A localization method for mobile sensor networks is presented in this paper. In order to reduce localization errors, the artificial bee colony (ABC) algorithm is used to refine the estimated coordinates. The fundamental concept of the ABC algorithm is to find better feasible solution (food source) from food sources in the specific space. Using the idea, this paper study integrates the ABC algorithm,...
Radio Frequency Identification (RFID) has recently played an important role in wireless sensing network. However, if multiple passive tags are simultaneously transmitted to the reader, the reader is unable to identify the tags. This will reduce the efficiency of a RFID system. To solve this problem, we propose a modified anti-collision algorithm based on ALOHA protocol to improve the performance in...
