A Modular Framework for Real-time Data Delivery in Wireless Sensor Networks

Petcharat Suriyachai

In order to support real-time applications, network components in wireless sensor networks (WSNs) must ensure that data arrive their destination within a calculated time. These components are mostly based on a medium access control (MAC) protocol, and their implementation leads to the existing large pool of MAC protocols. In contrast to this approach, we present a modular framework that uses an existing MAC protocol and a new network dimensioning method. The framework defines how to create a wireless sensor network with a guaranteed maximum of message delivery time, and therefore it can enable the target real-time applications.
