ABSTRACT Mobile ad hoc Networks (MANETs) show an astonishing qualities in the concept of networks which are used without wires. MANETs experience numerous communication medium restrictions such as constrained storage of memory and development of effectual routing protocols. Furthermore, multihop routing mechanism employed in MANETs gives rise to the contention in the channel and jamming within the network. This limits the effectiveness of the network which reduces the energy efficiency of the network and also lessens the routing performance of MANETs. Hence, the major matter in MANETs is to minimize the congestion and contention in order to enhance the routing mechanism. Hence, in this paper, a novel protocol is put into practice having an enhanced route discovery mechanism which is implemented in order to avoid the congestion during the routing. The proposed protocol chooses the route for the transference of information on the basis of load within the traffic on the node and then resets the route with the change in topology. The protocol is then integrated with the proposed algorithm Pollination Based Optimization (PBO) algorithm. This is an efficient technique for transmission that requires a link for longer period of time. The simulator used for the simulation of the work is Network Simulator-2 (NS-2). Simulation results have been carried out showing that the route optimization and enhancement in the route discovery using Pollination Based Optimization (PBO) algorithm.

INTRODUCTION Mobile Ad-Hoc Networks (MANETs) is a wireless network integrated with the abilities to organize themselves incessantly. These networks are infrastructure reliant networks which are made up of numerous nodes having mobile properties. These nodes are linked to each other in a wireless behavior. MANET is an independent network where the nodes are positioned in a haphazard manner [1]. The momentum of nodes in the MANETs is not similar to each other. Therefore, the connectivity of nodes with other devices changes more often [2]. The primary issue in the construction of MANET is that each device has to be equipped properly for the continuously routing of data. These types of nodes are associated with each other straightforwardly[3][4]. The perception of MANET is dissimilar from other sensor networks because of the use of multihop routing technique. In MANETs, the nodes always employ an intermediate node for the transference of information from one node to another[5]. There are various advantages of MANET which are clarifies as follows. A. Self-Configuring and self-governing Networks MANET is made up of several nodes having the capabilities to assemble themselves. These types of networks do not depend on the infrastructure of nodes which are mobile in nature. Because of this concept, the central administration is not necessary in MANETs [3]. B. Routing system The multihop routing technique plays a proficient responsibility. Each node deployed in MANET has to play the role of host as well as router to process the information. The node which exhibits the properties of as a host and router is named as intermediate node [4]. C. Type of Topology MANETs show the Dynamic topology system because of the independent activities of numerous nodes which get positioned in a random manner. The nodes can connect to the network or depart from the network at any instant of time [6][7]. RESEARCH ARTICLE OPEN ACCESS
