	abstract = {The Networked Distributed POMDPs (ND-POMDPs) can model multiagent systems in uncertain domains and has
begun to scale-up the number of agents. However, prior work in ND-POMDPs has failed to address communication. Without
communication, the size of a local policy at each agent within the ND-POMDPs grows exponentially in the time horizon. To
overcome this problem, we extend existing algorithms so that agents periodically communicate their observation and action
histories with each other. After communication, agents can start from new synchronized belief state. Thus, we can avoid the
exponential growth in the size of local policies at agents. Furthermore, we introduce an idea that is similar to the Point-based
Value Iteration algorithm to approximate the value function with a fixed number of representative points. Our experimental
results show that we can obtain much longer policies than existing algorithms as long as the interval between communications is
small.},
