Design and implementation of a generic hybrid wireless sensor network platform

There exist several platforms of wireless sensor networks. Each of them has specific characteristics, such as hardware and software architecture, for example a processing unit, RAM memory, wireless technology. The complexity of novel applications and the number of existing platforms have resulted in the design of hybrid wireless sensor networks. In this paper, we describe the architecture and implementation of a hybrid wireless sensor networks based on the Tmote sky sensor and Fox board platform. They use IEEE 802.15.4/ZigBee and Bluetooth respectively. The paper presents a new model of sensor network which is a mixture of the both previous platforms using only IEEE 802.15.4 wireless technology. We have also compared IEEE 802.15.4 and Bluetooth. In this work, a generic platform of wireless sensor networks with several levels of sensors is presented.
