TL;DR: This paper proposes a new distributed event delivery method for MMORPG (Massively Multiplayer Online Role Playing Games) that achieves practical performance and includes a technique to efficiently and seamlessly switch sub spaces to be observed while each player's view moves around in the game space.

TL;DR: A genetic algorithm (GA) based scheme to find a near optimal solution in practical time to k-cover the field and maximize the WSN lifetime by moving mobile sensor nodes to appropriate positions for a WSN consisting of both static and mobile sensor node which periodically collect environmental information.

TL;DR: The authors show that the FPGA circuits synthesized based on the proposed method run much faster and consume much lower power than software implementation on a PC and the model can predict the size of the resulting circuit accurately enough.

TL;DR: An algorithm where mobile nodes autonomously and probabilistically decide their actions without a central control is proposed, which reduces cellular network usage by about 93% compared with a case that all nodes download video ads via cellular network, and works effectively in cases with a large number of nodes and high mobility.

TL;DR: This paper extends the existing personal navigation system called P-Tour in the following two ways: allowing users to optimize their tour schedules under multiple conflicting criteria such as total expenses and satisfaction degrees; and navigating users to the next destination in a more efficient way.
