visited by the ith particle so far.…”
