Service Aggregation in Motional Rainfall Cell Queues Over Wireless Radio Links

Abstract

Recently, rainfall process over wireless radio links has been designated as an unstable semi-Markovian queue with chaotic service description during rain events. A formal explanation for such queue service behaviour in natural queues like rainfall phenomenon, may be related to the presence of stratified cloud layers representing rain cells, during rain events. In this paper, the concept of service aggregation of rainfall queues obtained from ground measurements is examined in Durban (29°52'S, 30°58'E) in South Africa and Butare (2°36'S, 29°44'E) in Rwanda are further analysed. Our results suggest that - two or more parallel queue servers maybe present - at different strata in the troposphere during typical rain events at these sites.
