Simulative analysis of saturation condition in a pedestrian ad-hoc network

In this paper, we consider a particular type of wireless ad-hoc networks, namely Pedestrian Ad-hoc NETworks (PANETs), where all nodes in the network are sources and destinations of information. In particular, we refer to an application where nodes report their presence by broadcasting an hello message to all other nodes in both IEEE 802.11 monodimensional and bidimensional scenarios. The system performance, in terms of throughput and delay, is analyzed using a recently proposed broadcasting protocol, namely Irresponsible Forwarding (IF) and its extension, denoted as Silencing IF (SIF). The proposed framework allows to determine a critical hello generation rate below which multi-source broadcasting is efficient.
