Abstract
Ad-Hoc networks have an adaptive architecture, temporarily configured to provide communication between wireless
devices that provide network nodes. Forwarding packets from the source node to the remote destination node may
require intermediate cooperative nodes (relay nodes), which may act selfishly because they are power-constrained. The
nodes should exhibit cooperation even when faced with occasional selfish or non-cooperative behaviour from other
nodes. Several factors affect the behaviour of nodes; those factors are the number of packets required to redirect, power
consumption per node, and power constraints per node. Power constraints per node and grade of generosity. This article
is based on a dynamic collaboration strategy, specifically the Generous Tit-for-Tat (GTFT), and it aims to represent an
Ad-Hoc network operating with the Generous Tit-for-Tat (GTFT) cooperation strategy, measure statistics for the data,
and then analyze these statistics using the Taguchi method. The transfer speed and relay node performance both have an
impact on the factors that shape the network conditions and are subject to analysis using the Taguchi Method (TM). The
analyzed parameters are node throughput, the amount of relay requested packets produced by a node per number of
relays requested packets taken by a node, and the amount of accepted relay requested by a node per amount of relay
requested by a node. A Taguchi L9 orthogonal array was used to analyze node behaviour, and the results show that the
effect parameters were number of packets, power consumption, power constraint of the node, and grade of generosity.
The tested parameters influence node cooperation in the following sequence: number of packets required to redirect (N)
(effects on behaviour with a percent of 6.8491), power consumption per node (C) (effects on behaviour with a percent
of 0.7467), power constraints per node (P) (effects on behaviour with a percent of 0.6831), and grade of generosity (e)
(effects on behaviour with a percent of 0.4530). Taguchi experiments proved that the grade of generosity (GoG) is not the
influencing factor where the highest productivity level is, while the number of packets per second required to redirect
also has an impact on node behaviour.
