Abstract-The IEEE 802.11n network main feature is to support high throughput of more than 100Mbps at the MAC layer. To achieve this, the 802.11n Task Group has introduced frame aggregation technique which reduces the overhead and increases the channel utilization efficiency. Some recent researches have enabled an A-MSDU selective retransmission which makes it robust against error. In this paper, we propose a scheduler based on an A-MSDU aggregation mechanism that supports small size and high sensitivity traffics, and enable prioritization according to the QoS requirements of the traffic classes.

Physical Cell Identity (PCI) assignments and conflicts are still posing huge challenges in the LTE-femtocell based network. This challenges stem from the problem of only 504 unique PCls are available in the LTE network. In this work we propose an approach to solve this problem with minimum needs of human intervention, besides preserving the network resources by discarding the need of periodically updating the network neighbor list and also discarding the need to resolve searching conflict and healing.
