Network congestion will increase as network speed increases. New control methods are needed, especially for handling “bursty” traffic expected in very high speed networks such as Asynchronous Transfer Mode (ATM) networks. Users should have instant access to all available networks and required band widths when required. In this paper, we look at communication protocols, which can have significant impact on the overall energy dissipation of these networks. Based on findings that the conventional protocols of direct transmission, minimum-transmission-energy, multi hop routing, and static clustering may not be optimal for sensor networks, we propose E2R2 (Energy Efficient Reliable Routing), a clustering-based protocol that utilizes randomized rotation of local cluster base stations (cluster- heads) to evenly distribute the energy load among the sensors in the network. E2R2 uses localized coordination to enable scalability and robustness for dynamic networks, and incorporates data fusion into the routing protocol to reduce the amount of information that must be transmitted to the basestation.
