Partially shaded conditions are common in all kinds of PV systems. The mismatch phenomenon not only affects the power generated by solar system, but also leads to security problem. Still, under partially shaded conditions, the P-V curve of PV arrays will have the characteristics of multi-summit, which makes the maximum power point tracking very difficult to accomplish. In this paper, the PSO algorithm...
First we analyze the shortcomings of existing routing protocols in intermittently connected mobile networks (ICMN) such as high delivery delay, low success rate and cannot adaptive to the different network environment. With this in mind, we propose a new routing scheme called adaptive multiple copy multiple hop algorithm (AMM). By collecting the simple information about the status of the network,...
First we introduce the characteristics of the opportunistic networks, and analyze the shortcomings of the main acquisition strategy in this kind of network, such as low success rate and low efficiency. With this in mind, we propose a hybrid strategy called "Pull-Push" Based Algorithm (PPBA). In this algorithm, not only the source node actively disseminates some copies of service information,...
