Taguchi Based Self-Configure Data Rate Optimization AODVUU Routing Parameters In MANET Over Optical Network Performances

Research and development advancements in the area of wireless technologies give rises of mobile ad hoc networks (MANET) domain but is constrained to the single networks and stand alone. Furthermore, the communication networking applications requirements mostly still depends on fixed infrastructure networks that lead to MANET need to communicate with internet. Consequently, the traditional mobile routing protocols proposed for MANET are inefficient but play an equivalent important role in the performances of mobile wireless network over optical backhaul with focusing of MANET of the wireless domain in access network. Routing protocols procedures are controlled with a set of parameters from being dragged to undesired situations such as un-optimized Quality of Service (QoS) resource consumption. These parameters have a direct impact on the efficiency of a routing protocol and the overall MANET network performances. This paper proposed an offline optimization through simulation design of experiment of the AODV-UU parameters of MANET is evaluated by performing Taguchi signal to noise ratio (SNR) method for fine-tuning the AODV-UU routing parameters using the OMNeT++ software. The work is further extended with self-configure multiple data rates (SCMDR) scheme-a cross-layer-specific technique. AODV-UU with Taguchi tuned under the proposed SCMDR scheme is compared with AODV-UU configuration of oRiG scheme also as respects to previous work is examined based on capacity consumption, end-to-end delay metric and energy consumption metric under the varying speed scenario. The obtained results showed that, AODV-UU with Taguchi configuration outperformed the AODV-UU for the mention performance metrics here. The existing of current access network of the telco operators can benefit from the proposed improvement here

Design of a cell selection mechanism to mitigate interference for cell-edge macro users in femto-macro heterogeneous network

The Femto-Macro heterogeneous network is a promising solution to improve the network capacity and coverage in mobile network. However interference may rise due to femtocell deployment nearby to macro user equipment (MUE) within macrocell network coverage. Femtocell offers main priority in resource allocation to its subscribed femto user equipment (FUE) rather than unsubscribed MUE. MUEs will suffer severe interference when they are placed near or within the femtocell area range especially at the cell edge. This phenomenon occurs due to the distance is far from its serving macro base station (MBS) to receive good signal strength. This paper presents a design of cell selection scheme for cell-edge MUE to select an optimal femto base station (FBS) as its primary serving cell in physical resource block allocation. In this study, the proposed cell selection consists of four main elements: measuring the closest FBS distance, Signal to Interference-plus-Noise-Ratio (SINR), physical resource block (PRB) availability and node density level for the selected base station. The main goal is to ensure cell-edge MUE has priority fairly with FUE in physical resource block allocation per user bandwidth demand to mitigate interference. Hence, the cell-edge MUE has good experienced on receiving an adequate user data rate to improve higher network throughput
