Introduction

One of the key challenges to realize the promise of large-scale wireless sensor networks (WSNs) consisting of hundreds or thousands of tiny sensor nodes is the design and development of the middleware for sensor network management. The middleware is the software that interfaces between the low-level sensor devices and the high-level applications. With the appropriate middleware support, the WSN can accomplish the design goals in an energy-efficient, robust, accurate, and scalable manner. The number of sensor nodes in the system can be increased without the need to modify the middleware, until its scalability limit is exceeded.

We are designing the middleware of large-scale WSNs in a modularized manner such that most of its components can be re-used to cater for growth in the future. The middleware services are based on a layered architecture. Each layer of the middleware consists of software components that provide services to the application or other layers via Application Programming Interfaces (APIs). Currently we are designing the middleware components on top of TinyOS, which is a popular embedded operation system for WSNs.
