Performance of the beacon-less routing protocol in realistic scenarios

The beacon-less routing protocol (BLR) is a position-based routing protocol for mobile ad-hoc networks that makes use of location information to reduce routing overhead. Unlike other position-based routing protocols, BLR does not require nodes to periodically broadcast hello messages. This avoids drawbacks such as extensive use of scarce battery-power, interferences with regular data transmission, and outdated position information in case of high mobility. This paper discusses the behavior and performance of BLR in realistic scenarios, in particular with irregular transmission ranges. BLR has been implemented using appropriate simulation models and in an out-door test-bed consisting of GNU/Linux laptops with wireless LAN network interfaces and GPS receivers.
