Filardi N., Caruso A., Chessa S. Virtual naming and geographic routing on wireless sensor networks. In: IEEE Symposium on Computers and Communications. ISCC'07 (Aveiro, Portogallo, 1-4 July 2007). Proceedings, pp. 609 - 614. IEEE, 2007.
We consider the problem of routing with guaranteed de- livery in wireless sensor networks where physical locations of the sensors are not known. We propose a naming proto- col which defines a 2-dimensional coordinate system and a routing protocol (Ibrid) which ensures guaranteed delivery of packets. We show by means of simulation that in realis- tic settings where the network includes voids and obstacles, Ibrid finds routess hortest than those obtained with existing geographic routing algorithms over physical coordinates.
