Implementing a Small Scale MANET Testbed based on Geocast-Enhanced AODV-bis Routing Protocol

Abstract

Mobile Ad Hoc Network (MANET) has attracted extensive research interests over the past several years. However, far less effort has been done on the real-world basis, with intensive evaluations through simulations. This paper outlines our experiences of developing and implementing the MANET testbed based on geocast-enhanced Ad-hoc On-Demand Distance Vector-bis (AODV-bis) routing protocol. AODV-bis is an improved design of MANET routing protocol featuring path accumulation, from the lessons learned beyond the Experimental RFC AODV effort. To enhance AODV-bis, location information is utilized in route discovery phase to confine the request zone based on geocasting instead of broadcasting. Compared to AODV, we found that AODV-bis is a more powerful routing tool especially in route dissemination. Finally, its overall performance is further improved by the aid of location information.
