Experiments with wireless sensor networks have shown that unidirectional communication links are quite common. What is even more, they have also shown that the range of a unidirectional link can exceed that of a bidirectional one by far. Still, most of todays routing protocols do not use them, they only eliminate their implications. Those protocols that do use unidirectional links introduce a lot of protocol overhead. In this paper we present Buckshot Routing, a robust, yet simple source routing protocol for dense wireless networks with lossy or unidirectional links, which reduces the overhead generated by route discovery and route maintenance significantly. Key words: wireless sensor networks, source routing, robustness, dense networks
