An Improved Zig Bee Routing Algorithm Based on Energy Balance

In order to solve the problem that the existing routing protocols in ZigBee have unequal node energy consumption and easy to cause the network to divide and die, an energy balanced ZigBee routing algorithm is proposed, The algorithm improves the ZBR routing algorithm.The improved algorithm takes into account the protection of the low energy of the node, control the direction of RREQ packet transmission, reduce data flooding, and at the same time build more than one path in the route discovery phase.If the primary path fails, it can switch directly to the backup path to reduce delay and reduce energy consumption.The simulation results show that the improved routing algorithm can effectively reduce the network energy consumption, balance the node energy and prolong the network lifetime.
