Wireless sensor networks have been widely used
in many fields with the developments of the related techniques.
But there are many problems in traditional single sink sensor
networks. The energy of the sensors near the sink or on the
critical paths consumes too fast causing unbalanced energy
consumption. The routing algorithms mainly focus on the
nearest path or minimum hops. The invalidation of the single
sink node causes the breakdown of the whole sensor network.
In this paper, through the analysis of the disadvantages of
single-sink sensor networks, we propose the system
architecture of multi-sink sensor networks and a new routing
algorithm Priority Based Routing (PBR) to balance the energy
consumption of the sensor nodes in multi-sink sensor networks.
Experiment results show PBR has better performances than
traditional methods and prolongs the lifetime of the sensor
