A key problem in re search on Wireless Sensor Networks (WSNs) is how to improve efficiency and extend the lifetime of energy sensor nodes and therefore the WSNs. In this paper, we address this problem and present a geography-based heterogeneous hierarchy routing (GBHHR) protocol. GBHHR adopts hierarchy structure for, better data congregation efficiency of data which can improve the collection and uses heterogeneous nodes as cluster heads to solve the problem of selecting cluster head in traditional hierarchy routing algorithms. A dormancy mechanism is introduced to heterogeneous node for energy saving and a multi-jump data transmission mode is applied for remote and wide-area applications. Furthermore, a new, geographical routing algorithm, named Hole-Forewarning Routing algorithm (HFR), is proposed to solve the problem of hole during routing path. Simulation results show that GBHHR has higher energy effocoency([1]) than traditional geographical routing and hierarchy routing.
