Cell Breathing and Cell Capacity in CDMA: algorithm & evaluation
Ihsan UlHaq, Adnan Shafiq, Khawaja M. Yahya, Mohammad Naveed Iqbal · 2010
The aim of this article is to present a resource allocation algorithm to prevent Cell Breathing and facilitate Proactive Group Handover for Code Division Multiple Access based third generation cellular networks. The algorithm helps to prevent Cell Breathing and thereby increases the Cell Capacity in terms of density of Mobile Stations (User Equipment), as the Mobile Stations at the edge of cell will not be disconnected due to Cell Breathing. One of issue with Handoff management is to ensure quality of service for wireless connections. Here by QoS we mean to reduce the probability of forced termination during handoff. Our proposed algorithm helps in successful Group handover and thus guarantees QoS by making the resources available in the target cell. Simulation study has been performed to verify the proposed algorithm. The algorithms can provide better QoS in vehicular environment where many Group Handovers occurs.
