Base-station driven routing protocol for wireless sensor networks

Routing protocols in sensor networks play an important role and have obtained much attention. There are two main routing mechanisms for sensor networks: proactive routing and on-demand routing. As for the disadvantages of energy un-efficiency for the two traditional protocols, and the disadvantages of the mode to trigger the routing, this paper proposed another kind of routing protocol called BS (short for base-station) driven routing protocol, it is special in the way to start routing by the BS-node (the node connected to the base station). And simulation results show that by utilizing this protocol, we spent less time and energy during routing process than the traditional protocols.
