Recently proposed beaconless georouting algorithms are fully reactive, with nodes forwarding packets without prior knowledge of their neighbors. However, existing approaches for recovery from local minima can either not guarantee delivery or they require the exchange of complete neighborhood information. We describe two general methods that enable completely reactive face routing with guaranteed delivery...
Depth First Search (DFS) and position based routing algorithms were proposed in literature. These are localized algorithms that guarantee the delivery for connected ad hoc and sensor wireless networks modeled by arbitrary graphs, including inaccurate location information for a destination node. This paper first optimizes an existing DFS based routing scheme by eliminating from the candidate list neighbors...
