Abstract
Novel preventive link maintenance scheme based on directional antennas has been proposed to extend the life of the link for Mobile Ad Hoc Networks (MANET). We use the ability of directional antennas to orientate radio signals into the desired directions. To be more specific, preventive orientation warning is generated and sent to previous node in the path to initiate directional pattern. Link is considered in danger when received packet power is close to minimum detectable power. We call orientation handoff to the process of changing the pattern of antenna from omnidirectional to the directional. We do a comparative performance study between omnidirectional and directional antennas for DSR (on-demand routing protocol) using simulation with OPNET. By using directional antennas, substantial gain is achieved in terms of end-to-end delay, aggregate throughput, and routing overhead. The proposed scheme is general and can be used with any other on demand routing algorithms.
