Location-information based distributed multicast routing algorithm for sensor networks
Junyi Li · Jisuanji gongcheng yu sheji · 2009
An innovative distributed multicast routing algorithm for sensor networks is presented,based on nodes' location information.The main ideas of this new algorithm are the followings:At first,it forms clusters according to nodes' location information distributedly.And then,by using ant algorithm,every cluster head distributedly obtains the optimal path of the minimal total hops from itself to the des-tination nodes.Fina-lly,after having collected and aggregated the related data in its own cluster,every cluster head sends the aggregated data to the destination nodes separately along its selected optimal paths.Theoretic analysis and simulation results show that the new al-gorithm is energy efficient and has good routing performances.
