Abstract: The wireless networks have a very bright future in networks and communications because of
which they have taken a high interest of the researchers. As the users increased the purpose to use MANETs,
they also became more diverse and wide due to which better performance is needed in MANETs. QoS is
needed for applications for an efficient communication and load balancing is a feature in the routing protocol
that can help in a better use of the resources and can help to increase the performance of the network. We
propose a new approach for load balancing in AOMDV routing protocol for MANETs that can enhance
the network performance by selecting paths using the temporal load on the intermediate nodes and by
distributing the load amongst the free nodes while transmission of data, which is proved by simulations in NS-2.

1 Introduction
MANET (Mobile Ad-hoc Network) is a collection of
mobile devices and is self configuring, dynamically
changing, multi-hop wireless network which forms a
communication network via multi hop wireless net-
work connection. It is a self-organizing network,
without any central control. Nodes in the network
communicate with another node only if it lies within
its transmission range. Mobile Ad-hoc networks have
potential applications in civilian and military envi-
ronments. The dynamic changes in the topology of
MANET make routing a challenging task, as the ex-
isting path is rendered inefficient and infeasible. The
major issues for mobile Ad-hoc networks are MAC
(Medium Access Control), routing, security and QoS
(Quality of Service) provisioning
[1]
, which is mainly
because of node mobility, link failure, limited avail-
able bandwidth. The routing challenge in MANETs
is to provide an optimal path in less amount of time
for data forwarding with limited power supply, pro-
cessing and memory resources
[2]
.
The problem in existing routing protocols is that
there is no fair distribution of the traffic amongst the
paths in the network the nodes that lie in more dense
areas are used more by different paths and hence are
exhausted and that leads to degradation in the per-
formance of the routing protocol. A load balancing
feature needs to be added in the existing protocols
to distribute the workload fairly in the network.
Using multipath routing protocols like AOMDV
can help in keeping backup routes in case of a route
breakage but still they are not providing any load
balancing feature because in case of less mobile con-
