“…Fig. 5 shows the call blocking rate by varying the traffic intensity level using the proposed scheme, the fixed handover offset scheme, and the directed handover scheme [11]. We observe that the call blocking rate of the fixed handover offset scheme increases linearly with an increase in the traffic intensity level.…”

“…There are several proposals to resolve load imbalance in mobile communication networks [1][2][3][4][5][6][7][8][9][10][11][12]. In [1][2][3][4], mobile stations (MSs) at the cell edge were handed over to neighbor base station (BS) with the strongest signal by reducing the pilot power of BS.…”

This paper proposes a scheme for distributed load balancing in mobile communication networks based on supervisory control framework. Using load information exchanged with neighboring cells, the "supervisors" that reside in the base stations distribute load among cells by controlling handover parameters in a distributed manner. The supervisors are designed so that the load difference among neighboring cells are kept under a pre-defined value. Results from systematic analysis and simulation indicate that our scheme effectively balances traffic load among cells and reduces call blocking rate of the overloaded cells.

“…Both BS-initiated directed handovers and MSinitiated rescue handovers are conducted in parallel to offer better load balancing scheme enabling satisfactory QoS and much fewer ping-pong effects [27] Potential Research Solutions: It should be noted that, as the QoS might get hampered in case of both long and short scanning intervals, optimisation of scanning intervals is an important issue. An efficient Adaptive Channel Scanning algorithm in a multi-MS oriented MWiMAX environment, relying on the exchange of configuration parameters between the NBSs in order to find out the required scanning time for a MS, is proposed in [21].…”

“…This is a problem in the MWiMAX scenario as well. Though the MWiMAX Forum has supported a Radio Resource Management (RRM) framework for efficient load balancing and resource utilization [38] with the help of BS-initiated directed handovers [27], the specification provides only a framework and lacks any detailed implementation concepts and algorithms [39]. Thus, it is an open research issue.…”

Abstract-The next-generation Wireless Metropolitan Area Networks, using the Worldwide Interoperability for Microwave Access (WiMAX) as the core technology based on the IEEE 802.16 family of standards, is evolving as a Fourth-Generation (4G) technology. With the recent introduction of mobility management frameworks in the IEEE 802.16e standard, WiMAX is now placed in competition to the existing and forthcoming generations of wireless technologies for providing ubiquitous computing solutions. However, the success of a good mobility framework largely depends on the capability of performing fast and seamless handovers irrespective of the deployed architectural scenario. Now that the IEEE has defined the Mobile WiMAX (IEEE 802.16e) MAC-layer handover management framework, the Network Working Group (NWG) of the WiMAX Forum is working on the development of the upper layers. However, the path to commercialization of a full-fledged WiMAX mobility framework is full of research challenges. This article focuses on potential handover-related research issues in the existing and future WiMAX mobility framework. A survey of these issues in the MAC, Network and Cross-Layer scenarios is presented along with discussion of the different solutions to those challenges. A comparative study of the proposed solutions, coupled with some insights to the relevant issues, is also included.
