IMPLEMENTATION OF GEOCAST-ENHANCED AODVbis ROUTING
PROTOCOL IN MANET

ABSTRACT

Mobile Ad Hoc Network (MANET) represents a complex
distributed system that enables seamless internetwork in
areas with no pre-existing communications
infrastructure. Far less effort has been done on the
real-world basis, with intensive evaluations through
simulations. This paper outlines our experiences with
the implementation of MANET testbed based on
geocast-enhanced AODV-bis module. AODV-bis is an
improved design of MANET routing protocol, from the
lessons learned beyond the Experimental RFC AODV
effort. The main goal of our research is to develop and
verify the practicality of AODV-bis (Ad-hoc On-Demand
Distance Vector-bis) routing protocol, featuring path
accumulation. To enhance AODV-bis, location
information is utilized during route discovery to limit
forwarding zone by geocasting. It can be done with
only little modification of packet format. We found that
AODV-bis, compared to AODV, is a more powerful
routing protocol especially in disseminating route
information. Its overall performance is further
improved with the aid of geocasting.

1. INTRODUCTION

The novel MANET is a collection of mobile computing
devices that communicate via wireless links, without the
aid of infrastructures. Its topology changes
unpredictably and nodes are free to join or leave
arbitrarily. Unlike Wireless LAN, MANET, as
illustrated in Figure 1, does not rely on centralized
administration and the control of the network is
distributed among the nodes. Each node may function
as a router to assist others searching for route. The
applications of self-organized MANET are vast. It can
be used in emergency services, conferencing and
instantaneous classroom, home or community
networking and battlefield communications.

AODV-bis ROUTING PROTOCOL

AODV [3] has been promoted to Experimental RFC of
IETF MANET charter [4] since July 2003. AODVjr
[5] effort investigated an approach to simplify the overall
AODV design. It is done in simulation, and has proved
that for networks of limited size, reliable
communications can be managed by implementing only
a very limited number of AODV features. Thus,
AODV-bis was proposed as MANET WG Internet draft
[6] in October 2003. Many features are no longer
mandated in AODV-bis compared to AODV, several
redundant protocol semantics. These modifications are
important especially for resource-limited mobile
computing devices such as wearable computers.
