The use of wireless sensor networks in home automation WSNHA is attractive due to their characteristics of self-organization high sensing fidelity low cost and potential for rapid deployment. Although the AODVjr routing algorithm in IEEE 802.15.4 ZigBee and other routing algorithms have been designed for wireless sensor networks not all are suitable for WSNHA. In this paper we propose a location-based self-adaptive routing algorithm for WSNHA called WSNHA-LBAR. It confines route discovery flooding to a cylindrical request zone which reduces the routing overhead and decreases broadcast storm problems in the MAC layer. It also automatically adjusts the size of the request zone using a self-adaptive algorithm based on Bayes theorem. This makes WSNHA-LBAR more adaptable to the changes of the network state and easier to implement. Simulation results show improved network reliability as well as reduced .
