Intermittent connectivity destroyed the building blocks of the traditional network—end-to-end principle,and the space network further posed a great challenge because of the characteristics of long,variable latency,low band width,high noise and so on asymmetric links.

As the traditional routing protocols can not adapt to the intermittent connection of mobile networks due to the sparse distribution,frequent disruption or periodical motion of nodes,a new routing protocol marked as MSAR is proposed based on the awareness of node motion scope with the uncertainty of network status.

The availability of separating acid-production phase and methane-production phase through intermittent aeration, and accelerating stabilization of solid waste through inoculation was studied, and the feasibility of on-site removing pollutants was evaluated.

In order to study the impact of diverse compositions of refuse and recycled leachate on in-situ nitrogen removal under intermittent aeration conditions,simulated landfill columns were set up to investigate nitrogen conversion.
