A routing algorithm is position-based if a node forwards its packet according to the position information (i.e., coordinates in the plane). GREEDY, COMPASS, ELLIPSOID, and FACE are four famous position-based routing algorithms. The former three algorithms run very fast but cannot guarantee message delivery. On the other hand, FACE does not run fast but it guarantees message delivery. It is indeed a challenge to develop an algorithm that can run very fast and can have high delivery rate at the same time. The purpose of this thesis is to propose two such algorithms. Experimental results show that our algorithms are quite good.
