Optimizing end to end routing performance in wireless sensor networks

摘要: The geographic routing is an ideal approach to realize pointto-point in wireless sensor networks because packets can be delivered by only maintaining a small set of neighbors' physical positions. assumes that packet moved closer the destination network topology if it geographically space. This assumption, however, holds model where uniformly distributed nodes communicate with neighbors through channels perfect reception. Because this oversimplifies spatial complexity network, may often lead local minimum or low quality route. Unlike forwarding, ETX-embedding proposed paper accurately encode both network's topological structure and channel size nodes' virtual coordinates, which makes possible for greedy forwarding guide along optimal path. Our performance evaluation based on MICA2 platform TOSSIM simulator shows outperforms previous approaches.
