| Summary: | Transmitting video over Mobile Ad-hoc networks
(MANETs) is a challenging task because it is severely affected by
the various properties of the MANETs such as mobility, dynamic
change in topology, lack of fixed infrastructure, resource
constraints and limited bandwidth. Most of the existing MANETs
routing protocols are not cope with QoS metrics (E2E-delay, jitter,
Packet Delivery Ratio (PDR%)) required to efficiently transmitted
video contents. This paper investigates the efficient MANETs
routing protocols that can provide a high QoS for video
conferencing over MANETs through simulation experiments that
vary in network sizes and density of mobile nodes. The simulation
carried out through OPNET 14.5 modular. The routing protocols
under the investigation are Ad hoc on Demand Distance Vector
(AODV) as the reactive routing protocol, Optimized Link State
Routing (OLSR) as proactive, and Geographic Routing Protocol
(GRP) as position-based. The goal of our simulation is to evaluate
the impact of the mobility and scalability on the performance of the
above routing protocols for video conferencing over MANET in
order to identify which MANET routing protocols grantee the
desirable QoS metrics. From our simulation study we found that
OLSR outperforms AODV and GRP when MANETs scalable and
becomes dense |
