Abstract
In this paper, we investigate the impacts of applying game
theory on the network throughput, network voltage loss
and accuracy of malicious node detection to wireless sen-
sor networks. We implement a protocol which the sensors
use when deciding whether or not to forward packets they
receive from other sensors in order to conserve power.
Nodes in a wireless sensor network accomplish this by
optimizing their decision making based on a framework
using game theory. De¯ning a suitable cost and pro¯t to
routing and forwarding incoming packets and keeping a
history of experiences with non-cooperating nodes drives
malicious nodes out of the wireless sensor network.
