This paper presents the study of an access point (AP) deployment strategy which aims to reduce the energy expenditure of ubiquitous motorway network coverage while ensuring Quality of Service (QoS) requirements are maintained at acceptable levels. For this reason, we, in this paper, study the consumption of energy in a scenario where three operational APs are deployed on a motorway with and without...
Providing quality of service (QoS) to the passengers at an airport is extremely challenging due to the dynamic nature of the environment in which they operate coupled with their own behaviour. With the regular arrivals and departures of flights, passenger flow tends to continuously change making it more difficult to maintain the required QoS. Moreover, deploying an ad hoc system in such a scenario...
In this paper, a pico-cellular airport traffic model is proposed which supports Engset distributed fresh call arrival process and General distributed handoff process with Dynamic Channel Allocation (DCA). The proposed model enables load balancing using DCA and uses a three-dimensional Markov chain to compute traffic congestion and call congestion for any kind of traffic streams, including Pure Chance...
This paper aims to show the effects of road congestions arising from motorway roadworks on the performance of vehicular mobile networks. Using vehicular traces from loop Ids on a length of the M4 motorway in the UK, the impact of congestion due to speed control measures and lane closures in a section of the coverage area is simulated to show the resulting network effects on a fixed channel allocation...
Routing in Vehicular ad hoc networks (VANETs) is considered to be an extremely challenging task due to the frequent and dynamic changes in the topology. The random speed and unpredictable movement of vehicular platforms causes the network to disconnect quite frequently. However as each vehicle in the network can obtain its exact location by using a Global Positioning System (GPS), position based routing...
The application of Radio-over-Fiber (RoF) technology in cellular systems has attracted considerable attention in recent time. Consequently, the indoor personal communication systems (PCS) using the RoF architecture needs reinvestigation in performance domain. In this paper, we investigate such a system, which uses tiny cells (pico-cells) with limited number of users. We develop a corresponding traffic...
