Poster Abstract: Geographic Forwarding and Adaptive Load Balancing in Wireless Sensor Networks

In this poster, we wish to present some novel results achieved in the field of cross-layer geographic routing protocol design. Our protocol encompasses different operating features that are aimed at an overall best effort optimization of delivery performance and routing efficiency. Namely, it uses a joint MAC and routing message handshake to select one of the available relays and routes toward a common final sink. It includes a means for routing around connectivity holes and a back-to-back data transmission to improve channel use once access rights are achieved. Our results indicat that this protocol is simple in concept and thus fairly easy to implement on real motes, while offering a good performance in terms of delivery effectiveness.
