| Popis: | 98 Recently, gathering data by collectors is widely discussed. This approach requires that sensors must keep data in their storage until collectors route into their communication range to gather the data. The major concern of collecting data by collectors is to find an efficient routing path for collectors in order to avoid or reduce the data loss caused by long routing time. Most related works have focused on single collector environment, in this thesis we explore how to gather data by multiple collectors in an efficient way. The strategies of collecting data with multiple individual collectors are first proposed and collectors go their separate ways to gather data. Then the routing strategies with multiple cooperative collectors are designed to further reduce the data loss. And we derive the equations of data loss so that the minimum data loss could be computed in order to find the best way of cooperative gathering. The experiment results show that the cooperative routing strategies can significantly reduce the data loss and perform well in any environment. |
