Abstract	:	A mobile ad hoc network or MANET is an autonomous collection of mobile users (nodes) that communicate over wireless links. This mobility means that the network topology may change rapidly and unpredictably over time. Mobility also effects density, as nodes in an ad hoc network are potentially in motion, so density in an ad hoc system varies due to mobility. Increasing density can result in congestion, collisions, and increased power consumption. When density is low, the coverage tends to be poor. Due to these reasons, density is considered as an important metric for defining a network environment. The density of an ad hoc network is referred to when performance metrics are defined, when researchers define the context of an ad hoc network for experiments, when different protocols are developed and when different kinds of protocols are compared. The metric of density is considered directly or indirectly in various research works. Despite the importance of density, little research appears to have been done to determine its value in an ad hoc network environment. Density of ad hoc networks can be determined by applying two basic anthropogenic counting concepts; population census and traffic analysis. The design of two density determining algorithms for ad hoc networks is proposed: a census of nodes and an algorithm based on traffic analysis. Since ad hoc networks are dynamic in nature, density can change over time because of increases or decreases in the number of nodes in the network. Therefore, density determined at one instance may not be applicable for another instance. The proposed algorithms also react to these changes in density due to mobility.
