Abstract:
1. A method for communicating data in an integrated sensor network having one or more nodes coupled to an optical sensor network and a radio frequency wireless sensor network, each node having an optical link and a wireless link, the method comprising: a. determining a transmission path having one or more hybrid hops for packet transmission over the optical sensor network and the radio frequency wireless sensor network, each hybrid hop including optical and wireless links between two neighboring nodes; and b. selecting a set of optical and wireless links for the optical sensor network and the radio frequency wireless sensor network to minimize contiguous wireless links; c. coordinating transmissions over the optical sensor network and the radio frequency wireless sensor network with a quality-aware cross-link optimization; d. transmitting a packet over both wireless and optical links to improve performance through link diversity; and e. automatically switching to a good link if a bad link is detected.
