Mobile Ad-hoc networks are self organizing and self-configuring multichip wireless networks where, the structure of the network changes dynamically. A routing protocol in MANET should fairly distribute the routing tasks among mobile hosts. Most current routing protocols for mobile Adhoc networks consider the shortest path with minimum hop count as optimal route without any consideration of any particular node’s traffic and thus degrading the performance by causing serious problems in mobile node like congestion, power depletion and queuing delay. Therefore it is very attractive to investigate Routing protocols which use a Routing Metric to Balance Load in Adhoc networks. We present various load Balanced Routing protocols for efficient data transmission in MANETs. Keywords— Load Balancing, Mobile Adhoc Networks (MANETs), Routing I. INTRODUCTION In Ad hoc networks, it is essential to use efficient routing protocols that provide high quality communication. To maintain portability, size and weight of the device this network has lot of resource constrain. The nodes in MANET have limited bandwidth, buffer space, battery power etc. So it is required to distribute the traffic among the mobile host. A routing protocol in MANET should fairly distribute the routing tasks among the mobile host. An unbalanced traffic/load distribution leads to performance degradation of the network. Due to this unbalancing nature, few nodes in the network are highly loaded with routing duties which causes the large queue size, high packet delay, high packet loss ratio and high power consumption. This problem leads to solution of load balancing routing algorithm for MANET. MANET consists of mobile hosts equipped with wireless communication devices. The main characteristics of MANET is, it operate without a central coordinator ,Rapidly deployable, self configuring, Multi-hop radio communication, Frequent link breakage due to mobile nodes ,Constraint resources (bandwidth, computing power, battery lifetime, etc.) and all nodes are mobile so topology can be very dynamic. So that the main challenges of routing protocol in MANET is , it should be Fully distributed, Adaptive to frequent topology change ,Easy computation & maintenance, Optimal and loop free route, Optimal use of resources, It provide QoS and Collision should be minimum. Classification of routing protocols in MANET:- The routing protocols in MANET are classified depending on routing strategy and network structure. According to the routing strategy the routing protocols can be categorized as Table-driven and source initiated, while
