Femtocell network optimization applying vertical handoff algorithm

Femtocells are low power base stations that provide better radio coverage to portable users through femtocell access point (FAP) at the indoor scenario. The access node named as FAP, perform as the base station (BS) for the femtocell and take help of internet as backhaul to get connected with MBS. In these emerging dual layer networks, handoff facilitates for a mobile user moving from a network coverage of macro base station (MBS) to a network coverage of femto base station (FBS) to get advantages of quality network service of femtocells with respect to user satisfaction and system performance. In this paper, a strategy-based framework that implicates handoff strategies into network configuration is invoked to enact vertical handoff protocols in order to get a satisfactory outcome for both the user and the network. In vertical handoff, the process of deciding to accomplish handover based on the assessment of handoff metrics, which are the calculated quantities that provide piece of information of whether or not a handoff is require. Here, we optimize the femtocell network by vertical hand off considering salient features like reliability, latency and data rate, mobile terminal conditions, price function, network conditions, and user priority. Several optimization scheme like received signal strength (RSS) base algorithm, RSS base algorithm including mobility, multiservice vertical handoff decision algorithm (MUSE-VDA) are introduced to escalate the hand off decision. At the end, effectiveness of the scheme is verified by extensive Matlab simulations.
