The basic reason of handover is to stay connected to the Internet with the intention of reducing connection quality deterioration. In a ubiquitous network, mobile nodes often perform handovers to stay connected to the Internet. These mobile nodes sometimes suffer from performance degradation during handover due to radio interference and reduction of signal strength. Therefore, we identified two goals in our paper. The first goal of this paper is to prove that trend based handover triggering mechanisms are better indicators of link going down as compared to threshold based handover triggering mechanisms. The second goal of this paper is to propose our idea of using frame retransmission trend in triggering handovers in order to achieve improved communication quality performance. In our work, we compared signal strength and frame retransmission as the handover decision criterion by means of simulations. Finally we present the effectiveness of our proposed frame retransmission trend as the handover decision criterion to achieve improved communication quality.
