摘要

自适应阵列天线(AAA)技术在自组织网络中的应用仍然引起了网络界的广泛讨论。即使AAA被视为一种避免干扰的解决方案,在自组织网络中错误地实现AAA也会导致网络性能的普遍恶化。前向干扰避免(FIA)概念被提出作为解决这一问题的一种方法。FIA概念允许在传输开始之前预测,由自组织网络中的节点打算进行的通信是否成功,以及该节点是否会干扰其他通信。它通过使用两个阈值来评估流量需求。在本文中,我们解释了如何估计这两个阈值,因为它们对其正确运作至关重要。我们通过使用累积分布函数CDF来展示如何根据网络需求选择值,并通过线性规划优化来证明其正确性。

FIA criteria estimation for adaptive array antennas in ad hoc networks
Application of adaptive array antenna (AAA) technology in ad hoc networks still causes a lot of discussion in the network community. Even if AAA is seen as a solution for interference avoidance, wrong implementation of AAA in ad hoc networks can lead to a general deterioration of network performance. Forward interference avoidance (FIA) concept has been proposed as one solution to this problem. The FIA concept allows to foresee, before the start of transmission, if a communication, intended by a node in an ad hoc network, will be successful and if this node could interfere with other communications. It does so by evaluating traffic demands by using two threshold values. In this paper, we explain how to estimate the two threshold values as they are vital to its correct functioning. We show how the values may be chosen depending on network requirements by using a cumulative distribution function CDF and proof its correctness by optimizing with linear programming.
