In recent years, wireless systems are picking up prominence to its crest today, as the client needs wireless network independent of their geographical position. Wireless system is a system set up by utilizing radio sign recurrence to convey among PCs and other system gadgets. There are number of characteristics in mobile ad hoc networks, such as the dynamic network topology, limited bandwidth and energy constraint in the network. Mobile ad hoc network is useful for different purposes e.g. military operation to provide communicate between squads, emergency case in out-of-the-way places, medical control etc. Each mobile node acts as a host in the network when it receives the information. Efficiency of the network is the main concern in mobile ad hoc network to increase the network performance. There are many routing protocols in mobile ad hoc networks to increase the network performance. Also routing and efficiency of the network are the challenging issues in MANETs. Clustering is an efficient way to improve the network performance and routing techniques. In this research, Cluster based routing protocol is been used and analyzed the performance of cluster based routing protocol on NS-2 simulator tool with random number of nodes graphically. Cluster based routing protocol is been used for clustering in which cluster head is elected on the basis of minimum if of node. CBRP uses only a single parameter to elect a cluster head that is not a good way to evaluate the performance of network graphically. In MANETs, nodes are mobile so it is difficult to analyze the performance of network and also all these techniques has less efficiency. It reduces the network performance and reduces quality of service. Different techniques have their own drawbacks. In this work, further enhancement is implemented in cluster based routing protocol to change its cluster head scheme. In this scheme, the node is selected as a cluster head which has a minimum weight among the neighbor nodes. This technique is totally dynamic in nature. Every time when simulation starts different cluster head will be chosen. The weight of node is changed after every simulation. The weight is calculated by using four parameters like trust, number of nodes, mobility and transmission power. The routing is possible only through on demand route of the network, due to this network traffic is less so delay will be reduced and PDR is high. The technique has been implemented in Network Simulator version 2 (NS2) with different number of nodes. The graphical results show that this protocol technique performs better than CBRP in terms of throughput, delay and packet delivery ratio in the network.
