In vehicular ad hoc networks, autonomous vehicles generate a large amount of data prior to support in-vehicle applications. So, big storage and high computation platform are needed. On the other hand, for networks at cloud requires low latency. Applying edge (EC) as new computing paradigm has potentials provide services while reducing latency improving total utility. We propose three-tier EC fr...

Batched stream processing systems achieve higher throughput than traditional stream processing systems while providing low latency guarantee. Recently, batched stream processing systems tend to be deployed in cloud due to their requirement of elasticity and cost efficiency. However, the performance of batched stream processing systems are hardly guaranteed in cloud because static resource provi...

Horn's model is generalized to state that the "optimal" pattern o f distribution for foragerswill correlate with the degree o f resource patchiness; in particular (1) where resource attributes are less patchy, the "optimal" distribution for foragers is to be dispersed, and (2) where resource attributes are more patchy, the "optimal" distribution for foragers is to be aggregated. "Optimality" is...
