Alternatives to Face Routing for Localized Nodes in Wireless Sensor Networks
نویسندگان
چکیده
Geographic routing protocols for wireless sensor networks are considered. While a combination of greedy and face routing is a solution with a good performance well documented in the open literature, it requires the procedure of network graph planarization which is difficult to implement in real wireless networks. In this document, the possibilities of substituting face routing are analysed. It is assumed that wireless nodes have not any knowledge about the network topology. The algorithms that enable to recover greedy routing from local maxima failures are discussed and their performance is validated through computer simulations.
