Queuing Theoretic Analysis of a WSN based Earthquake Monitoring System

Abstract

Earthquake monitoring and detection has been in great
focus for many years. A possible solution of this problem is
the deployment of an efficient system that can generate the
warning for the earthquake as early as possible. This kind
of deployment not only helps to save human lives but also
provides support in exploring many hidden facts about great
disaster. In this paper, performance analysis of Wireless
Sensor Network (WSN) based earthquake monitoring system
is carried out using queuing theory. The WSN nodes
transmit their data to a centralized node which further
sends this data to main station using a wireless/wired
backhaul link. This scenario is modeled using two queues;
M/M/1 queue and M/D/1 queue. The performance of the
system is evaluated and compared in terms of mean system
delay and utilization for both queuing models. The results
reveal that the system delay decreases with increase in the
data rate of the communication link (server).
