Book excerpt: Instruments that observe entire systems in situ, using a relatively large number of interconnected and inexpensive nodes are expected to be enabled primarily by Wireless Sensor Networks (WSNs). These instruments place certain service demands on the underlying network e.g. connectivity, coverage, quality of service assurance arid energy efficient utilization. The IEEE 802.15.4 Low Rate Wireless Personal Area Network (LR-WPAN) specification is kitted with components that can deliver (or at least provide support for the delivery of) these services. As this specification is relatively new, with the first version released in 2003. a revision in 2006 and an update in 2007, it was incumbent that its operational mechanisms were well understood, to allow for efficient cross layer interaction between the different processes that make up the specification and existing or new higher layer protocols. To that end. in this thesis, we created a model of the specification that captured all but one of its functional requirements i.e. the security component. We studied and evaluated this model using a combination of a high fidelity simulation and mathematical tools. From these studies, we were able to identify areas in which the specification could be improved upon without extensive modification. Also identified were areas of cross layer interactions. The knowledge gained from the above was used to propose and evaluate three higher layer mechanisms/protocols including; a scalable dynamic topology control algorithm, a routing and transport protocol. All of which leveraged the services offered by the IEEE 802.15.4 specification to deliver on the objectives required of a WSN. These proposed higher layer mechanisms/protocols were thoroughly evaluated in order to demonstrate their flexibility, scalability and energy efficiency capabilities.
