are stationary. The prediction of the movement of these nodes is difficult. The attacks and unreliability are the arising issues which are caused due to the dynamic nature of MANETs [2]. The most important part of MANETs is routing which makes a node not only complete the tasks related to it but also help in accomplishing tasks which are related to other nodes. As the MANETs are prone to attacks there is a major requirement for establishing a secure as well as trustworthy end-to-end path for them. The routing protocols used in the network are classified into tree broader categories. The Proactive also known as the table-driven routing protocols are one of the categories. Here, the maintenance of routing tables which are used to store routing information is needed [3]. Updates are to be propagated according to the changes made in the network topology. This helps in maintaining a consistent network view. Another category is the reactive routing which is also known as the on-demand routing protocol which does not need to maintain the routing information or activity when there is no communication in the network. In an on-demand manner, the routes are searched within the network when there is need to provide communication from one node to another. A connection is established which helps in transmitting as well as receiving the packets amongst each other. The route request packets are flooded in the network in order to discover a route. The combination of reactive and proactive routing protocols, are known as the hybrid protocols. The routing protocol which divides the network into various zones is known as the Zone Routing Protocol (ZRP). This protocol provides a hierarchical architecture through which every node needs to maintain additional topological information which also needs extra memory [4].
network which is self configuring and de-centralized in nature. The mobile nodes can join or leave the network when they want due to which routing issues may raised in the network. The routing protocols are used to establish efficient and secure path from source to destination. It is been analyzed that AODV protocol is efficient protocol among all other protocols for the path establishment. In this work, the performance of AODV protocol is improved using bio-inspired techniques for the path establishment in the network. The performance of proposed algorithm is test in network simulator version 2 and it gave good performance as compared to other protocols in terms of various parameters.

1. INTRODUCTION The network in which the nodes communicate with each other using the radio waves is known as Mobile Ad hoc network (MANET). The range of radio waves is a very important factor as the nodes which come under this range are able to communicate amongst each other. Intermediate nodes are required for the purpose of routing packets in the case of nodes which are out of range. For the purpose of communication, a wireless interface is required with respect to each node [1]. There is no fixed infrastructure as access points or base stations needed in these types of networks. MANETs are distributed and do not require any fixed infrastructure. For the purpose of transmission of relay messages, independent communication is held in case of nodes within the transmission range and the nodes outside this range are dependent on other nodes. This results in creating a multi-hop scenario which helps in transmitting the packets from source to destination with the help of certain intermediate hosts. Amongst the various challenges observed in MANETs, the symmetric and asymmetric links are a major concern. There are various mobility patterns followed by nodes. There are nodes which are highly mobile whereas other nodes which

AODV routing protocol: The Ad Hoc On-Demand Routing Protocol (AODV) is a reactive routing protocol which is used in the ad hoc mobile networks. Using this type of protocol, the routes are created within a network only when there is a need to provide communication. Traditional routing tables are used for providing one entry per destination and sequence
