WIRELESS SENSOR NETWORK CHARGING METHOD FOR MULTI-CHARGE NODES

摘要

A wireless sensor network sensor network charging method for multi-charge nodes, including the following steps: (1) establishing a WSNs model; (2) dividing field ranges of charging trolleys; and (3) charging the charging trolleys: (a) initializing: l=0 and j=0, wherein l is the total number of received alarm nodes, and j is the serial number of an alarmed node; (b) receiving an alarm signal, updating values of l and j, generating a shortest charging path s_l, and computing an energy discriminate vector; (c) if a vector element satisfies Q_lj≦5% B and j=1, 2, . . . , l, then executing a charging task on l alarm nodes according to the shortest charging path s_l corresponded thereby, otherwise, returning to continuously update the values of l and j; (d) executing the charging task; and (e) determining whether the charging trolleys are required to go back to a parking lot for recharging, enabling the charging trolleys to go back to the parking lot for recharging if yes, and otherwise, returning to continuously update the values of l and j and the vector element Q_lj.
