<p class="0keywords">Mobile Ad hoc networks do not have any form of centralized control as per their definition. Therefore, many challenges face the development of efficient protocols for such networks. One of the main challenges is the difficulty of extracting the total number of nodes in the network, this paper aims to find an estimate for this number using the average hop count for messages exchanged in the network. Experiments of this paper are conducted on Ad Hoc networks under DSR and AODV routing protocols. Results show a relation between network size and average hop count that can be used to predict the number of nodes in the network.<strong></strong></p>

Mobile ad hoc networks are an independent wireless network that is built without permanent infrastructure and base station support. Each node in the network uses a wireless connection for connections and acts not only as an end system but also as a path to accelerating packets. Meanwhile, the network nodes are mobile and can move in each path with changing steps, creating a great dynamic of the network. Therefore, the protocols set for general ad hoc networks are inappropriate for such a situation. In addition, the performance of ad hoc routing protocols decreases with increasing network size. In this context, suggest a new way to extend the recital of routing in MANETs: the on-demand Progressive Distance Vector (PAODV). It is a modified variant of the standard AODV routing protocol, which shrinks the dynamic path when an optimal path exists and switches the traffic to it. Simulation studies with NS2 show that the proposed method improves network performance as network size, weight, or flexibility increase.
