Integration and Analysis of Neighbor Discovery and Link Quality Estimation in Wireless Sensor Networks

الملخص EN

Network connectivity and link quality information are the fundamental requirements of wireless sensor network protocols to perform their desired functionality.

Most of the existing discovery protocols have only focused on the neighbor discovery problem, while a few number of them provide an integrated neighbor search and link estimation.

As these protocols require a careful parameter adjustment before network deployment, they cannot provide scalable and accurate network initialization in large-scale dense wireless sensor networks with random topology.

Furthermore, performance of these protocols has not entirely been evaluated yet.

In this paper, we perform a comprehensive simulation study on the efficiency of employing adaptive protocols compared to the existing nonadaptive protocols for initializing sensor networks with random topology.

In this regard, we propose adaptive network initialization protocols which integrate the initial neighbor discovery with link quality estimation process to initialize large-scale dense wireless sensor networks without requiring any parameter adjustment before network deployment.

To the best of our knowledge, this work is the first attempt to provide a detailed simulation study on the performance of integrated neighbor discovery and link quality estimation protocols for initializing sensor networks.

This study can help system designers to determine the most appropriate approach for different applications.
