Routing holes problem is always hot in the research of Wireless Multimedia Sensor Networks.An efficient bypassing hole scheme BHRGR,which is aimed at the characteristic of geographic routing is presented.This scheme ascertains the position of holes by sending an observer packet in advance to get the information of nodes on the boundary of holes.It constructs a virtual rectangle which covers the hole to engender dynamic intermediate destination nodes.An efficient bypassing hole route is formed.Simulation res...
