There are many papers investigating these issues in various ways [7, 8, 10–12, 14]. Today’s challenge is to find protocols (or deployments) which

However, in distributed systems, networks, and cooperative computing systems, the numbers of users, permissions, and resources usually are large, and the relations among them are very complicated. Thus central

With an emphasis on a preamble design for multichannel separation, we address the channel estimation in MB-OFDM system with multiple antennas. By properly designing each pre

In many cases, it is very useful to have a middleware that takes control over the connection management, fault management, and communication management. Most current approaches concentrate on a subset of topics to be determined in this context. This chapter will take a close
