Energy Aware Communications Framework For Ieee 802.15.4 Wireless Sensor Networks, Rodolfo De Paz Alberola

Theses

A wireless sensor network (WSN) is a network of sensor nodes that functions in a cooperative manner to monitor the changes in the physical environment. Typically, sensor nodes are deployed in places with difficult access, if any, to an external power supply thus requiring battery power. Therefore, WSN communication protocols must be designed with energy efficient and self-organizing capabilities in mind. In this context, the IEEE 802.15.4 standard is being widely employed for the lower layers of low-cost, low-rate and low-power wireless sensor communications due to its potential to fulfil requirements of various monitoring and control applications. However, the specification …
