Abstract
Current handoff techniques in integrated services wireless networks focus on the mobile-to-fixed node handoff and have not addressed issues regarding mobile-to-mobile handoff. Virtual connection extension based mobile-to-mobile handoff is a fast solution, but results in inefficient routes. Crossover switch based techniques provide better routes, but at the cost of call dropping during simultaneous handoff. We propose three crossover switch based techniques aimed at preventing call dropping due to disjointed connection and also improving the latency during handoff. Partial- rerouting/path-extension, which uses the features of mutual exclusion principle effectively, prevents call dropping and also invokes a route optimization phase. The route information based partial-rerouting/path-extension technique is aimed at preventing call dropping and also reducing handoff latency due to rerouting. Finally we propose a dynamic route information based technique that further reduces the handoff latency. A comparative evaluation of handoff latency and complexity of the proposed techniques with crossover switch based mobile-to-mobile handoff scheme is provided.
