Routing plays a major role in increasing the energy efficiency of a wireless sensor network. In a cluster based wireless sensor network, cluster head can forward the data to the base station either directly or indirectly (multi-hoping). However, in multi-hop routing energy saving is more as compared to direct transmission. Further, the selection of energy efficient routing schedules helps in increasing...
Clustering in wireless sensor networks improves lifetime of the network by load distribution, data aggregation and use of clusterheads to efficiently route messages to the central gateway. Parameters governing creation of optimal clusters are often numerous and domain-specific. The challenges increase with mobile nodes due to faster temporal change in one or more parameter values like speed and distance...
