针对无线传感器网络中的空洞扩散问题，提出了一种新的地理空洞绕过转发协议（HBF）。为了支持有效的漏洞旁路，HBF协议使用虚拟圆来模拟漏洞，该虚拟圆的半径在一定范围内可调，并且基于每个分组来计算。如果需要的话，与虚拟圆相关联的信息将用于选择锚点以绕过洞，以便分组到达特定的汇聚节点。HBF协议的设计目标是平衡实际孔边界附近的节点之间的业务负载。使用HBF协议，数据包总是被发送到最近的接收器，并且在数据包到达网络中的接收器（或其中一些）的传递中考虑用于绕过空穴的额外距离。仿真结果表明，HBF协议在分组投递率和网络生存时间方面优于现有的空洞绕过协议。
The authors propose a new geographic hole-bypassing forwarding (HBF) protocol to address the hole diffusion problem in wireless sensor networks (WSNs). To support efficient hole-bypassing, the HBF protocol models a hole using a virtual circle whose radius is adjustable within a certain range and is calculated on a per-packet basis. The information associated with the virtual circle will be used, if needed, for selecting an anchor point to bypass the hole in order for a packet to reach a particular sink node. The design objective of the HBF protocol is to balance the traffic load among the nodes near an actual hole boundary. Using the HBF protocol, a packet is always sent to the closest sink and the extra distance for hole-bypassing is considered in the delivery of data packets to reach the sinks (or some of them) in the network. The simulation results show that HBF outperforms existing hole-bypassing protocols in terms of packet delivery ratio and network lifetime.
