A geographic routing protocol utilizing link lifetime and power control for mobile ad hoc networks

Abstract

It is known that existing geographic routing cannot maintain its capability in sparse networks compared to that in dense networks. Furthermore, mobile environments worsen the performance of greedy forwarding based routing. To become a practical protocol candidate, it is necessary to sustain stable performance irrespective of a network topology and mobility. For this purpose, we propose a novel geographic routing protocol, Power Boosting Geographic Routing with link lifetime estimation (PBGR), which utilizes link lifetime estimation and power control on the top of geographic routing. Specifically, the link life time estimation can upgrade the performance of greedy forwarding under mobile scenarios and the power boosting enables greedy forwarding to maintain its strength in sparse networks. Simulation results exhibit superior performance of our protocol.
