Within the vision of ubiquitous multimedia, using multimedia sensor nodes, such as audio, image, and video sensor nodes, in wireless sensor networks can dramatically enhance the capability of sensor networks for event description. Different kinds of holes can easily appear in sensor networks. For example, tens of sensor nodes can consist of a hole in a small area because of overload. Efficiently and reliably transmit these multimedia streaming data back to the base station while bypassing these static or dynamic holes is one of the key challenge issues. In this paper, we propose a new Two Phase geographical Greedy Forwarding (TPGF) routing algorithm for exploring one or multiple optimized hole-bypassing transmission paths. We demonstrate the execution of TPGF routing algorithm by using our implemented simulator NetTopo. Comparison and simulation results show that our algorithm can effectively solve the identified problems and is better than the famous GPSR routing algorithm in both functionality and performance aspects.
