Abstract—The capacity of a Mobile Ad-hoc Network
(MANET) can be severely limited due to interference
constraints. One way of improving the overall capacity of
ad-hoc networks is by the use of smart antenna system (SAS).
SAS has the advantage over traditional omnidirectional
antennas of being able to orientate radio signals into the
concerned directions in either transmission mode or in
reception mode. The omnidirectional antennas in broadcasting
over the whole network are the source of an excessive
redundancy of broadcast packet receptions within each node.
The SAS consist of a uniform linear array (ULA) and the signal
processing unit, employing constant modulus algorithm (CMA)
is implemented using MATLAB R2012a. For the MANET we
used geographic routing protocol (GRP) which is Optimum
Network Engineering Tool’s (OPNET’s) custom model routing
protocol where each node uses the global positioning system
(GPS) to identify its own position and implemented in OPNET
modeler 14.5. A co-simulation is then made between OPNET
modeler 14.5 and MATLAB R2012a to take advantage of SAS
and uses it with MANET in OPNET 14.5. Using this approach,
exploring SAS for MANET improves throughput and Signal to
Noise Ratio overall the network and decreases Bit Error Rate
compared to omnidirectional antenna.
Index Terms—CMA, mobile Ad Hoc network,
omnidirectional antenna, smart antenna system.
