Sažetak
This paper investigates the potential of smart routing in minimization of radio environment pollution in cognitive ad-hoc wireless networks. A wireless ad-hoc sensor network based on the IEEE 802.11b standard is used as a simulation testbed to determine statistical distribution of interference levels. Three different routing methods are used – flood routing, location aware routing (LAR) and a simultaneous localization and radio environment mapping based routing (SLAM routing). Results show that LAR partially reduces interference by limiting number of transmissions for a single packet resulting in lower interference. SLAM based routing causes significantly lower interference throughut the network by both lowering the number of transmissions and reducing the radiated power close to the minimum required for a successful transmission, resulting in an interference noise floor 19.7 dB below the flood routing protocol.
