Mobile Ad Hoc network is a group of nodes or a collection of nodes; they communicate with each other without any central administrator. Life of node as well as network is directly proportional with battery capacity. Lifetime of the node usually depends upon the load over the node. If a node is overly loaded, that means it is forwarding more packets and hence it might die out soon. So load balancing is another aspect to be considered while designing the routing scheme for mobile ad hoc networks. This paper presents the survey of various studies regarding the load balancing in the mobile ad hoc networks.
