An Interfererence Minimization and Predictive Location Based Relaying for Ad-Hoc Cellular Systems

We propose a predictive location based relaying for hybrid cellular and ad-hoc systems that can provide interference minimization to uplink transmission. Location Information Server (LIS) managed the mobile´s routing information with centralized scheme. To maintain the routing correctness, mobile must send location information within a relatively short time period. However the tradeoff as the location-update period decreases is the increase in the overall cellular overhead. To overcome this problem, a predictive location-based routing scheme is proposed. Simulation results show that interference is greatly improved with very low cellular overheads.
