Abstract:
Recently, wireless networks and mobile terminals are rapidly evolving. Wireless networks are evolving towards het- erogeneous overlaying environment, while the mobile terminals evolve towards having multi-interface functionality in order to face seamless service continuity. Traditional horizontal handover management schemes that mainly depend on signal strength for decision making are unable to fulfill ubiquitous and seamless mobility across heterogeneous networks. Vertical handover is more related to convenient criteria such as user preferences or application requirements. The use of location information in decision making would certainly enhance horizontal or ver- tical handover mechanisms by supporting optimized handover management. For that, using the location information and the mobile terminal movement can participate to a handover decision improving the handover execution procedure. For example, when a mobile terminal is moving with a certain velocity, it can perform handover execution uselessly that affects handover performance. This paper proposes and describes a pre-selecting access points algorithm in a location-aided handover management scheme in order to reduce unnecessary handovers in a moderate mobility scenario. It shows by simulation the feasibility of the proposed algorithm applied to a random mobility and a dense environment.
