Abstract
Macro-Femto Hybrid Cellular Network (MFHCN) has been considered as one of the most promising infrastructure for the upcoming next generation cellular network. Femto-Cell (FC) is very effective when it comes to reducing poor signal coverage. The range of the device might be low but it functions to reduce the traffic congestion of the larger Macro Network as well as provide enhanced data rate for both voice and data transmission. In short, it provides better Quality of Service (QoS), i.e., reduce congestion, increase capacity, reduce system outage, while using minimal power consumption. In this work we propose a suboptimal Resource Allocation algorithm for MFHCN. Multiuser and Multiservice are considered in this proposed model. A priority parameter is introduced to maintain fairness amongst all users. By doing so, we were successful in achieving improved outage probability without compromising the total system throughput.
Highlights
A typical human behavior is that human beings prefer reliability
The circle marked straight line represents the outage probability of MC using optimal power allocation when 50 FCs are deployed in the system
The circle marked dashed line which represents the outage probability of the MC while using our proposed model, behaves in the same way but its outage has slightly increased since we have introduced fairness into our system
Summary
A typical human behavior is that human beings prefer reliability. Every individual’s daily schedule demands the availability of technologies whenever needed. If we look at the usage of the internet in our daily lives, even the prominent concept of Third Generation (3G) internet, which has been so successful in fulfilling everyone's need, is eventually not good enough if it is not accessible to the user whenever he/she demands, either due to being on the cell edge area or indoors (e.g. basement) For this reason many researches are being conducted to enhance the system capacity while using the current technology. Since we are using Microwaves for transmission, so if we exceed a certain limit, it will cause human health hazard (Revermann, 2002) and cause wastage of power Another solution that we came across is the use of Cooperative Relay System (Kaiser, 2010). After different reviews and logics, we are considering to use of FCs as an efficient solution in terms of fairness and increasing the total system capacity
