Routing data through a wireless network is made challenging by impairments in the wireless medium, such as fading. Nevertheless, wireless routing if implemented, will result in tremendous cost-savings in next generation wireless networks. This paper examines centralized and decentralized approaches for wireless routing from a PHY/MAC perspective. We show that decentralized routing strategies are capable of realizing full spatial diversity gain if an appropriate level of channel knowledge is

Furthermore, we propose a new carrier sensing random access based routing technique designed to avoid collision and conserve network power. A numerical example is provided to demonstrate that the technique is capable of realizing full spatial diversity gain.
