摘要：Even though geographic routing has many advantages and has shown a great potential, the inaccurate knowledge of local geographic topology can greatly affect routing performance. This not only leads to a larger packet delivery latency, more collisions and energy consumption but can also result in a routing failure. They perform effective forwarding decisions, based on the positions of their immediate neighbors. To maintain neighbor position, periodic broadcasting of beacon packets that contain the geographic location of the nodes is a popular method used. In our work called on-demand georouting reduces control overhead compared to the proactive schemes which provides reliable routing at the same time with less energy consumption. It consists of three mechanism, they adopt different schemes to obtain topology information. Firstly, SOGR-GR purely relies on one hop topology information. Secondly, SOGR-HR a hybrid scheme which combines geographic and topology-based mechanisms. Thirdly, SOGR-EE split a whole network into regions and combines greedy and SOGR-HR routing to provide energy efficient and reliable routing
