Simulating the Wireless Sensor Networks Coverage Area in a Mesh Topology

Abstract

Wireless Sensor Networks (WSNs) have many crucial applications. WSNs can be created from number of deployed sensor nodes in a certain area. These nodes can be deployed randomly. Sensors are mainly utilized to track or monitor any modifications in a surrounding area. They can be used to monitor, gather information then, process and transfer the sensed data to a certain sink node. One of the main objectives of any proposed WSNs is to safely transfer the sensed data with minimum energy consumption and with reduced packet losses. The data transmissions in WSNs are affected by the network topology. The network topology in this paper is mesh topology. Each sensor in such a topology can communicate directly with its neighbors if they are located in its transmission range. The data transmission is performed through the shortest path. The problem in this work is to analyze and evaluate the effects of mesh topology on the coverage area and evaluate the cases when many sensor nodes send messages at the same time. The simulation results showed an average of 33.8 messages are sent and received in scenario 1. Four selected nodes are tested and their sent messages are (359, 531, 197 and 145) respectively.
