Many tasks in computer systems could be abstracted as distributing items into buckets, so that the allocation of items across buckets is as balanced as possible, and furthermore, given an item’s identifier it is possible to determine quickly into which bucket it was assigned. A canonical example is a dictionary data structure, where ‘items’ stands for key-value pairs and ‘buckets’ for memory lo...

This paper discusses the multiple node disjoint paths protocol (MNDP) for mobile ad hoc networks. A mobile ad hoc network is a collection of mobile nodes that cooperate without networking infrastructure so as to form a temporary network that meets some immediate needs. The MNDP protocol detects multiple paths and distributes transmitted packets over these paths. Such distribution reduces conges...

The usages of the Internet are more and more important. Under the consideration of cost and redundant, multiple link structure for connecting to the Internet for an organization to reduce network traffic jam problem is more necessary. Most of the time, multiple line connections mean multiple Internet Service Provider (ISP). It leads to the management problem for traffic load balancing and multi...

The East China Power Grid (ECPG) is the biggest regional power grid in China. It has the biggest installed capacity of pumped storage power plants (PSPPs) and is responsible to coordinate the operation of its five provincial power grids. A recent challenge of coordinating operations is using PSPPs to absorb surplus energy during off-peak periods and generate power during peak periods. Differing...
