摘要
Learning from the conventional practice of network IP address format, this paper proposed an IP-format-based algorithm for ZigBee energy-balanced routing protocol optimization. The algorithm combines node’s cluster address and node’s network short address into a new address and divides the address’s field as IP-format. So that the address will contain information of the network’s topology and provide decision base for a routing algorithm to optimize the original algorithm selection criteria. Meanwhile, in order to improve the ratio of valid data packets and reduce routing overhead, the new algorithm controls the general direction and the number of hops of the RREQ packets to reduce unwarranted data packet transmission. Finally, the simulation carried out on NS platform demonstrates the algorithm’s superiority on network’s delay jitter, overhead and residual energy.
