The overlay of microcells over macrocells offers new opportunities and is cost effective, which makes the handover in such a micro-cellular environment an important issue. The objective of this study is to analyze and prove the truthfulness of a new protocol proposed, which guarantees no packet loss during the handoff. The study here emphasizes on the data integrity issue, since it is the key factor affecting the throughput performance of the transport layer. It is shown that usage of the Internet Protocol leads to packet loss in the presence of handover. Simulation results reveal that the proposed new protocol preserves the data, even in the presence of handoff. A queuing model is built to illustrate the effect of data integrity on the gateway. Simulation results of this model exhibit the burden on the gateway. The three phases of the analysis mentioned above, are focused in displaying the data integrity issue.
