Noise-Immune Network Layer of the Protocol Stack for a Wireless Sensor Network of a Tree Topology

Abstract

The paper presents the network layer of the protocol stack in wireless sensor networks. This stack makes it possible to implement wireless sensor networks of a tree topology, which are able to function in the presence of noise. We state the requirements for the network layer and propose a development to the keep-alive mechanism that forms the basis of the network recovery subsystem. We present a functional flow block diagram of the network layer proposed and its model based on the ns-3 simulator. We also describe the noise model. Our simulation allowed us to estimate how noise interferes with the network operation and to show that the network layer of the protocol stack for a wireless sensor network featuring a network recovery mechanism is efficient in the presence of noise
