A proposal on void zone aware Greedy Forwarding method over MANET

Greedy Forwarding algorithm that is a typical location aided routing in MANET has a problem that it cannot find a route when a node faces a void zone (hole). Existing methods to solve the problem usually tries to escape the void zone just after it finds the zone and results in having a longer path. This paper proposes a revised effective greedy forwarding method by advanced sharing of the void zone information among nodes before route decision. It shows the effectiveness of the proposal by network simulation.
