Abstract

Routing in mobile ad hoc network (MANET) has been a subject of extensive research over the past several years. Location-based geocasting and forwarding routing protocol (LGF) is based on location information to reduce flooding and routing overhead. Unlike other position-based routing protocols, neighboring nodes in LGF that are in the forwarding zone will rebroadcast route request packet and send a route reply to the source. Other nodes that are beyond this zone will not participate. This algorithm will reduce routing overhead, wireless bandwidth used and flooding of packets in the route discovery phase. This paper outlines the implementation of LGF in a real MANET test bed that integrate GPS-free indoor location tracking mechanism with geocast-enhanced AODV-bis, an enhanced AODV-bis routing protocol which have been developed recently.
