It is a key problem to the passive routing that how to evenly use the energy of sensor nodes while decreasing
time-delay of sensing data. The paper considers demands of both rapid data transmission and balanced energy consumption.
Especially for the process characteristic event, an energy-balanced and multi-path aggregated routing algorithm(EB-MPA)
is proposed. Based on the network layer graph, the algorithm can select regional center node, which decreases transmission
delay when source node communicates with the base-station via multi-hops. In addition, EB-MPA introduces the metric of
energy consumption cost as guide line for node determining each hop. Since nodes possess the capability of data aggregation,
the energy level of network can be decreased.
