Clustering is used commonly in ad hoc networks for hierarchical routing. Size-bounded clustering has been proposed to restrict the maximum size of a cluster so that the routing load, and hence the energy drain, on the clusterhead is bounded. However, all the existing size-bounded clustering algorithms take the size bound as the number of nodes in the cluster. This approach may still result in high...
Despite the wide spread of interest to ad hoc networks and the rapid development in wireless communication technologies, energy consumption still remains a critical issue. The use of a low-power mode has been adopted by many approaches in the literature to conserve energy. It allows nodes to switch to the sleeping mode whenever possible to conserve energy. However, most of these approaches do not...
In recent years, various types of ad hoc routing protocols have been studied in the mobile ad hoc networks. Specifically, the clustering hierarchical routing algorithms have been developed to increase the system performance. Hierarchical structure has inevitably brought some drawbacks, maintaining the hierarchical structure needs more complicated cluster heads selection algorithm, which may result...
The large deployment of ad hoc networks is already throttled by the slow advancement of battery technology. In fact, wireless devices usually rely on portable power sources such as batteries to provide the necessary power. The use of low-power mode was adopted by many approaches in the literature to conserve energy. However, most of these approaches do not take account of the impact of such mode on...
