Optimizing Data Collection in Wireless Sensor Networks

Problem Definition

Problem Description: The increasing use of wireless sensor networks in various applications such as environmental monitoring, smart cities, and industrial automation has highlighted the importance of efficient data collection. However, the existing studies on data collection in wireless sensor networks have primarily focused on large-scale random networks with uniform sensor deployment. In reality, sensor nodes are often deployed in an arbitrary manner and the number of sensors may not be as large as assumed in previous studies. This discrepancy in sensor deployment raises the need to study the capacity of data collection in arbitrary wireless sensor networks. The efficiency of data collection directly impacts the performance of the sensor network, and it is crucial to determine the upper and lower bounds for data collection in arbitrary networks under protocol interference and disk graph models.

In this context, the development of a method that can achieve order-optimal performance for data collection in arbitrary sensor networks is essential. Additionally, understanding the capacity bounds for data collection in scenarios where communication between nodes is hindered by path fading or obstacles is crucial for designing effective data collection protocols. Therefore, there is a need to address the problem of efficiently collecting data in arbitrary wireless sensor networks by deriving capacity bounds, developing order-optimal methods for data collection, and designing protocols that consider communication challenges such as path fading and obstacles.

Proposed Work

The research work proposed in this study titled "Capacity of Data Collection in Arbitrary Wireless Sensor Networks" focuses on the efficient collection of data in wireless sensor networks to ensure optimal network performance. The project explores data collection in TDMA-based sensor networks in order to maximize capacity. While previous studies have primarily focused on large-scale random networks, this research recognizes the need to study data collection in arbitrary networks where sensor nodes may not be uniformly deployed and the number of sensors may be smaller than assumed. By deriving upper and lower bounds for data collection in arbitrary networks under protocol interference and disk graph models, the study aims to develop a BFS tree-based method that achieves order-optimal performance for any arbitrary sensor network. Additionally, the research utilizes graph models to study capacity bounds for data collection in scenarios where nodes cannot communicate due to path fading or obstacles.

Lastly, a design is proposed for data collection under a Gaussian channel model. This project falls under the categories of NS2 Based Thesis Projects and Wireless Research Based Projects, with specific focus on Mobile Computing Thesis and WSN (Wireless Sensor Network) Based Projects. The software used for this research includes NS2.
