The communications needs of monitoring and control of the electric grid is traditionally catered for by wired communication systems. These technologies ensured high reliability and bandwidth but are however very expensive, inflexible and do not support mobility and pervasive monitoring. The communication protocols are Ethernet-based that used contention access protocols which result in high unsuccessful transmission and delay. The use of embedded wireless sensor and actuator networks for monitoring and control of the electric grid requires secure, reliable and timely exchange of information among controllers, distributed sensors and actuators.
