| Abstract: | This paper reviewed some recent novel theories and algorithms of geographic routing for wireless sensor networks, and described the taxonomy. And discussed several typical next-hop node policies, presented the disadvantages of them. More speci-fically, captured the local minimum problem and gave the solutions to it in detail. In the end, pointed out the open research issues in this field. |
