KILAVI Wireless Communication Protocol for the Building Environment - Networking Issues

The KILAVI communication protocol is developed for low-power and low data rate wireless communication in the building environment. The KILAVI network links together building control and monitoring applications into an intelligent self-configurable system that can be easily controlled and monitored by the consumer through wireless and wired interfaces either locally or remotely. A KILAVI network consists of master, intermediate and sensor nodes. The master manages communication in the network, handles security, carries out node registration, and initiates the device control and monitoring tasks. Intermediate nodes are sensor/control nodes with data relaying capability that may be used to implement a multi-hop network. Power scarce sensors are primarily kept in the sleep state to minimize power consumption. Sensors wake up only to transfer or query data. Lifetime analysis on practical KILAVI nodes shows very promising results
