Batteries of modern mobile devices remain severely limited in capacity, which makes energy consumption a key concern for mobile applications, particularly for the computation-intensive video applications. Mobile devices can save energy by offloading computation tasks to the cloud, yet the energy gain must exceed the additional communication cost for cloud migration to be beneficial. The situation...
In wireless sensor networks, grid-based clustering and routing schemes have attracted considerable attention due to their simplicity and feasibility. In this paper, we adopt a hexagonal tessellation approach and propose a Fast Hexagonal Clustering (FHC) algorithm for efficient data collection. The traffic load is intentionally concentrated at a small portion of Cluster Heads (CHs) and Convergence...
