Network protocol and Infrastructure

For a Wireless Sensor Network

Invitation to Tender

Introduction

Wireless Sensor Networks(WSN) comprise of tiny devices with a capability of sensing, communication and computation are spread over a physical environment, perhaps for a limited period, with a common objective to collaborate to provide a distributed and robust sensing, storage, and communication service. These devices can be dispersed over a hostile battlefield or harsh environment to achieve a task. Wireless sensor networks have an enormous potential impact in the future in many fields such as military, civil, health and habitat monitoring.

Project Overview

California Department of Forestry and Fire Protection would like to deploy a wireless sensor network on Ahjumawi Lava Springs State Park. The network will feed live data to the nearby control processing centre via a long distance wireless link.

Wireless Sensor Network

The project is looking to deploy approximately 1500 custom built battery operated wireless sensors. The sensors must operate on a globally compatible ISM band with direct sequence spread spectrum. The sensors should have expansion connector for light, temperature, RH, Barometric, Pressure, Seismic, acoustic sensors. Battery powered WSN usually have a limited lifetime. The primary goal of this project is to come up with novel communication strategies that will maximize the lifetime of these battery operated sensors.

The project intends to share this live data with the scientific community across the globe. This will require a web server built into the design.

The scope of this project is limited to a new secure communication protocol design for WSN. For WSN you will need to specify protocols for physical, routing and MAC layer of the protocol stack. Security must be considered across the full protocol stack.

TECHNICAL REQUIREMENTS

Energy efficient Protocols specification required for
- Network Layer
- Mac Layer
- Physical Layer
- Security

The protocols must ensure efficient and uniform consumption of energy across the network.
Frequency choice for sensor node communication within the network.
Long distance communication link must be specified.
Logical addressing scheme (Equivalent of IPv4 or 6).
Enhanced Security solution across the three layers.

COST INFORMATION REQUIRED

For this exercise, no cost information is required though information on power saving can be included.

Tasks Requirements

AMY Networks is a consultancy business that designs, installs and operates different types of wireless and wired networks for businesses and research organisations. As one of their project leaders you have been asked to respond to an ITT (Invitation to Tender) for this network design. The network solution will include the wireless sensor network logical design along with protocols specifications.

The ITT document is included with this ICA. The tender that you produce in response to the ITT should take the following form.

Part 1 – Design

Part 2 – Design Report (4000 words)

60%

The report must provide

Description for the protocols you have chosen for the wireless sensor network and how they will prolong the network life time (Restrict discussion to Routing, MAC and Physical Layer) (20%).
Enhanced security solution for the network including identification and mitigation of the security risks (30%).
Conclusion/Reflection:
- Realistic and insightful conclusions drawn from the research.
- A full discussion about the nature of future developments should be included (10%).

The discussion should include a plan for integrating the different network protocols into the new network design. Your discussion must be supported by published research or simulation.

Part 3 – Presentation

10%

Marks will be awarded for the overall presentation of your work. Your work should be of a professional standard.
