Wireless monitor system are widely used in recent years, but there are a few problems to solve, such as scalability and adaptability, and monitor system based on MANET has more difficulties because of multi-hop links and mutable channels. A new MANET monitor system based on Service-oriented architecture (MMS-SOA) is proposed to make the system easier to manage dynamically such as dynamic deployment,...
This paper mainly introduces a TSALS (tree search active link selection) algorithm working in a centralized mode. In this scheme, each node is equipped with a third generation mesh router, which owns two relay transceivers and can be tuned among multiple channels. The major goal of this solution is to reduce the length of scheduling under an interference-aware restriction. The feasibility and efficiency...
In wireless relay networks, the use of multiple antennas at both the source and destination can increase the capacity linearly with the number of antennas. In this paper, we investigate amplify-and-forward dual-hop MIMO relay networks without channel state information at the relay nodes, i.e., noncoherent case. In contrast to the conventional approach where the available power is equally distributed...
Recently, orthogonal frequency division multiplexing (OFDM) has become a popular technique for transmission of signals over wireless channels. Also, multiple-input multiple-output (MIMO) is one of the most promising technologies for assisting fading and improving link reliability without sacrificing bandwidth efficiency. The combination of OFDM and MIMO seems to be the key technology in next generation...
