Link Analysis of Mobile Nodes in Ad Hoc Network Using Ricean Fading Channel Model

Abstract

Abstract-Communication channels are one of the important components of the wireless mobile ad hoc network. The link connectivity among mobile nodes moving in these channels can be measured through various performance metrics. This paper analysis the link connectivity of mobile nodes in one of the well known channel model, the Ricean fading channel, in which a strong dominant signal component is always present among several multipath signals received by receiver. Two performance matrices have been used to evaluate the link analysis of nodes. These are Link duration and Link ratio. It is discovered that the link duration is dependent on Ricean Factor K where as Link ratio shows irregular results, which represent true picture of link connectivity in the presence of fading.Index Terms-Mobile ad hoc networks, ricean fading, ricean factor k, mobility model, link duration, link ratio.
